The Reinforcement of the Philippines

Chapter 3

            When General MacArthur assumed command of U.S. Army Forces in the Far East, there was no program in the War Department for any immediate large-scale reinforcement of the Islands. As a matter of fact, the War Department specifically told MacArthur that he could have "no additional forces, except approximately 400 reserve officers to assist in training the Philippine Army...... " Within a few days, there was a complete reversal of policy in the War Department. The first sign of this change came on 31 July 1941 when General Marshall approved a proposal by the War Plans Division to reinforce the Islands' defense "in view of the possibility of an attack."  The next day MacArthur was informed that he would receive substantial reinforcements and Marshall told his immediate staff, "It was the policy of the United States to defend the Philippines." This statement so impressed the Chief of the War Plans Division that he entered it in his office diary .

            The reasons for this change of policy are nowhere explicitly stated. Undoubtedly many factors both political and military contributed to the American Government’s firm stand in July and August 1941. One of these was recognition of the potentialities of air power and especially of the Army's new heavy bomber, the B-17, called the Flying Fortress. In Stimson's opinion, the success of B17 operations in Europe was responsible for creating an optimistic view in the War Department that the Philippines could be successfully held. A striking force of such heavy bombers, it was argued, would act as a deterrent to Japanese advances southward and would strengthen the United States position in the Far East.

            Another cause for optimism was the recall of General MacArthur to active duty. No one knew as much as he about the Philippines and no one believed more completely that it could be held if the Japanese allowed sufficient time for reinforcement.

            The possibility of establishing an effective defense against Japan in the Philippines and thereby preventing Japanese domination of the Western Pacific without altering the major lines of strategy already agreed upon "had the effect," Stimson said, "of making the War Department a strong proponent of maximum delay in bringing the Japanese crisis to a climax.... In their [Stimson’s and Marshall’s eyes the Philippines suddenly acquired a wholly new importance and were given the highest priority on all kinds of all kinds of military equipment.”

 

Ground Forces

            The first official War Department program for a large-scale reinforcement of the Philippines during this period was proposed by War Plans on 14 August. In a memorandum for the Chief of Staff, General Gerow argued that those reasons which had limited the size of the Philippine garrison -- lack of funds, personnel, and equipment, plus the inability of the Navy to support a large force -- were no longer entirely valid. With its present strength, he pointed out, there was a real doubt if the Philippine garrison could resist a Japanese attack, a contingency which he considered probable in view of Japan's attitude. To strengthen the garrison and increase its chances of holding Luzon and especially Manila Bay, General Gerow recommended that the Philippines be reinforced by antiaircraft artillery, modern combat planes, and tanks. The amount that could be sent, Gerow admitted, would be limited by the number of ships available for transport duty to the Far East. "The best that can be done at the moment," therefore, would be "to adopt a definite plan of reinforcement and carry it forward as availability of shipping permits."

            Gerow's recommendations were approved and two days later, on 16 August, General MacArthur was notified that the following units would sail from San Francisco between 21 August and 5 September the 200th Coast Artillery Regiment (AA) consisting of 76 officers and 1,681 enlisted men; the 194th Tank Battalion (less Company B), with 54 tanks, 34 officers, and 390 enlisted men; and one company (155 men) of the 17th Ordnance Battalion.

            There had been some mention earlier of the possibility of sending a division to the Philippines, and on 5 September the Chief of Staff asked MacArthur if he wanted a National Guard division (probably the 41st). MacArthur replied that he did not need this division since he already had one U.S. Army division (the Philippine Division) and was mobilizing ten Philippine Army divisions. He asked instead for authority to reorganize the theoretically square Philippine Division into a triangular division, adding, "Equipment and supply of existing forces are the prime essential."  "I am confident if these steps are taken with sufficient speed," he said, "that no further major reinforcement will be necessary for accomplishment of defense mission.”

            The reinforcement of the Philippines now enjoyed the highest priority in the War Department. MacArthur's request for permission to reorganize the Philippine Division was approved immediately. He was promised additional aircraft as well as the funds needed for airfield construction and the antiaircraft guns and equipment to protect the fields once they were built. “I have directed," wrote General Marshall, "that United States Army Forces in the Philippines be placed in highest priority for equipment including authorized defense reserves for fifty thousand men."

            As a result, General MacArthur's requests for men and supplies during the next few months received almost instant approval by the War Department. "I wish to express my personal appreciation for the splendid support that you and the entire War Department have given me along every line since the formation of this command," he told the Chief of Staff in a personal letter. "With such backing the development of a completely adequate defense force will be rapid.”

            Through no fault of the War Department or a lack of desire on the part of the Chief of Staff, General MacArthur's confidence in the rapid development of an adequate defense for the Philippines was not entirely justified. The task was a heavy one and limited by many factors beyond the control of the military. The industrial capacity of the United States was only just beginning to turn to the production of war material; the needs of a rapidly expanding citizen army had to be met; Great Britain and Russia were in critical need of supplies; and shipping space was extremely limited.

            The reinforcements promised MacArthur on 16 August were dispatched with the greatest speed and by 12 September General Marshall was able to report considerable progress. The antiaircraft artillery regiment, the tank battalion of 54 tanks, and reserve supplies had already been shipped from San Francisco. During the month, 50 more tanks, and 50 self-propelled mounts for 75-mm. guns were to be sent.

            These reinforcements reached MacArthur before the end of September. The arrival of the 200th Coast Artillery Regiment (AA) gave him 12 additional 3-inch guns, 24 37-mm. guns, and a similar number of machine guns. Armored reinforcement consisted of the 192d and 194th Tank Battalions each with 54 tanks. And he could count on 25 more 75-mm. guns on self-propelled mounts (SPM) already en route and due to arrive in Manila on 15 October.

            The arrival of the two tank battalions with their 108 light tanks, M-3, were a welcome addition to the Philippine garrison. On 21 November a Provisional Tank Group consisting of the 192d and 194th Tank Battalions and the 17th Ordnance Company (Armored) was established, with Col. James R. N. Weaver in command.

            As Military Advisor, MacArthur had proposed a plan to protect the inland seas by emplacing heavy coastal guns at the en trance to the key straits leading into these waters. The War Department had approved this plan and sent 24 155-mm. guns (without fire control equipment) to the Philippine Commonwealth to carry out this program, scheduled for completion in April 1942. MacArthur now proposed to extend this plan to include northern Luzon and asked the War Department for 4 12-inch and 4 8-inch railway guns, 22 more 155- mm. guns, and 30 searchlights. When emplaced, he argued, these guns would present an enemy advancing on Manila with "fixed position gunfire, the lightest of which will (be of sufficient proportions to interfere with troop landings and the operations of lightly armored vessels." The letter was received in Washington at the beginning of December, too late to result in action.

            General MacArthur's request for authority to reorganize the Philippine Division as a triangular division had been readily granted. To accomplish this reorganization, MacArthur said he needed an infantry regiment, a field artillery headquarters and headquarters battery, two field artillery battalions, a reconnaissance troop, and a military police platoon for the division. The War Department agreed to provide these units and the staff began the detailed work necessary to select and ship them.

            MacArthur's plans for the Philippine Division were explained in a letter he wrote to the Chief of Staff on 28 October. He wished, he said, to have the division at war strength and trained intensively for combat. "It would be impolitic," he thought, "to increase the number of Philippine Scouts above the authorized 12,000, for all recruits would be taken from Philippine Army reservists to serve at higher rates of pay than the Philippine Army can pay." The only way, then, to increase the strength of the division was to secure an additional infantry regiment and two battalions of artillery from the United States. With these units and the American 31st Infantry, he could form two American combat teams in the Philippine Division. The Scouts thus released could be used to bring the 91st and 92d Coast Artillery Regiments of the Harbor Defenses up to strength, retain several small units already in existence, and provide station complements for Forts McKinley and Stotsenburg. The Philippine Division would then be free to train for combat and would be available "for instant use." "The entire plan," he told General Marshall, "will be placed in effect upon the arrival of the new regiment."

            MacArthur's plans included also the establishment of four major tactical commands, directly subordinate to USAFFE. On 2 October he requested authority, which was readily granted, to activate a headquarters and headquarters company for each "with average strength approximately those of Army Corps."  He also asked for army and corps troops to establish a balanced force, and for a field artillery brigade, a chemical company, three signal battalions, a medical supply depot, and a military police company, all at full strength and with complete organization and individual equipment. By the end of October he had requested almost 12,000 men: for the Philippine Division, 209 officers and 4,881 enlisted men; for army and corps troops, 340 officers and 6,392 enlisted men.

            During the next month MacArthur continued to ask for additional units and individual specialists, and by the middle of November the War Department had approved for transfer to Manila 1,312 officers, 25 nurses, and 18,047 enlisted men belonging to units. Individual specialists totaled 200 officers and 2,968 enlisted men. The units selected for this overseas movement, including the 34th Infantry for the Philippine Division, were scheduled for shipment, first for January 1942, but later, ironically, on 8 December 1941.

            These reinforcements and supplies were all intended for the regular U.S. Army establishment; requisitions for the Philippine Army were made and considered separately. His plan of induction had hardly been completed when MacArthur began to request from the War Department large amounts of supplies for his Philippine troops. During August alone he called for 84,500 Garand rifles (M1), 330 .30-caliber ma chine guns, 326 .50-caliber antiaircraft machine guns, 450 37-mm. guns, 217 81-mm. mortars, 288 75-mm. guns with high-speed adapters, and over 8,000 vehicles of all types for the ten Philippine Army divisions he planned to mobilize. On 18 September he was told that because of lend-lease commitments and production schedules it would not be possible to send most of these items. Especially unwelcome was the news that Garand rifles were not available and that the Philippine Army divisions would have to continue to use the Enfield and 1903's with which they were equipped.

            MacArthur nevertheless continued to request equipment for the Philippine Army, asking, on 10 September, for 125,000 steel helmets, as well as chemical, engineer, and signal equipment. A month later, the request for the helmets was approved. They would be shipped immediately and the other equipment would be shipped at a later date.

            Since the Philippine Army was not limited in size by law as was the U.S. Army, MacArthur was in the unique position of being able to raise as many troops as the War Department could equip. On 20 September he asked for "complete organizational equipment" for a number of army and corps units to be formed principally of Philippine Army personnel. Included were 2 155-mm. and 3 105-mm. howitzer regiments, a motorized battalion of 155-mm. guns, 3 antitank gun battalions, and service, signal, and medical units. These requests were approved and a shipping schedule established.

            Most disturbing was the shortage of light artillery and machine guns in the Philippine Army divisions. By the end of September the Philippine Army had only 48 75-mm. guns. At least 240 were required to equip the artillery regiments of the ten reserve divisions and another 36 for field artillery training centers. Also needed were 37-mm. guns for the antitank battalions and .50-caliber machine guns. Realizing that the supply of these guns was limited, MacArthur expressed a willingness to accept as substitutes obsolete models or smaller weapons. "Strongly recommend," he appealed to the Chief of Staff, "improvisation to the extent of providing substitute arrangement in spite of lowered efficiency for any types available in the United States."

            By mid-November, the War Department had taken action to ship 40 105-mm. howitzers to the Philippines. These weapons were to be given to U.S. Army units and would release to Philippine Army units a like number of 75's. In addition, 10 75-mm. pack howitzers were to be taken from the vital Canal Zone and 48 British 75-mm. guns and 123 .30-caliber machine guns from the equally important Hawaiian garrison for the Philippine Islands, an indication of the importance which the defense of the archipelago had acquired in the eyes of the War Department. From the United States itself would come 130 75-mm. guns, 35 37-mm. guns (M1916) and 14 .30-caliber machine guns.

            No action was taken until October to supply the thousands of vehicles MacArthur had requested. During that month a large number of jeeps, ambulances, trucks, and sedans became available and on the 15th the War Department released these vehicles for the Philippine Army, "subject to the availability of shipping.” A request for clothing for the Philippine Army was also approved, as was the equipment for ten 250-bed station hospitals and 180 sets of regimental infirmary equipment. An early requisition for 500,000 C rations and enough 55-gallon drums to hold 1,000,000 gallons of gasoline was filled during the summer. Strangely enough, the drums arrived filled although the gasoline had not been requested. This unexpected windfall proved extremely fortunate. A large portion of the gasoline was stored on Bataan and was most welcome during the campaign.

            The approval of requisitions and orders for shipment did not result in any immediate increase in the supplies of the Philippine Army. Time was required to order the stocks from depots and factories, pack and ship them to the port of embarkation, find the vessels to transport them, and finally get them to the Islands. In September, the Navy began sending cruiser escorts with Army transports and merchant ships on their voyages between Hawaii and Manila. This procedure frequently meant that the transports had to stop at Honolulu, some times reload, and then sail west at a speed equal to that of the slowest vessel in the convoy.

            The shipment of supplies was dependent upon the number of cargo vessels available to the Army. This number was never large and the Navy, for a time, threatened even this limited supply. In September the Navy announced its intention to convert three transports to escort carriers. General Marshall protested this decision vigorously, pointing out to the Chief of Naval Operations that it would delay the delivery of much-needed reinforcements to MacArthur by over two months. Despite the favorable outcome of this protest, a large back log of troops and approximately 1,100,000 tons of equipment destined for the Philip pines had piled up in U.S. ports or depots by November. A group of shipping experts, including representatives from the War Department General Staff, Office of the Quartermaster General, the Navy, and Maritime Commission, met on 10 November to discuss ways of breaking the shipping block. As a result of this meeting a shipping schedule was established which recognized the priority of the Philippines over Hawaiian defenses and advanced the troop movements scheduled for mid-January to 11 and 20 December. Altogether, nine vessels were assigned to the Manila route, to sail in November and December. They would bring to MacArthur one light and one heavy bombardment group, a pursuit group, one reconnaissance squadron, a regiment of infantry, a brigade of field artillery, two battalions of light artillery, together with ground and air service units. Had these vessels, the last of which was to leave the United States on 20 December, reached the Philippines the Japanese would have faced a far stronger force when they landed on Luzon.

 

Air Forces

            In July 1941 the air force in the Philippines was still a token force, unable to withstand "even a mildly determined and ill-equipped foe." Air Corps headquarters in Washington had been urging for some time that additional planes be sent to the Philippines and the Joint Board, early in 1940, had proposed an increase in air strength for the island garrison. The following July 1941 Maj. Gen. Henry H. Arnold, chief of the newly created Army Air Forces, came forward with the strongest proposal yet made for the reinforcement of the Philippines. This proposal called for the transfer to the Philippines of four heavy bombardment groups, consisting of 212 aircraft with 68 in reserve, and two pursuit groups of 130 planes each. These planes, wrote Brig. Gen. Carl Spaatz, chief of the Air Staff, would not be used for an offensive mission, but to maintain "a strategical defensive in Asia.

            General Arnold's recommendations, approved in August, were not easily carried out. To have raised that number of planes in the summer of 1941 would have meant stripping the fields in the United States as well as all other overseas bases. Moreover, many of the heavy bombers were still on the production lines. What could be scraped together was shipped immediately and by mid-August General Gerow reported to the Chief of Staff that thirty-one modern fighters of the P-40 type were on their way. Meanwhile General Arnold made arrangements to send fifty more directly from the factory. These, too, were soon on their way and by 2 October had arrived in the Philippines.

            Some weeks earlier a historic flight of nine Flying Fortresses had reached Manila by air. These planes were part of the 19th Bombardment Group (H), which had been selected for transfer to the Far East. After a flight from Hamilton Field near San Francisco, the Group's 14th Squadron, under Maj. Emmett O'Donnell, Jr., left Hickam Field in Hawaii on 5 September for Clark Field via Midway, Wake, Port Moresby, and Darwin. This pioneering 10,000-mile flight, almost all of it over water, was successfully concluded a week later, establishing the fact that the Philippines could be reinforced by air. But the Midway-Wake reinforced by air route could not be considered safe in the event of war with Japan since it passed over the mandated islands and work was begun after October to develop a South Pacific ferry route.

            Once the pioneering flight had been successfully concluded, all heavy bombers sent to the Philippines went by air via the Central Pacific route. On 9 September, General Marshall told MacArthur that two additional squadrons of the 19th Group the 30th and 93d -- would leave the next month. At that time the ground echelon of the two squadrons and the headquarters sailed from San Francisco. The air echelon of twenty-six B-17's followed soon after. By 22 October these planes had arrived at Hickam Field in Hawaii. After a short stopover they flew on to Clark Field where all but two reported on 4 November; the other two followed soon after.

            The flight of the 30th and 93d Squadrons was one in a scheduled series which called for the shipment of 33 heavy bombers in December, 51 in January 1942, and 46 more in February. By March 1942 the War Department planned to have 165 heavy bombers in the Philippines.

            Scheduled for shipment after the 19th Bombardment Group was the 7th. The ground echelon reached Hawaii late in November and was held there until naval escort could be secured. The air echelon, scheduled to fly to the Philippines via the Midway route during late November and early December, had completed only the first leg of the journey before war came.

            In addition to heavy bombers, MacArthur was also promised a light bombardment group of three combat squadrons. Selected for shipment was the 27th Bombardment Group (L). The Air Corps experienced some difficulty in securing the 52 A-24's for this group but by early November the planes had been collected. The pilots and ground personnel reached the Philippines during November but the A 24's, loaded on a separate transport, were held at Hawaii with the ground echelon of the 7th Bombardment Group and failed to reach their destination.

            At the end of November General Marshall summarized for the Secretary of War the air reinforcements already shipped or scheduled for shipment to the Philippines. At that time, he noted, there were 35 B-17's already in the Islands and 52 A-24's were due there -- they never arrived -- on the 30th. Fifty P-40s had reached MacArthur in September, Marshall explained to Stimson, thus giving him a total of 81 modern fighters. In addition, 24 P-40s had left San Francisco on 19 October, and 40 more on 9 November. By 31 December, General Marshall estimated, the Philippines should have a total of 240 fighters of the latest type.

            By now the War Department was fully committed to an all-out effort to strengthen the air defense of the Philippines. General Arnold, in a letter to the commander of the Hawaiian Air Force on 1 December, ex pressed this view when he wrote: "We must get every B-17 available to the Philippines as soon as possible." His statement was not an exaggeration. On the outbreak of war there were 913 U. S. Army aircraft scattered among the numerous overseas bases. This number of aircraft included 61 heavy, 157 medium, and 59 light bombers and 636 fighters. More than half of the total of heavy bombers and one sixth of the fighters were already in the Philippines. Within a few months this number would have been raised considerably.

            The arrival of the bombers and additional pursuit planes, with the promise of more to come, led to a reorganization of the air forces in the Philippines. Early in the fall of 1941 General MacArthur had asked for Maj. Gen. Lewis H. Brereton, a senior air officer, as his air commander. This request was approved and early in October Brereton was relieved of command of the Third Air Force and called to Washington. There, in a series of conferences at Army Air Force headquarters, the form of a new air organization, to be called the Far East Air Force, was drawn up."

            General Brereton arrived in the Philippines on 3 November. He saw MacArthur that same day, and gave him the latest views about reinforcements and developments within the War Department. By the middle of the month the reorganization of the air forces had been accomplished and a short time later MacArthur told Marshall, "Brereton has taken hold in an excellent manner."

            The newly activated Far East Air Force, with headquarters at Nielson Field in Manila,. included the V Bomber Command, the V Interceptor Command, and the Far East Service Command. The main element of the bomber command, led by Lt. Col. Eugene L. Eubank, was the 19th Bombardment Group with its thirty-five B-17's. Only two squadrons of the original group, the 30th and 93d, were in the Philippines. On 16 November, the 28th Squadron, a medium unit, was also assigned to the group and equipped with B-17's and on 2 December the 14th Squadron joined the group. In addition to heavy units, the bomber command also contained the ground echelon of the 27th Bombardment Group, whose fifty two A-24's were delayed at Hawaii and never reached the Philippines.

            The V Interceptor Command, first under Brig. Gen. Henry B. Clagett and later Col. Harold H. George, consisted initially of the 24th Pursuit Group with the 3d, 17th, and 20th Squadrons. When, in November, the 21st and 34th Squadrons arrived in Manila, they were attached to the group, pending arrival of their own organization (which never arrived). The Interceptor Command was considerably modernized during the fall of 1941 and by 1 December all but one of its pursuit squadrons were equipped with P-40's."

            The prerequisites for an effective air force are not only modem and sufficiently numerous attack and interceptor aircraft, but adequate fields, maintenance and repair facilities, and the antiaircraft artillery and air warning service to defend these installations. The lack of fields in the Philippines was recognized early. Within eighty miles of Manila there were six fields suitable for pursuit planes and only one, Clark, for heavy bombers. Outside of Luzon were six additional Army fields, useful principally for dispersal. More were needed to base the large number of modern aircraft due to arrive before the end of the year. In August General MacArthur was allotted $2,213,000 for airfield development and in October $7,000,000 more. The largest part of these funds was to be expended on Luzon, at Nichols and Clark Fields, with auxiliary fields at Iba, on the Zambales coast west of Clark, and various points on northern Luzon.

            In mid-November MacArthur decided to establish a heavy bomber base in north em Mindanao at Del Monte, which since September had had a strip capable of landing B-17's. This decision was based on the belief that heavy bombers on Luzon would be subject to attack and that they should therefore be moved south, out of reach of the enemy. His plans, MacArthur told the Chief of Staff on 29 November, called ultimately for a bomber base in the Visayas, but until such a base was completed he expected to use the field at Del Monte. Work on Del Monte Field was rushed and by the beginning of December it was able to accommodate heavy bombers.

            Despite the arrival of reinforcements and the airfield construction program, the air defense system remained inadequate because of the shortage of antiaircraft artillery and aircraft warning equipment. MacArthur had requested warning equipment in September and had at that time presented a plan for the establishment of an air warning service. The War Department had approved the project and by mid September three radar sets had been shipped with three more scheduled for shipment in October. In addition, $190,000 was allotted for aircraft warning construction, with an additional $200,000 to be included in the supplemental estimate for the fiscal year 1942 for the construction of three detector stations and one information center.

            The one air warning service company of 200 men in the Philippines was entirely inadequate to the needs of the Far East Air Force. In November General Arnold recommended, and the Chief of Staff approved, the shipment of an aircraft warning service battalion to the Philippines. The 557th Air Warning Battalion was organized in the United States and on 6 December 1941 arrived in San Francisco, too late for shipment to the Philippines.

            When war came there were seven radar sets in the Islands, but only two had been set up and were in operation. In the absence of the necessary equipment and personnel, USAFFE had organized a make shift air warning service. Native air watchers stationed at strategic points reported plane movements by telephone or telegraph to the interceptor command at Nielson Field, which in turn relayed the information to Clark. It was this primitive system, augmented by the radar sets established at Iba and outside Manila, that was in operation when war came.

            That other prerequisite for a balanced air force, antiaircraft artillery, was also slow in reaching the Far East. In the Islands when MacArthur assumed command was the 60th Coast Artillery (AA). In anticipation of heavy reinforcements he organized in August the Philippine Coast Artillery Command with Maj. Gen. George F. Moore in command. Plans provided for an area defense of the four fortified islands in Manila Bay (Corregidor, El Fraile, Caballo, and Carabao) and the southern tip of Bataan. One antiaircraft gun battery with a platoon of searchlights was stationed at Fort Wint in Sable Bay. When the 200th Coast Artillery (AA) arrived in September it was ordered to Fort Stotsenburg to protect Clark Field. Both antiaircraft units were equipped with 3-inch and 37-mm. guns, .50-caliber machine guns, and 60-inch Sperry searchlights. The 3-inchers were an old model with a vertical range of 27,000 feet.

            The two antiaircraft units alone obviously could not defend the fields of the rapidly growing Far East Air Force, let alone meet civilian defense requirements. Of necessity, therefore, the air defenses included only the Manila Bay area and Clark Field; all other installations were left virtually without defense against air attack. General Brereton was rightly concerned about the lack of antiaircraft defense and observed, even before he left Washington, that sending heavy bombers to the Philippines without providing proper antiaircraft protection would probably be suicide. But there was little that could be done in the short time available. Maj. Gen. Joseph A. Green, Chief of Coast Artillery, suggested that elements of the Harbor Defenses be reassigned to antiaircraft duty, but the proposal was rejected.

            The War Department and the Air Forces continued to show concern over the anti aircraft defenses of the Islands, about which they did not have too clear a picture. A radio to General MacArthur for information elicited the reply on 21 November that an increase in armament was required and that detailed plans were being forwarded by mail. These plans were sent on 1 December but even before then War Plans had recommended the dispatch of three antiaircraft regiments and two antiaircraft brigade headquarters to the Philippines. These units were to utilize the equipment then in the Islands, thus reducing shipping requirements. Action on this proposal was begun at the end of November, when time had almost run out. When war came, the antiaircraft defenses in the Philippines were little better than they had been three months earlier.

 

Naval Forces

            Naval forces assigned to the defense of the Philippines were organized into the U.S. Asiatic Fleet. Normally stationed in Asiatic waters, this fleet by mid-1941 was based in Manila with headquarters in the Marsman Building. Admiral Thomas C. Hart commanded the fleet and reported directly to the Chief of Naval Operations in Washington. The 16th Naval District headquarters was at Cavite on the south shore of Manila .Bay.

            Hart's fleet consisted of the flagship, the heavy cruiser Houston; 1 light cruiser; 3 destroyer divisions with 13 overage four stack, flush-deck destroyers of World War I vintage; and 17 submarines. The under water craft were organized into Submarine Squadron 20, supported by tenders and 1 rescue vessel. Air elements of the fleet were under Patrol Wing 10, composed of 24 PBY's and 4 seaplane tenders. Patrol and miscellaneous craft included 1 gunboats, 1 yacht, 6 large minesweepers, 2 tankers, and 1 ocean-going tug. Also a part of the fleet but stationed in Shanghai was the U.S. Marine Corps' regiment, the 4th Marines.

            Obviously such a force was not capable of withstanding even momentarily the Japanese Combined Fleet, and Admiral Hart had authority to retire to bases in the Indian Ocean if necessary. From the small detachments of sailors in the 16th Naval District little more could be expected than assistance in protecting local naval installations. The 4th Marines could be of considerable help in the defense of the Philippines if it could be taken out of China in time.

            Although Allied naval forces in the Far East were not expected to provide direct support for the Philippine Islands in case of war with Japan, they would, if Japan attacked them, fight the common enemy. The British, in May 1941, had in Far Eastern waters 1 battleship, 1 aircraft carrier, 4 heavy and 13 light cruisers, and a few destroyers. The Dutch could contribute 3 light cruisers, 1 destroyers, and 15 submarines. By December of that year the British Fleet in the Far East had been augmented by 3 battleships and 3 destroyers.

            The bulk of American naval strength in the Pacific was assigned to the Pacific Fleet. Before 1940 the main body of the Pacific Fleet had been based on the west coast of the United States. In May 1940 the Navy announced that the fleet, which had sailed to Hawaiian waters for war games, would be based at Pearl Harbor indefinitely. This decision had been made by President Roosevelt in the belief that the presence of the fleet would act as a deterrent to Japan. A year later the Pacific Fleet, now based at Pearl Harbor and commanded by Admiral Husband E. Kimmel, consisted of 9 battle ships, 3 aircraft carriers, 1 2 heavy and 8 light cruisers, 50 destroyers, 33 submarines, and 100 patrol bombers. The strength of this fleet was substantially the same on 1 December 1941 when the attack on Pearl Harbor came.

            Although Admiral Hart had been told in May 1941 that he would receive no additional surface ships for his fleet, he was able to do much to put his force in readiness for action before the outbreak of war. Beginning in July, three to six PBY's maintained constant watch along the southern boundary of the archipelago and later linked with the Dutch Navy's air patrol north of Borneo. The mining of Manila and Sable Bays was pushed through to completion, in co-operation with the Army, by the end of August and provided security against all but submarines and shallow-draft surface craft. The Navy's base at Mariveles, on the southern tip of Bataan, was rapidly built up and on 22 July the drydock Dewey was moved there from Olongapo. By the end of the month the base at Olongapo was being used by the navy only as an auxiliary air base and as a station for Marines and some naval personnel.

            In the six months before war the Asiatic Fleet was reinforced strongly in underwater craft. On 8 November 8 large submarines of the Pacific Fleet arrived in Manila and on the 24th 4 more, accompanied by the tender Holland, joined the fleet. Together with those already assigned, Admiral Hart now had 29 submarines.

            The fleet was further reinforced in September by six motor torpedo boats, considered ideally suited for operation in Philippine waters. Twelve had been allocated but the remainder were never received. In addition, General MacArthur told Admiral Hart that he would mobilize the naval component of the Philippine Army, with. its two motor torpedo boats, whenever Hart desired.

            Early in November the Navy Department directed Hart to withdraw the marines and the gunboats from China, a move which the admiral had proposed earlier. Five of the gunboats made the trip from China to Manila successfully, leaving the Wake, stripped and ready for demolition it was later seized by the Japanese and the Tutuila for the Chinese. Two President liners were chartered and sent to Shanghai where the majority of the 4th Marines was stationed; the detachments at Pekin and Tientsin were to load at Chinwangtao. On 21 and 28 November the regiment, with attached naval personnel and civilian refugees, embarked on the two vessels for the Philippines. Arriving on 30 November and 1 December, the regiment was assigned the mission of guarding the naval stations on Luzon, particularly the new base at Mariveles. One of the vessels, the President Harrison, started back to Chinwangtao to embark the remaining marines but fell into Japanese hands. With its weapons and equipment, and consisting of long service men and a full complement of regular officers, the 4th Marines (strength, 750 men) formed a valuable addition to the infantry force in the Islands.

 

Summary

            In a letter prepared on 5 December 1941. but never sent, General Marshall outlined for General MacArthur what had been and was being done to strengthen USAFFE. "Reinforcements and equipment already approved," he said, "require over 1,000,000 ship tons." Fifty-five ships had already been obtained and approximately 100,000 ship tons of supplies were en route, with twice this amount ready for immediate shipment to ports of embarkation. Requests for equipment for the Philippine Army, except those for the M1 rifle, had been approved, and uncontrolled items of supply were being shipped as rapidly as they could be assembled and loaded on ships. "Not only will you receive soon all your supporting light artillery [130 75-mm. guns]," Marshall told MacArthur, "but 48 155-mm. howitzers and 24 155-mm. guns for corps and army artillery." Except for certain types of ammunition, the defense reserve for the U.S. Army forces in the Philippines would be completed in April 1942, and for the Philippine Army by July of that year. Three semimobile antiaircraft artillery regiments were scheduled to leave the United States soon, but the 90-mm. antiaircraft gun could not be sent since it had not yet been fully tested. A sum of $269,000,000 had been requested from Congress for the support of the Philippine Army, and early passage of such legislation was expected. "I assure you," Marshall closed, "of my purpose to meet to the fullest extent possible your recommendations for personnel and equipment necessary to defend the Philippines.”

            The last vessels carrying supplies to the Philippines were assembled in convoy in Hawaii and on 1 December were still on the high seas. In the convoy were the 52 dive bombers of the 27th Bombardment Group, 18 P-40's, 340 motor vehicles, 48 75-mm. guns, 3,500,000 rounds of .30 and .50 caliber ammunition, 600 tons of bombs, 9,000 drums of aviation fuel, and other heavy equipment and supplies. Also aboard were the two light field artillery battalions and the ground echelon of the 7th Bombardment Group (H).

            The military force in the Islands at the beginning of December, while not as large as MacArthur soon hoped to have, was considerably larger than it had been five months earlier. The air force had been reorganized, modem bombers and fighters had been brought in, and a start made on the creation of a balanced force. The strength of air force troops on 30 November was 5,609, more than double the July strength. The Far East Air Force had more than 250 aircraft, concentrated largely on Luzon. Less than half of these planes were suitable for combat, and much of the equipment was still in ports of embarkation. There were 35 B-17's at Clark Field and 107 P-40's at various fields on Luzon. A primitive aircraft warning system was in operation, and an antiaircraft artillery regiment was stationed at Clark Field. Much remained to be done, but the Philippines could boast a stronger air complement of modem combat aircraft on 1 December than any other base, including Hawaii and Panama.

            Naval forces assigned to the Asiatic Fleet had also been considerably strengthened. By 1 December this fleet consisted of 1 heavy and 2 light cruisers, 13 old destroyers, 32 PBY's, 6 gunboats, 6 motor torpedo boats, and miscellaneous vessels. Its strongest element was the submarine force of 29 underwater craft.

            Ground forces in the Philippines had been considerably reinforced, too, in the few months since General MacArthur had assumed command. The ten reserve divisions of the Philippine Army had been two-thirds mobilized and although poorly equipped and trained represented a military force of some size. Within a week after the outbreak of war it numbered over 100,000 men. The U.S. Army garrison in the Islands had been increased by 8,563 men since 31 July. The number of Philippine Scouts, fixed by law, remained the same, approximately 12,000. The number of American enlisted men increased by 7,473 and officers by 1,070. The largest proportionate increase was among service troops. As of 31 July, 1,836 men were assigned to service detachments; four months later the number had increased to 4,268. During this same period, the number of Air Corps troops had increased from 2,407 to 5,609.  Total strength of the entire U.S. Army garrison on 30 November 1941 was 31,095 officers and enlisted men.

            In the four months since General MacArthur's assumption of command, the flow of men and supplies to the Philippines had increased tremendously and all preparations for war had been pushed actively and aggressively. Time was running out rapidly, but at the end of November many still thought it would be several months before the Japanese struck. The month of April 1942 was commonly accepted as the critical date and most plans were based on that date. By 1 December MacArthur had organized his forces, but still needed much to place them on a war footing. Most of his requests had been approved by the War Department and men and supplies were already on their way or at San Francisco awaiting shipment. The record of accomplishment was a heartening one and justified the optimism which prevailed in Washington and in the Philippines over the capacity of the Philippine garrison to withstand a Japanese attack.

 

The First Days of the War

Chapter 5

            For those on the west side of the international date line, the "date which will live in infamy" came on 8 December 1941. Few responsible military or naval men had believed that the Japanese would be able to strike in more than one place. The number and diversity of their attacks took the Allies completely by surprise. During the early morning hours of the 8th, Japanese naval and air forces struck almost simultaneously at Kota Bharu in British Malaya (0140), Singora, just across the border in Thailand (0305), Singapore (0610), Guam (0805), Hong Kong (0900), Wake, and the Philippines.

            Landing operations began almost immediately. By dawn, Japanese forces were in possession of Shanghai. Even as the first bombs were dropping on Hong Kong, Japanese troops were on their way into the leased territory. By the end of that day they were only a few miles from Kowloon, which they took on the 13th. Hong Kong fell on Christmas Day.

            Within an hour after the first bombardment of Kota Bharu, Japanese troops from Indochina began to land on the beaches against bitter opposition. The same day, when the main force of the 25th Army arrived, the beachhead was secured. The landings at Singora were unopposed. There, the troops marched down the east coast of the Kra Isthmus, while one division crossed the Thailand-British Malay border and moved down the west coast. Thus began a two-month campaign which ended with the fall of Singapore on 15 February.

            On Guam the air attacks continued for two days. Finally, at dawn on the 10th, the South Seas Detachment and supporting naval units landed on the island. A few hours later, the garrison there surrendered. This was the first American possession to fall into Japanese hands. At Wake Island, the Marine detachment under Maj. James P. S. Devereux was better prepared for the enemy and offered heroic resistance. The first attempt to land was beaten off and the Japanese returned to Kwajalein to lick their wounds and collect more troops for the next attempt. They were back at Wake on the 22d and the next morning landed in force. That same day the garrison surrendered.

            The fall of Wake and Guam cut the line of communications between Hawaii and the Philippines and left the United States with no Central Pacific base west of Midway, 4,500 miles from Manila. But even before this, on the first day of war, the Japanese attack on Pearl Harbor had destroyed the Battle Force of the Pacific Fleet and nullified all plans to come to the aid of the Philippines.

            East of the date line, Vice Adm. C. Nagumo's Pearl Harbor Striking Force of six carriers reached its launching position 200 miles north of Oahu exactly on schedule, at 0600 on the morning of 1 December (0100 of the 8th, Tokyo time ). Two Jakes (Zero type reconnaissance planes), which had taken off at 0530 to reconnoiter, returned with the report that, except for the richest prize, the three carriers, the entire Pacific Fleet was in port. Pilots of the first Air Fleet, amidst shouts of "banzai" from their comrades, took off from the flight decks and climbed above the overcast into a magnificent sunrise. At 0715, while "Pearl Harbor was still asleep in the morning mist," the Japanese planes came in over the island. Five minutes later, just an hour before Nomura presented his government's reply to Mr. Hull, they dropped their first bombs.

            The next two hours of that Sabbath morning in Hawaii were a nightmare. Bombs and torpedoes dropped everywhere, on the ships in the harbor, on Army installations, on depots, and other targets. Dive bombers machine-gunned planes on the ground and men on the ships. Within a half hour every battleship at Pearl Harbor had been badly damaged.

            Hickam and Wheeler Fields were struck in the first attacks. The Army planes, parked in close order, wing tip to wing tip, made perfect targets. By ten o'clock the raid was over and the last Japanese planes had returned to their carriers, leaving behind them death and destruction. Tactical surprise had been as complete as strategical surprise.

            The Japanese pilots knew exactly what to go after. Though there were ninety four naval vessels in the harbor they concentrated on the Battle Force, sinking 3 battleships, capsizing 1, and damaging 4 more. In addition to the battleships, 3 light cruisers, 3 destroyers, and miscellaneous vessels were badly damaged. Ninety-two naval planes were lost and 31 damaged. The Army lost a total of 96 planes, including those destroyed in depots and those later stripped for parts. Army and Navy installations were badly hit. Fortunately, the Japanese failed to destroy the repair shops at Pearl Harbor or the oil tanks, filled to capacity. The carriers, then at sea, escaped the attack altogether. American casualties for the day were 2,280 men killed and 1,109 wounded. The Japanese lost only 29 aircraft and 5 midget submarines. "The astoundingly disproportionate extent of losses," concluded the Joint Committee which investigated the attack, "marks the greatest military and naval disaster in our Nation's history.

            With this smashing blow, the Japanese made obsolete the carefully prepared plans of defense in the event of war in the Pacific. The RAINBOW plan called for the progressive movement of the Pacific Fleet across the Central Pacific by the capture of the Caroline and Marshall Islands and the establishment of an advanced base at Truk. The fleet would thus open the line of communications, establish superiority in the western Pacific, and come to the relief of the Philippine Islands. Along this protected line of communications would flow the supplies and men that would enable the Philippine garrison to beat back any Japanese effort to seize the Islands. By 1000 on the morning of 7 December, the force required to put RAINBOW into effect, the Battle Force of the Pacific Fleet, lay in ruins in Pearl Harbor. The Philippines were isolated, cut off from the nearest base 5,000 miles away, even before they had felt the first blow of the war. Their only hope now lay with the Far East Air Force and the Asiatic Fleet.

 

The Attack on Clark Field

            The duty officer at Asiatic Fleet head quarters in the Marsman Building in Manila on the night of 7-8 December (Philippine time) was Lt. Col. William T. Clement, USMC. At 0230 of the 8th (0800, 7 December, Pearl Harbor time), the operator at the Navy station intercepted the startling message, "Air Raid on Pearl Harbor. This is no drill." Recognizing the technique of the sender, an old friend stationed at Pearl Harbor, the operator brought the message to Colonel Clement. Within a half hour, it was in Admiral Hart's hands. He broadcast the news to the fleet immediately, and then, with his chief of staff, hurried to his office.

            Shortly after 0330 General Sutherland received the news of the Pearl Harbor attack, not from the Navy but from commercial broadcasts. He passed the news on to MacArthur over the private wire to the general's penthouse apartment in the Manila Hotel, then notified all commanders that a state of war existed with Japan. Troops were ordered to battle position immediately.

            At Clark Field the news flash about Pearl Harbor was also picked up from commercial broadcasts. The operator immediately notified headquarters at the field and all units were alerted. "I knew," Brereton later wrote, "we could expect an attack from the Japs any time after daylight." Before leaving for MacArthur's headquarters, he ordered Colonel Eubank, the bomber commander at Clark Field, to come down to Manila at once. At about 0500 in the morning Brereton was waiting outside MacArthur's office for orders.

            By breakfast, the news of the attack on Pearl Harbor had reached all ranks. The men had for so long accepted the fact that war with Japan might come that the event, itself was an anticlimax. There was no cheering and no demonstration, but "a grim, thoughtful silence." War with Japan was not, for the American and Philippine troops, a remote war across a wide ocean. It was close and immediate.

 

Prologue to Attack

            On Formosa airfields, 500 miles away, Japanese Army and Navy pilots were standing by, their planes gassed and ready to take off for Luzon, when the first news of Pearl Harbor reached Manila. Around midnight of the 7th dense clouds of heavy fog had closed in on the island, blanketing airfields and preventing the scheduled take offs at dawn.

            This unforeseen development filled the Japanese commanders with nervous apprehension. The timetable for the attack was extremely close and left little leeway. As the early morning hours rolled by, anxiety increased. By this time, the Japanese believed, the American high command in the Philippines would have received news of Pearl Harbor and either sent the Far East Air Force southward or set up an effective defense against the impending raid. All hope of surprise would be lost.

            Even more frightening was the possibility that this delay would enable the heavy bombers of the Far East Air Force to attack the planes lined up on Formosa fields. In deed, at 0800, the Japanese intercepted an American radio message which they interpreted as meaning that such an attack would come off in two hours. At 1010 a Japanese plane mistakenly reported B-17's approaching Formosa and the frightened Japanese began passing out gas masks.

            Japanese fears of an American attack against Formosa were not without foundation. Such plans had already been made and target data had been prepared. The objective folders were far from complete, however, and lacked calibrated bomb-target maps and bomb release lines for given speeds and altitudes. "But we had some thing complete enough," thought Capt. Allison Ind, a Far East Air Force intelligence officer, "to make this bombing mission a very far cry from the blind stab it would have had to be otherwise."

            On his first visit to USAFFE headquarters about 0500, General Brereton had been unable to see MacArthur and had talked with Sutherland. At that time he had requested permission to carry out a daylight attack against Formosa. MacArthur's chief of staff had told him to go ahead with the necessary preparations, but to wait for MacArthur's authorization before starting the attack. Brereton returned to his headquarters at Nielson Field, where he talked with Colonel Eubank, who had just flown down from Clark Field. Orders were issued to get the B-17's ready. At about 0715 Brereton apparently went to MacArthur's head quarters again to request permission to attack Formosa. Again he was told by Sutherland to stand by for orders.

            About this time the Far 'East Air Force commander received a transoceanic telephone call from his air force chief, General Arnold. Brereton explained what he was trying to do, and Arnold told him what had happened at Pearl Harbor, so that, as he later explained, Brereton would not be caught in the same way and have his "entire air force destroyed."

            By this time, reports of enemy flights were being received at air force headquarters and planes of the Interceptor Command were sent up. Around 0800 the heavy bombers at Clark Field were ordered aloft on patrol, without bombs, to avoid being caught on the ground.

            At 1000 Brereton renewed his request to take offensive action. "I personally called General Sutherland," he says, "and informed him... that if Clark Field was attacked successfully we would be unable to operate offensively with the bombers." Again the request was denied. Ten minutes later, Colonel Eubank started back to Clark Field with instructions to dispatch a photographic reconnaissance mission immediately to southern Formosa.

            No sooner had those orders been issued than Brereton received a telephone call from General MacArthur. He told MacArthur that since Clark Field had not yet been attacked, he would hold the bombers in readiness until he received reports from the reconnaissance mission already authorized. They agreed that if no reports were received, the bombers would attack Formosa late that afternoon. MacArthur left to Brereton "the decision for offensive action."

            Brereton called in his staff and told them of his conversation with MacArthur. Orders were then dispatched to Clark Field to call in the heavy bombers. Three were to be readied for the photo reconnaissance mission; the others were to be briefed for offensive missions. At 1120 Field Order No. 1 of the Far East Air Force was sent by teletype to Clark Field. It confirmed Brereton's instructions to Eubank, given at 1045, to attack southern Formosa with two heavy bombardment squadrons "at the latest daylight hour today that visibility will permit." By 1130 the bomber were back on the field, being loaded with 100- and 300-pound bombs; the fighters had also returned to base for refueling. At 1156 Brereton gave Sutherland a full report of the situation over the telephone, and informed him that he planned to attack Formosa fields late that afternoon.

            General Sutherland's account of the proposed raid on Formosa differs from the air force story. On one occasion, Sutherland recollected that there had been some plan to bomb Formosa on 8 December but that Brereton said he had to have the photos first." On another occasion Sutherland took the opposite and more consistent position that when Brereton asked for permission to attack Formosa, he, Sutherland, had ordered a reconnaissance first.

            General MacArthur's statements do not throw any light on this question. He had received word from Washington early that morning (at 0530) that hostilities with Japan had begun, and that he was to carry out the tasks assigned in RAINBOW.

            Brereton's surmise, therefore, that he was not permitted at first to attack Formosa because MacArthur was under orders not to attack unless attacked first and that the Pearl Harbor attack "might not have been construed as an overt act against the Philippines" must be dismissed. MacArthur had authority to act, and RAINBOW specifically assigned as one of his missions, air raids against Japanese forces and installations within tactical operating radius of available bases."

            General Brereton's surmise, however, was not entirely without foundation. It was evidently based on the 21 November warning from the War Department. That warning had stated that "if hostilities can not be avoided the United States desires that Japan commit the first overt act." The War Department had been careful, however, not to restrict MacArthur's freedom of action, and had authorized him in the same message to "undertake such reconnaissance and other measures as you deem necessary" prior to hostile Japanese action. In the event of war he was to execute the tasks assigned in RAINBOW.

            In the period between the receipt of this message and the outbreak of hostilities, the B 17's had flown reconnaissance missions north of Luzon in the direction of Formosa. Their search sectors, according to General Sutherland, reached to "the southern edge of Formosa with one segment of the pie running up the east coast of the island a little way." But General Brereton declares he was instructed by MacArthur to limit the reconnaissance to “two thirds of the distance between North Luzon and South Formosa.” Later, he says, he secured permission to extend the northern limit of the search sector to the international treaty boundary between the Philippines and Formosa. On the basis of Sutherlands statement, then, it was possible to conduct a partial reconnaissance of Formosa before the war; according to Brereton there was no prewar reconnaissance on MacArthur’s orders.

            On Brereton's proposal to bomb Formosa, General MacArthur expressed himself most clearly. When Brereton's diaries were published in 1946, MacArthur released a statement to the press recounting in full his recollection of the events of 8 December 1941. The press release, issued on 21 September 1946, read:

            General Brereton never recommended an attack on Formosa to me and I know nothing of such a recommendation having been made.... That it must have been of a most nebulous and superficial character, as no official record exists of it at headquarters. That such a proposal, if intended seriously, should have been made to me in person by him; that he never has spoken of the matter to me either before or after the Clark Field attack. That an attack on Formosa with its heavy concentrations by his small bomber force without fighter support, which because of the great distance involved, was impossible, would have had no chance of success.

            On 8 December, in summarizing the results of the Japanese attack, MacArthur had told the War Department: "I am launching a heavy bombardment counterattack tomorrow morning on enemy airdromes in southern Formosa.” It is evident, then, that MacArthur himself planned, by the afternoon or evening of the 8th, to execute an attack against Formosa with the remaining B-17's.

            Faced with these conflicting accounts, the historian can be sure only of five facts: (1) That an attack against Formosa was proposed; (2) that such an attack was deferred in favor of a photo reconnaissance mission requested either by Brereton or Sutherland; (3) that about 1100 on 8 December a strike against Formosa, to take place that day, was finally authorized; (4) that the heavy bombers were back on Clark Field after 1130 on the morning of 8 December; and (5) that MacArthur planned an attack against Formosa for the morning of 9 December.

 

The Attack

            The Japanese, fearing an air attack against Formosa, had meanwhile made haste to get their planes off the ground. The fog, which had grounded the 11th Air Fleet, had lifted to the east at dawn, permitting twenty-five twin-engine Army bombers to take off for Luzon.

            Shortly before 0900 the Japanese Army bombers were reported by the aircraft warning service on Luzon to be heading south over Lingayen Gulf in the direction of Manila. It was probably this report that sent the B-17's at Clark Field aloft without bombs. The 20th Pursuit Squadron at Clark took off to intercept the strike and the 17th Pursuit Squadron rose from Nichols Field to cover Clark. But the Japanese Army planes, limited to targets north of the 16th latitude, turned east as they approached Lingayen Gulf. One group struck Tuguegarao at about 0930 while another concentrated on barracks and other installations at Baguio, the summer capital of the Commonwealth, where Quezon was staying at this time. The Japanese bombers returned to base without having sighted any American aircraft. Far East Air Force reports between 1000. and 1030 of a flight of enemy bombers, first in the Cagayan valley, and then "turned around and proceeding north," apparently referred to these Japanese Army planes.

            By the time the false report of approaching B-17's had been received on Formosa, the fog had lifted sufficiently to permit the naval planes of the 11th Air Fleet to take off. At 1015, a force of 108 twin-engine bombers escorted by eighty-four Zeros set out for Clark and Iba. Only the very best and most experienced pilots had been assigned to this important mission.

            As the Japanese planes approached northern Luzon, the airborne American aircraft received the all-clear signal and were instructed to land. By 1130 nearly all the planes were back at their bases. The two squadrons of B-17's were on Clark Field, loading with gas and bombs for the raid against Formosa. The 20th Pursuit Squadron was also at Clark after its vain attempt to intercept the last Japanese flight. At Nichols, the 11th Pursuit Squadron, which had been covering Clark, was landing to refuel. The 3d and 34th Pursuit Squadrons were standing by at Iba and Del Carmen.

            Shortly before 1130, reports of an approaching enemy formation began coming in to the plotting board at Nielson. In addition to radar reports, almost every postmaster along the northwest coast of Luzon reported the high-flying enemy bombers to the air warning center by telephone or telegraph. Colonel George, chief of staff of the Interceptor Command, was in the plotting room when the reports were coming in, and predicted "that the objective of this formidable formation was Clark Field."

            At about 1145, according to Col. Alexander H. Campbell, the aircraft warning officer, a warning message went out to Clark Field by teletype. If the message did not get through, as is frequently asserted, this fact was not known to the officers in the plotting room at Nielson. It is asserted also that an attempt to warn the field by radio over the Far East Air Force net was made, but with no success. The reason for this failure can only be guessed. Col. James V. Collier, a G-3 officer in USAFFE headquarters, later stated, "The radio operator had left his station to go to lunch," and another source states, "Radio reception was drowned by static which the Japanese probably caused by systematic jamming of the frequencies.” Apparently other available means of communication, such as the long distance telephone lines, telegraph, and the command radio net to Fort Stotsenburg, were not used or thought of. Colonel Campbell did get a telephone message through to Clark Field and talked with an unknown junior officer there. This officer intended, said Campbell, to give the base commander or the operations officer the message at the earliest opportunity.

            Meanwhile, Colonel George at Nielson had dispersed his fighters to meet the attack. The 34th Squadron was ordered to cover Clark Field; the 17th, the Bataan peninsula; and the 21st, the Manila area. The 3d Squadron at Iba was dispatched to intercept a reported enemy formation over the South China Sea. At Clark Field, two squadrons of B-17's and the 20th Pursuit Squadron were still on the ground. Some time shortly before 1145 the fighters were ordered aloft as soon as refueling was completed to cover their own base.

            The 3d Pursuit Squadron took off from Iba to intercept the enemy flight over the South China Sea. A thick haze of dust prevented the 34th at Del Carmen from taking off, and at 1215 the 20th Pursuit Squadron at Clark, whose planes had just completed refueling, made ready to take off.

            At that moment the first formation of Japanese bombers appeared over Clark Field. All but one of the B-17's was lined t up on the field and the fighters were just getting ready to take off. After the warning of the Pearl Harbor attack, and after the loss of several valuable hours because of bad weather, the Japanese pilots did not expect to find so rich a harvest waiting for them. But they did not question their good fortune. The first flight of Japanese planes consisted of twenty-seven twin-engine bombers. They came over the unprotected field in a V-formation at a height estimated at 22,000 to 25,000 feet, dropping their bombs on the aircraft and buildings below, just as the air raid warning sounded. As at Pearl Harbor, the Japanese achieved complete tactical surprise.

            The first flight was followed immediately by a similar formation which remained over the field for fifteen minutes. The planes in this formation, as in the first, accomplished their mission almost entirely without molestation. American antiaircraft shells exploded from 2,000 to 4,000 feet short of the targets. After the second formation of bombers, came thirty-four Zeros which the Americans believed were carrier based to deliver the final blow with their low-level strafing attacks on the grounded B-17's, and on the P-40's with their full gasoline tanks. This attack lasted for more than an hour.

            With the first high wail of the siren, the men on the field below streamed from the mess halls. As the bombers passed over, the Americans could see the falling bombs glistening in the sunlight. Then came the explosions, hundreds of them, so violent that they seemed to pierce the eardrums and shake the ground. Throwing aside momentary disbelief and stupefaction, the men rushed to their battle stations. The scene was one of destruction and horror, unbelievable to the men who only a few minutes before had been eating lunch or servicing the planes. Flash fires sprang up and spread rapidly to the trees and long cogon grass around the field "roaring and crackling like an evil beast." Dense smoke and a heavy cloud of dust rose over the field.

            Against such odds, the Americans could offer little opposition. The 200th Coast Artillery (AA) experienced considerable difficulty with its 3-inch gun ammunition, the most recent of which was manufactured in 1932. The percentage of duds was abnormally high and "most of the fuses were badly corroded." Only one of every six shells fired, says one observer, actually exploded. Acts of personal heroism were commonplace. Ground and combat crews manned the guns of the grounded planes, and men dashed into flaming buildings to rescue their comrades as well as supplies and equipment. Others braved the strafing gunfire to aid the wounded. One private appropriated an abandoned truck and made seven trips with wounded men to the station hospital. During the attack, 3 P-40's of the 20th  Pursuit Squadron managed to get into the air, but 5 more were blasted by bombs as they taxied for the take-off.  A similar number was caught in the strafing attack. The 3 airborne fighters shot down 3 or 4 Japanese fighters.

            The 34th Pursuit Squadron, still at Del Carmen, could see the great clouds of smoke rising from Clark. The old P-35's of the squadron finally managed to take off and were soon in action against the superior Zeros over Clark. Though outclassed and outnumbered, the squadron knocked down three enemy fighters without loss to itself. But few of its planes were without serious damage. The 17th and 21st Pursuit Squadrons, on patrol over Bataan and Manila, made no effort to attack the Japanese aircraft, presumably because the communications center at Clark had been bombed out and news of the raid did not reach the Interceptor Command in time to dispatch aid.

            The 11th Air Fleet's attack against Clark was even more successful than the worried Japanese had expected. The operation had been well planned and executed. The first flights of bombers had concentrated on the hangars, barracks, and warehouses, and left them a burning ruin. Some of the grounded planes had been damaged in these bombings but the greatest casualties were inflicted by the low-level attacks of the Zeros which followed. Casualties in men were fifty-five killed and more than one hundred wounded.

            Simultaneously with the raid against Clark, other 11th Air Fleet planes were attacking the fighter base at Iba. The 12 planes of the 3d Pursuit Squadron, which had been patrolling over the China Sea, low on gas, returned to base. As they were circling to land, Iba was struck by 54 Japanese twin-motored naval bombers escorted by 50 Zeros. Effective action by the P-40's resulted in the loss of 2 Japanese fighters - (probables) and kept the Zeros from carrying out the low-level attacks which were so successful at Clark. But the losses at Iba ,were almost as great as at Clark. Barracks, warehouses, equipment, and the radar station were destroyed. Ground crews suffered heavy casualties and all but 2 of the 3d Squadron's P-40's were lost.

            The reaction from Washington head quarters of the Air Forces was delayed but explosive, despite a radio from MacArthur stating that the losses had been "due to overwhelming superiority of enemy forces."  General Arnold, when he received the news of the losses in the Philippines, "could not help thinking that there must have been some mistake made some where in my Air Force command," and he decided "to tell Brereton so."  Brereton had just returned from an inspection of Clark Field when he received a transoceanic telephone call from an irate General Arnold asking "how in the hell" an experienced airman like himself could have been caught with his planes down. Apparently he felt his explanation had not satisfied General Arnold, for he immediately reported the conversation to MacArthur and asked his help in presenting the situation to the Army Air Forces chief. According to Brereton, MacArthur was furious. "He told me to go back and fight the war and not to worry," Brereton recorded in his diary. "As I walked out of his office he asked Sutherland to get General Marshall on the phone."  Unfortunately, there is no record of the telephone conversation that followed.

            Thus, after one day of war, with its strength cut in half, the Far East Air Force had been eliminated as an effective fighting force. Of the modern combat aircraft, only 11 {error} of the original 35 B-17's remained. Fifty-three P-40's and 3 P-35's had been destroyed, and an additional 25 or 30 miscellaneous aircraft (B-10's, B-18's, and observation planes ) were gone. In addition, many of the planes listed as operational were heavily damaged. Installations at Clark and Iba were either burned out or badly hit. Total casualties for the day were. 80 killed and 150 wounded. The total cost to the Japanese was 1 fighters. The conclusion of the Joint Congressional Committee which investigated the Pearl Harbor attack, that it was the greatest military disaster in American history, is equally applicable to the Philippines.

 

Post-Mortem

            The catastrophe of Pearl Harbor over shadowed at the time and still obscures the extent of the ignominious defeat inflicted on American air forces in the Philippines on the same day. The Far East Air Force had been designed as a striking force to hit the enemy before he could reach Philippine shores. The heavy bombers were an offensive weapon, thought capable of striking the enemy's bases and cutting his lines of communication. Hopes for the active defense of the Islands rested on these aircraft. At the end of the first day of war, such hopes were dead.

            The tragedy of Clark Field, where the heavy bombers were caught like so many sitting ducks, becomes even more tragic when one considers the strange sequence of events that preceded it. Even before the war, the danger of basing the B-17's on Clark Field had been recognized. General MacArthur had written to General Marshall on 29 November, "The location of potential enemy fields and types of aircraft indicate that heavy bombers should be located south of Luzon where they would be reasonably safe from attack." He intended at the time to base the bombers in the Visayas. Time did not permit the construction of fields there, but before the out break of hostilities he did order General Brereton to move the heavy bombers from Clark Field to Mindanao.

            During the first week in December, Brereton had sent two squadrons of B-17's to the recently constructed field at Del Monte in Mindanao. The decision to move only two squadrons, Brereton states, was based on the expected arrival from the United States of the 7th Bombardment Group which was to be stationed at Del Monte. Had all the heavy bombers on Clark been transferred to Mindanao, there would have been no room for the 7th when it arrived.

            General Sutherland's version of the same incident differs considerably from that of the air force commander. It was at his insistence, he recollected, that even the two squadrons were sent south. "General Brereton," he says, "did not want them to go." Sutherland says he had ordered all the B-17's moved to Del Monte. On checking, he had found that only half of the planes had been sent and that General Mac Arthur's orders had not been obeyed.

            Wherever the responsibility lies for failing to move all the B-17's south, there still remains the question of why the remaining bombers were caught on the ground. Brereton argues that had he been permitted to attack Formosa when he wished, the planes would not have been on the field. Implicit is the assumption that if the raid had been successful, the Japanese could not have made their own attack. MacArthur denied knowledge of such a proposal in 1946, but in a radio sent on 8 December 1941 he stated that he intended to attack Formosa the next morning. General Sutherland, in one interview, claimed that Brereton was responsible for deferring the attack, and in another interview, that he himself deferred the attack because the Far East Air Force did not have sufficient target data for such an attack. It is clear that this project was discussed by Brereton and Sutherland, that MacArthur mentioned it in a radio that day, and that authorization to execute the attack was delayed until 1100 that morning.

            Whether such an attack would have had a serious chance of success is not argued by either Sutherland or Brereton. Knowing now what the Japanese had at Formosa, the possibility of a successful raid by the B-17's seems extremely remote. The Far East Air Force admittedly had sketchy information on the strength and disposition of the Japanese forces on Formosa. Had it been known that there were over five hundred Japanese planes waiting on Formosa, ready to take off, it is doubtful that anyone would have considered the project seriously. Moreover, the B-17's would have had to fly to Formosa, out of fighter range, unescorted. Once there, they would have been greeted by swarms of Zeros. "An attack on Formosa with its heavy air concentrations," MacArthur later wrote, "..... was impossible, would have had no chance of success." Sutherland's request for a photo reconnaissance mission prior to an attack would appear, therefore, to have been entirely justified. The heavy bombers were indeed far too valuable to risk in so hazardous a mission.

            Another unresolved question is why the warning of approaching Japanese aircraft did not reach the bomber commander at Clark Field in time to meet the attack. All forces in the Philippines had knowledge of the attack on Pearl Harbor hours before the first Japanese bombers appeared over Luzon. A dawn raid at Davao had given notice that the Japanese had no intention of bypassing the archipelago. The early morning bombings on Luzon gave even more pointed warning that an attack against the major airbase in the Islands could be expected. Colonel Campbell testifies that Clark Field had received word of the approaching Japanese aircraft before the attack. Colonel Eubank states that no such warning was ever received. Other officers speak of the breakdown of communications at this critical juncture. There is no way of resolving this conflicting testimony.

            Assuming that Colonel Eubank did not receive the warning from Nielson Field, there still remains one final question. Were the aircraft on the field adequately dispersed for wartime condition? It is not possible to state definitely how the aircraft were dispersed when they came in at 1130. There surely must have been some recognition of the danger of an enemy air attack at any moment. The Japanese state that they were "surprised to find the American aircraft lined up on the field."  And at least one flight of four B-17's was lined neatly on the field when the Japanese came over. Captain Ind tells of finding photographs, one of which was taken by an American pilot flying over the field, showing the planes inadequately dispersed for any but high-level bombing attacks. "This entire set of photographs," he says, "was removed from my desk a few nights later, No one seemed to know what had happened to them. " This question, like the others, remains unanswered.

            The full story of the events which preceded the Japanese air attacks against the Far East Air Force on the first day of the war will probably never be known. There was no time for reports, and if any records ever existed they have since been lost. The historian must rely on the memories of participants whose stories conflict at numerous points. General Arnold, eight years after the event, wrote that he was never able "to get the real story of what happened in the Philippines." Brereton's diary, in his opinion, did not provide "a complete and accurate account," and General Sutherland's story "does not completely clear it up, by any means.”

            Whatever the answers to the questions one may ask about the events of 8-9 December 1941 on Luzon, the significance of these events is clear. As at Pearl Harbor, the Japanese had removed in one stroke the greatest single obstacle to their advance southward. The Philippine garrison could expect little help in the near future. It was now almost entirely surrounded. The only path open lay to the south, and that, too, soon would be closed.

 

The Fleet Moves South

            The mission of the Asiatic Fleet in the event of war was to support the defense of the Philippines "as long as that defense continues." The actual employment of local naval defense forces was entrusted to the commander of the 16th Naval District, who was responsible for the joint tactical and strategical employment of his forces in co-operation with the Army. The commander of the Asiatic Fleet, at his discretion and when the situation demanded, was authorized to "shift base to British and Dutch ports."'

            The. force assigned for this task was pitifully small and deployed over a distance of more than 1,500 miles, from northern Luzon to Borneo. In the Manila Bay area were 5 destroyers, 2 of which were under repair and 3 on patrol; 21 submarines with their 3 tenders 3 of the underwater craft were being overhauled; 28 Catalinas (twin engine patrol bombers or PBY's); 4 utility planes; and 1 observation plane. The planes were organized into Patrol Wing 10 under Capt. F. D. Wagner, with one full squadron operating from Sangley Point, Cavite, and the remainder from Olongapo. In addition, there were 6 gunboats, a similar number of motor torpedo boats, 5 mine sweepers, and other auxiliary craft in the area. At Mariveles was the floating dry dock Dewey. The installations of the 16th Naval District, commanded by Rear Adm. Francis W. Rockwell, were centered in Manila and Sable Bays at Cavite, Corregidor, and Olongap with approximately 2,000 officers and men assigned. The reorganized and strengthened 4th Marines, with a strength of 1,600 and commanded by Col. Samuel L. Howard, was at Olongapo.

            The bulk of the surface strength of the Asiatic Fleet, organized into Task Force 5, was based south of Manila Bay. The flagship of the task force, the heavy cruiser Houston, was at Iloilo, in Panay. The light cruiser Boise, which belonged to the Pacific Fleet, was also in the Visayas, off Cebu, where she had gone after her arrival in Manila on 4 December with an Army convoy. At the Dutch Borneo port of Tarakan was the light cruiser Marblehead accompanied by 5 destroyers, and at Balikpapan were 4 more destroyers and a tender. The remaining 2 submarines of the Asiatic Fleet were on patrol off the Luzon coast, 1 in Lingayen Gulf and another in Sorsogon Bay. Patrolling to the south and linking up with the Dutch patrols from Borneo were 2 small aircraft detachments, 1 at Davao and another on a small island south of Palawan.

            On the morning of 8 December, the only portion of the Asiatic Fleet to come under fire was the small aircraft detachment at Davao with the tender Preston. After the attack from the Ryujo-based dive bombers and fighters, Preston let pass four Japanese destroyers, and then slipped out of Davao Gulf to escape southward.

            Before noon of the 8th, Rear Adm. William A. Glassford, commander of Task Force 5 and recently arrived from China, left by plane for Iloilo to hoist his flag aboard the Houston. He was joined there by the Boise from Cebu. That evening the aircraft tender Langley, protected by two destroyers, slipped out of Manila Bay under cover of darkness to join the cruisers at Panay. From there Glassford, on orders from Admiral Hart, led his small fleet south to Dutch Borneo to pick up oil and to assemble the rest of his force. He met no enemy ships on the way, only a long line of merchant vessels making good their escape. Thus, by the end of the first day of war, the striking force of the Asiatic Fleet, Task Force 5, was steaming south, and on 10 December had left Philippine waters.

 

The Japanese Gain Air and Naval Supremacy

            The Japanese followed up their successes of the first day of war with a series of air attacks aimed at destroying or driving American air and naval power from the Philippines. Before dawn of the 9th 7 Japanese naval bombers struck Nichols Field near Manila. The Japanese had planned a larger attack but the fog had again rolled in over Formosa during the early morning hours. The 7 bombers were enough to do the job. The loss of 2 or 3 P-40s, as well as other planes, and the destruction of ground installations completed the havoc begun at noon the previous day.

            On the 9th ground crews worked desperately to patch up the damaged planes, and units were reorganized. Antiaircraft defenses, especially in the Manila area, were strengthened, and one battery of the 60th Coast Artillery (AA) which had left Corregidor after dark on the 8th was in position on the morning of the 9th to furnish local protection for the port area, Nichols Field, and the oil storage and railroad yards. About five hundred men of the 200th Coast Artillery (AA) from Clark Field were dispatched to Manila during the day, supplied with equipment from the Philippine Ordnance Depot, and organized into a provisional antiaircraft regiment, later designated the 515th.

            The air attack against Formosa which General MacArthur had promised for the 9th never materialized. At 0800 one B-17 took off from Clark Field for a photo reconnaissance mission over Formosa but was forced back because of mechanical difficulty. Army fighters flew reconnaissance missions over northern Luzon and the PBY's of Patrol Wing 10 continued their patrols to the west and northwest. Numerous reports of enemy sightings were received but on investigation proved to be unfounded. Such reports, Hart noted, placed all Japanese vessels in one of two categories, "either a Transport or a Battleship!"  The Japanese also searched north Luzon during the day for evidence of American air activities.

            On the 9th, the thirteen heavy bombers on Mindanao moved forward to Luzon. Six of the Flying Fortresses landed at ill fated Clark Field at 1430; the rest reached San Marcelino, an emergency field along the west coast of Luzon, later in the after noon. The B-17's at Clark refueled and took off immediately after their arrival, remaining in the air until dark to avoid being caught on the ground as had the others the day before.

            The weather over Formosa on the morning of 10 December was threatening, but the Japanese, anticipating a change for the better, decided to press their advantage. Naval planes took off about 1000 to strike Luzon again. This time the target was the Manila Bay area. First warning of the approach of Japanese planes reached the Interceptor Command at Nielson Field at 1115, and fighters were immediately dispatched to cover Manila Bay, the port area, and Bataan. A half hour later, the enemy aircraft hit the Del Carmen Field near Clark, and the Nichols and Nielson Fields, near Manila. So severe was the attack against Nichols and so great the number of bombs dropped that the men at Nielson, nearly two miles away, thought the bombs were falling on their own field. The pattern set at Clark Field two days earlier was repeated. High-level bombers came in first and hit the barracks, offices, and warehouses. The fighters then came in at low level to strafe the grounded planes and installations. American planes returning to refuel were attacked by Zeros and destroyed. There was no antiaircraft fire and no fighter protection over the field; all the pursuits were engaged over Manila Bay.

            The naval base at Cavite received no less attention than Nichols Field. The Japanese force had divided north of Manila, and part had turned east toward the army installations. The rest, 54 bombers, had continued south toward Cavite on the south shore of Manila Bay. Half of these bombers attacked ships and small craft in the bay and the remainder went on toward the naval base. With maddening deliberation, the bombers flew over Cavite, dropping their bombs from a height of 20,000 feet, above the range of the 9 3-inch antiaircraft guns protecting the base. Almost every bomb fell within the navy yard. After the first run, the first flight withdrew and the other 21 bombers, having completed their attack against ships in the bay, flew in to strike the target.

            The attack lasted for two hours. As at Clark and Nichols, the opposition was feeble and the damage extensive. The entire yard was set ablaze; the power plant, dispensary, repair shops, warehouses, barracks, and radio station received direct hits. Greatest damage was done by the fire which spread rapidly and was soon out of control. Admiral Rockwell estimated that five hundred men were killed or seriously wounded that day. The large submarine Sealion received a direct hit, but Seadragon was pulled away in time by its tender. The most serious loss to the submarine force, however, was the destruction of well over two hundred torpedoes.

            Throughout the attack, Admiral Hart had watched the destruction of Cavite from atop the Marsman Building. That night, after receiving an account of the damage done, he reported to the Chief of Naval Operations in Washington that he regarded Manila untenable as a naval base since the enemy had control of the air, but promised to "continue submarine and air operations as long as possible." He then sent 2 destroyers, 3 gunboats, 2 submarine tenders, and 2 minesweepers south to join Task Force 5, "It is unfortunate," he noted in his report, "that two or three additional small ships were not sent south at this time."

            The naval vessels were not the only ships to move south. At the start of the war there had been about forty large merchant ships, many with valuable cargoes, in Manila Bay. The Navy had promptly closed the bay to all outbound traffic, and had extinguished the lighthouses on Corregidor and two other outlying islands. Fortunately the merchant vessels had escaped attack during the first day of operations.

            In the next two days, many commercial vessels sought protection in Manila Bay and were guided through the mine fields by the inshore patrol. During the attack of the 10th, the Japanese had dropped a few bombs among these ships, scoring one hit. Admiral Hart had told the shipmasters on the 11th that their vessels would be safer in Visayan ports, and that evening the commercial vessels began to steam out of Manila Bay. All but one finally escaped." The Japanese had missed a golden opportunity to cripple Allied shipping.

            On the morning of the 11th the fires at Cavite were burning more fiercely than ever. Evidently there was no chance of saving the yard. When Rockwell reported to Hart in Manila that day the two men agreed to salvage as much as possible from the ruins. Remaining supplies were to be distributed among the installations at Manila, Corregidor, and Mariveles. The base at Sangley Point was to be maintained as long as possible, and when no longer tenable the radio station and fuel supply were to be moved to Corregidor.

            Meanwhile, the Japanese air force continued the systematic destruction of the air and naval forces remaining in the Philippines. There had been no raids on the 11th, largely because the weather over Formosa had been bad. The planes returning from the raid on the 10th had been forced to set down wherever they could, thus scattering units among the many Formosan fields. The next day was spent in reassembling the units. On the 12th and 13th the Japanese again attacked in force. On these two days hundreds of Japanese Army and Navy planes struck targets on Luzon at will in a final effort to destroy the remnants of the Far East Air Force and the Asiatic Fleet.

            By this time American air power was at a low ebb. There were only 22 P-40's in commission, with 6 more promised if they could be repaired in time. In addition, between 5 and 8 P-35's and a handful of the obsolete P-26's were operational. Sixteen heavy bombers were still in commission but 5 of these were suitable only for low-altitude flights and another 4 were not fit for tactical missions. With the Far East Air Force thus reduced in strength it was decided to use the remaining planes for reconnaissance in order to conserve them as long as possible. The pursuit planes were based at Clark and Nichols, and the heavy bombers were withdrawn to Del Monte. On the morning of the 12th few American planes remained to hinder the Japanese.

            The enemy attack on the 12th came at noon, the hour when Clark and Cavite had been hit. Sixty-three naval bombers from Takao in Formosa arrived over Central Luzon between 1130 and 1200 and struck Iba and Clark Fields. Only a small number of planes flew over Clark; the remainder delivered the main attack against Iba, reporting the destruction of ten planes on the ground.

            That morning, the PBY's at Olongapo had been dispatched on a fruitless search for a nonexistent Japanese carrier reported off the Luzon coast. They were followed in by a Japanese force of Zeros which had been escorting a large number of bombers in a scheduled strike against one of the Manila fields. When the mission was canceled on account of poor weather over the target, the Zeros sought targets elsewhere. The returning PBY's offered an opportunity too good to be missed. Unseen by the Americans, the Japanese planes waited for the seven Navy patrol bombers to land, and then destroyed them at leisure. These same planes then went on to attack Batangas before returning to Formosa. MacArthur reported at the end of the day that "the crescendo of enemy air offensive was rapidly rising," with attacks by at least 113 planes. "Pilots have been ordered to avoid direct combat," he explained, in order to make a "show of strength and to have air reconnaissance."

            The next day [13th] almost 200 Japanese planes were over Luzon. The first attack came at dawn against Del Carmen. At 1030 and at 1100 Clark Field was attacked. About the same time Baguio and Tarlac were hit. These early strikes were made by Army planes. At 1230 the naval bombers put in an appearance. During the afternoon, Del Carmen, Clark, Nichols, Cabanatuan, and Batangas were hit at least once. The fields, already strewn with wrecked planes, received further damage. Over Sable Bay additional PBY's were destroyed, leaving less than a full squadron in Patrol Wing 10. By the end of the day, American Army and Navy air power in the Philippines had been virtually destroyed.

            One thing was clear to Admiral Hart by this time: the United States forces in the Philippines were on their own. With the loss of air power the possibility of effective naval support was extremely limited and the sea lanes along which reinforcements could be expected to travel were closed. He felt, therefore, that he must salvage what he could of the Asiatic Fleet for later operations in the defense of the Malay Barrier. On 14 December he sent out the remaining bombers of Patrol Wing 10, together with three tenders and such extra personnel and spare parts as could be carried south ward. Staff officers, including the chief of staff of the Asiatic Fleet, followed by plane and by boat. All that remained of the Asiatic Fleet in Philippine waters were 2 destroyers (1 under repair), 6 motor torpedo boats, 2 tenders, 3 gunboats, and various small craft, in addition to the 21 submarines. Admiral Hart himself decided to remain in Manila as long as the underwater craft could be operated and serviced from there.

            The position of the heavy bombers in Mindanao had by now become precarious. The Japanese were flying extensive reconnaissance missions in an effort to discover the remaining American aircraft. Thus far they had been unable to find the Del Monte field, but it was only a question of time before this last haven would be discovered and destroyed. Moreover, it was becoming increasingly difficult to service the B-17's with the inadequate facilities at Del Monte. There were no spare parts, engines, or propellers for the B-17's in the Philippines; B-18's and damaged B-17's had to be cannibalized to keep the bombers flying. The only tools were those in the possession of the crews. The men who worked on the planes all night often got no rest the next day because of air alerts. On some days the heavy bombers had to remain aloft during the daylight hours to avoid destruction on the ground. They dodged back and forth between Mindanao and Luzon, playing "a game of hide-and-seek that wore out men as well as planes."

            Under these conditions, it was evident that the remaining heavy bombers could not operate efficiently in the Philippines. General Brereton therefore requested authority on 15 December to move the B-17's to Darwin in northwest Australia, 1,500 miles away, where they could be based safely and serviced properly. His intention was to operate from fields near Darwin, using Clark and Del Monte as advance bases from which to strike enemy targets in the Philippines. Sutherland approved the plan the same day and secured General MacArthur's concurrence. The planes were immediately prepared for the long flight southward, and two days later the first group of B-17's left Del Monte airfield. By the following evening ten of the bombers had reached Batchelor Field outside Darwin. They had left Mindanao none too soon, for on the 19th the field at Del Monte received its first major air attack from Japanese planes based on the carrier Ryujo.

            By 15 December the air strength of the Philippines had been reduced to a handful of fighters. All hopes for preventing the main Japanese landings soon to come and for keeping the supply routes open rested now on these few planes and on the submarines of the Asiatic Fleet.
