The defending forces outnumbered the Japanese invaders by 3 to 2, but were a mixed force of non-combat experienced regular, national guard, constabulary, and newly created Commonwealth units; the Japanese used their best first-line troops at the outset of the campaign. The Japanese 14th Army also concentrated its forces in the first month of the campaign, enabling it to swiftly overrun most of Luzon

The Southern Expeditionary Army was created on 6 November 1934, commanded by Gen. Count Hisaichi Terauchi, who had previously been Minister of War. It was ordered to prepare for war in the event that negotiations with the United States did not succeed in peacefully meeting Japanese objectives. Under Terauchi's command were four corps-equivalent armies, comprising ten divisions and three combined arms brigades, including the 14th Army. Operations against the Philippines and Malaya were to be conducted simultaneously when Imperial General Headquarters ordered.

The invasion of the Philippines had three objectives:
  • To prevent the use of the Philippines as an advance base of operations by American forces,
  • To acquire staging areas and supply bases to enhance operations against the Netherlands East Indies, and
  • To secure the lines of communication between occupied areas in the south and the Japanese Home Islands.

As of 30 November 1941, the strength of US Army Troops in the Philippines, including Philippine units, was 31,095, consisting of 2,504 officers and
28,591 enlisted (16,643 Americans and 11,957 Philippine Scouts).

Mobilization

MacArthur's mobilization plans called for induction of the ten reserve divisions between 1 September and 15 December 1941. The timetable was met on 1 September with the induction of one regiment per division, but slowed as a lack of facilities and equipment hampered training. The second regiments of the divisions were not called up until 1 November, and the third regiments were not organized until after hostilities began. Training was also seriously inhibited by language difficulties between the American cadres and the Filipino troops, and by the many differing dialects (estimated at 70) of the numerous ethnic groups comprising the army. By the outbreak of war, only two-thirds of the army had been mobilized, but additions to the force continued with the induction of the Constabulary and a portion of the regular army, until a force of approximately 120,000 men was reached.

The most crucial equipment shortfalls were in rifles and divisional light artillery. MacArthur requested 84,500 M1 Garand

s equipping the PA, of which there were adequate numbers, but the War Department denied the request because of production difficulties. The divisions had only 20% of their artillery requirements, and while plans had been approved to significantly reduce this gap, the arrangements came too late to be implemented before war isolated the Philippines.

By contrast, the Philippine Division was adequately manned, equipped, and trained. MacArthur received immediate approval to modernize it by reorganizing it as a mobile "triangular" division. Increasing the authorized size of the Philippine Scouts was not politically viable (because of resentments within the less-well-paid Philippine Army), so MacArthur's plan also provided for freeing up Philippine Scouts to round out other units.

Far East Air Force controversy

 was in progress at around 03:00 a.m. local time on 8 December 1941, FEAF interceptors had already conducted an air search for incoming aircraft reported shortly after midnight, but these had been Japanese scout planes reporting weather conditions.

Taiwan

 at Davao Bay. Authorization was withheld, but shortly afterward, in response to a telegram from General George C. Marshall instructing MacArthur to implement Rainbow 5, Brereton was ordered to have a strike in readiness for later approval.

Through a series of disputed discussions and decisions, authorization for the first raid was not approved until 10:15 a.m. local time for an attack just before sunset, with a followup raid at dawn the next day. In the meantime, Japanese plans to attack Clark and Iba Fields using land-based naval bombers and Zero fighters were delayed six hours by fog at its Formosa bases, so that only a small scale Army mission attacked targets in the northern tip of Luzon. At 08:00 a.m., Brereton received a telephone call from Gen. Henry H. Arnold

 warning him not to allow his aircraft to be attacked while still on the ground. FEAF launched three squadron-sized fighter patrols and all of its serviceable bombers on Luzon between 08:00 and 08:30 a.m. as a precautionary move. After MacArthur gave Brereton the authorization he sought at 10:15 a.m., the bombers were ordered to land and prepare for the afternoon raid on Formosa. All three pursuit squadrons began to run short on fuel and broke off their patrols at the same time.

The 20th Pursuit Squadron's Curtiss P-40B interceptors patrolled the area while the bombers landed at Clark Field

, also landed at Clark and had its aircraft refueled while its pilots ate lunch, then put its pilots on alert shortly after 11:00. All but two of the Clark Field B-17s were on the ground.

At 11:27 a.m. and 11:29 a.m., the radar post at Iba Field detected two incoming raids while the closest was still 130 miles out. It alerted FEAF headquarters and the command post at Clark Field, a warning that reached only the pursuit group commander, Major Orrin L. Grover, who apparently became confused by multiple and conflicting reports. The 3rd Pursuit Squadron took off from Iba at 11:45 with instructions to intercept the western force, which was thought to have Manila as its target, but dust problems during its takeoff resulted in the fragmentation of its flights. Two flights of the 21st PS at Nichols Field, six P-40Es, took off at 11:45, led by 1st Lt. William Dyess

. They started for Clark but were diverted to Manila Bay as a second line of defense if the 3rd PS failed to intercept its force. The 21st's third flight, taking off five minutes later, headed toward Clark, although engine problems with its brand-new P-40Es reduced its numbers by two. The 17th Pursuit Squadron took off at 12:15 p.m. from Clark, ordered to patrol Bataan and Manila Bay, while the 34th PS at Del Carmen never received its orders to protect Clark Field and did not launch. The 20th PS, dispersed at Clark, was ready to take off but did not receive orders from group headquarters. Instead a line chief saw the incoming formation of Japanese bombers and the section commander, 1st Lt. Joseph H. Moore, ordered the scramble himself.

Even though tracked by radar and with three U.S. pursuit squadrons in the air, when Japanese bombers of the 11th Kōkūkantai attacked Clark Field at 12:40 p.m., they achieved tactical surprise. Two squadrons of B-17s were dispersed on the ground. Most of the P-40s of the 20th PS were preparing to taxi and were struck by the first wave of 27 Japanese twin-engine "Nell"

 bombers) followed closely, then escorting Zero fighters strafed the field for 30 minutes, destroying 12 of the 17 American heavy bombers present and seriously damaging three others.

A near-simultaneous attack on the auxiliary field at Iba to the northwest by 54 "Betty" bombers was also successful: all but four of the 3rd Pursuit Squadron's P-40s, short on fuel and caught in their landing pattern, were destroyed in combat or from lack of fuel. Twelve P-40s from the 20th (four), 21st (two), and 3rd (six) Squadrons attacked the strafers but with little success, losing at least four of their own.

The Far East Air Force lost fully half its planes in the 45-minute attack, and was all but destroyed over the next few days, including a number of the surviving B-17s lost to takeoff crashes of other planes. The 24th Pursuit Group flew its last interception on December 10, losing 11 of the 40 or so P-40s it sent up, and the surviving P-35s of the 34th PS were destroyed on the ground at Del Carmen. That night FEAF combat strength had been reduced to 12 operable B-17s, 22 P-40s, and 8 P-35s. Clark Field was abandoned as a bomber field on December 11 after being used as a staging base for a handful of B-17 missions. Between December 17 and 20, the 14 surviving B-17s were withdrawn to Australia. Every other aircraft of the FEAF was destroyed or captured.

No formal investigation took place regarding this failure as occurred in the aftermath of Pearl Harbor. After the war, Brereton and Sutherland in effect blamed each other for FEAF being surprised on the ground, and MacArthur released a statement claiming that he had no knowledge of any recommendation to attack Formosa with B-17s. Walter D. Edmunds summarized the disaster as: "in the Philippines the personnel of our armed forces almost without exception failed to assess accurately the weight, speed, and efficiency of the Japanese Air Force." He quoted Maj. Gen. Emmitt O'Donnell, then a major in charge of the B-17s sent to Mindanao, as concluding that the first day was a "disorganized business" and that no one was "really at fault" because no one was "geared for war."

) feuding with Admiral Hart over lack of US Navy submarine action. MacArthur asked Admiral Hart: "What in the world is the matter with your submarines?" MacArthur complained that Hart's inactivity allowed Japan's navy freedom of action. According to Stimson, MacArthur felt that Hart's ships and submarines were ineffectual, but because Admiral Hart had lost his courage.

 area.

On 24 December, MacArthur invoked the pre-war war plan WPO-3 (War Plan Orange 3), which called for use of five delaying positions in central Luzon while forces withdrew into Bataan. This was carried out in part by the 26th Cavalry Regiment. He relieved Gen. Parker of his command of South Luzon Force and had him begin preparing defensive positions on Bataan, using units as they arrived; both the military headquarters and the Philippines government were moved there. Nine days of feverish movement of supplies into Bataan, primarily by barge from Manila, began in an attempt to feed an anticipated force of 43,000 troops for six months. (Ultimately 80,000 troops and 26,000 refugees flooded Bataan.) Nevertheless, substantial forces remained in other areas for several months.

 north of Manila. The South Luzon Force, despite its inexperience and equivocating orders to withdraw and hold, successfully executed "leapfrogging" retrograde techniques and crossed the bridges by 1 January. Japanese air commanders rejected appeals by the 48th Division to bomb the bridges to trap the retreating forces, which were subsequently demolished by Philippine Scout engineers on 1 January.

The Japanese realized the full extent of MacArthur's plan on 30 December and ordered the 48th Division to press forward and seal off Bataan. In a series of actions between 2 and 4 January, the 11th and 21st Divisions of the Philippine Army, the 26th Cavalry (PS) and the American M3 Stuart tanks of the Provisional Tank Group held open the road from San Fernando to Dinalupihan at the neck of the peninsula for the retreating forces of the South Luzon Force, then made good their own escape.

At the same time, in a critical mistake, they also relieved the 48th Division, responsible for much of the success of Japanese operations, with the much less-capable 65th Brigade, intended as a garrison force. The Japanese 5th Air group was withdrawn from operations on 5 January in preparation for movement with the 48th Division to the Netherlands East Indies.

 and contained in brutally dense jungle by ad hoc units made up of U.S. Army Air Corps troops, naval personnel, and Philippine Constabulary. The pocket was then slowly forced back to the cliffs, with high casualties on both sides. Landings to reinforce the surviving pocket on 26 January and 2 February were severely disrupted by air attacks from the few remaining FEAF P-40s, then trapped and eventually annihilated on 13 February.

A penetration in the I Corps line was stopped and broken up into several pockets. General Homma on 8 February ordered the suspension of offensive operations in order to reorganize his forces. This could not be carried out immediately, because the 16th Division remained engaged trying to extricate a pocketed battalion of its 20th Infantry. With further losses, the remnants of the battalion, 378 officers and men, were extricated on 15 February. On 22 February, the 14th Army line withdrew a few miles to the north and USAFFE forces re-occupied the abandoned positions. The result of the "Battle of the Points" and "Battle of the Pockets" was total destruction of all three battalions of the Japanese 20th Infantry and a clear USAFFE victory.

For several weeks, the Japanese, deterred by heavy losses and reduced to a single brigade, conducted siege operations while waiting refitting and reinforcement. Both armies engaged in patrols and limited local attacks. Because of the worsening Allied position in the Asia-Pacific region, U.S. President Franklin D.

, estimating that the offensive would require a month to end the campaign. The U.S. Philippine Division, no longer operating as a coordinated unit and exhausted by five days of nearly continuous combat, was unable to counterattack effectively against heavy Japanese assaults. On 8 April, the U.S. 57th Infantry Regiment (PS) and the 31st Division PA were overrun near the Alangan River. The U.S. 45th Infantry Regiment (PS), under orders to reach Mariveles and evacuate to Corregidor, finally surrendered on 10 April 1942. Only 300 men of the U.S. 31st Infantry successfully reached Corregidor.

Battle of Corregidor

Corregidor was a U.S. Army Coast Artillery position defending the entrance to Manila Bay. It was armed by both older seacoast disappearing gun batteries of the 59th and 91st Coast Artillery Regiments (the latter a Philippine Scouts unit), and an anti-aircraft unit, the 60th CA. The latter was posted on the higher elevations of Corregidor and was able to respond successfully to the Japanese air attacks, downing many fighters and bombers. The older stationary batteries with fixed mortars, and immense cannons, for defense from attack by sea, were easily put out of commission by Japanese bombers. The American soldiers and Filipino Scouts defended the small fortress until they had little left to wage a defense.

Early in 1942, the Japanese air command installed oxygen in its bombers to fly higher than the range of the Corregidor anti-aircraft batteries, and after that time, heavier bombardment began.

In December 1941, Philippines President Manuel L. Quezon, General MacArthur, other high-ranking military officers and diplomats and families escaped the bombardment of Manila and were housed in Corregidor's Malinta Tunnel
Malinta Tunnel
The Malinta Tunnel is a tunnel complex built by the United States Army Corps of Engineers on the island of Corregidor in the Philippines.

. Prior to their arrival, Malinta's laterals had served as high command headquarters, hospital and storage of food and arms. In March 1942, several U.S. Navy submarines arrived on the north side of Corregidor. The Navy brought in mail, orders, and weaponry. They took away with them the high American and Filipino government officers, gold and silver and other important records. Those who were unable to escape by submarine were eventually military POWs of Japan or placed in civilian concentration camps in Manila and other locations.

Corregidor was defended by 11,000 personnel, comprising the units mentioned above that were stationed on Corregidor, the U.S. 4th Marine Regiment

, and U.S. Navy personnel deployed as infantry. Some were able to get to Corregidor from the Bataan Peninsula when the Japanese overwhelmed the units there. The Japanese began their final assault on Corregidor with an artillery barrage on 1 May. On the night of 5–6 May, two battalions of the Japanese 61st Infantry Regiment landed at the northeast end of the island. Despite strong resistance, the Japanese established a beachhead that was soon reinforced by tanks and artillery. The defenders were quickly pushed back toward the stronghold of Malinta Hill.

Late on 6 May, Wainwright asked Homma for terms of surrender. Homma insisted that surrender include all Allied forces in the Philippines. Believing that the lives of all those on Corregidor would be endangered, Wainwright accepted. On 8 May, he sent a message to Sharp, ordering him to surrender the Visayan-Mindanao Force. Sharp complied, but many individuals carried on the fight as guerrillas.

Aftermath

The defeat was the beginning of three and a half years of harsh treatment for the Allied survivors, including atrocities like the Bataan Death March
Bataan Death March
The Bataan Death March was the forcible transfer, by the Imperial Japanese Army, of 75,000 American and Filipino prisoners of war after the three-month Battle of Bataan in the Philippines during World War II, which resulted in the deaths of thousands of prisoners.The march was characterized by...

 and the misery of Japanese prison camps, and the "Hell Ships" on which American and Allied men were sent to Japan to be used as labor in mines and factories. Thousands were crowded into the holds of Japanese ships, without water, food, or sufficient ventilation. The Japanese did not mark "POW" on the decks of these vessels, and some were attacked and sunk by Allied aircraft and submarines. For example on 7 September 1944 the Shinyo Maru

was sunk by the with losses of 668 POWs; only 82 POWs survived. Although the campaign was a victory to the Japanese, it was also a military setback as it took a longer time than anticipated to defeat the Filipinos and Americans. This required forces that would have been used to attack Borneo

Importance

Filipino-American resistance against the Japanese in the prepared defensive positions of Bataan and Corregidor lasted only three months, even though they outnumbered the invading forces. The valor of the Filipino and American soldiers is celebrated yearly on 9 April in the Philippines, Valor Day or Araw ng Kagitingan.
