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.
