Military history of the Philippines during World War II

The Commonwealth of the Philippines was attacked by the Empire of Japan on 8 December 1941, nine hours after the attack on Pearl Harbor (the Philippines is on the Asian side of the international date line). Although it was governed by a semi-independent commonwealth government, the United States of America controlled the Philippines at the time and possessed important military bases there. The combined Filipino-American army was defeated in the Battle of Bataan, which saw many war crimes committed and the Battle of Corregidor in April 1942, but guerrilla resistance against the Japanese continued throughout the war. Uncaptured Filipino army units, a communist insurgency, and supporting American agents all played a role in the resistance. Due to the huge number of islands, the Japanese never occupied many of the smaller and more minor islands. The Japanese control over the countryside and smaller towns were often tenuous at best.

In 1944, Allied forces liberated the islands from Japanese control in a naval invasion.

Far Eastern Command[edit]

On 25 July 1941, US Secretary of War Henry L. Stimson requested that US President Franklin D. Roosevelt issue orders calling the military forces of the Commonwealth into active service for the United States. Stimson explained, "All practical steps should be taken to increase the defensive strength of the Philippine Islands."


The following day President Roosevelt froze all Japanese assets within the United States and issued orders to absorb the forces of the Philippine Army. That same day the War Department created the US Army Forces in the Far East (USAFFE) command, with jurisdiction over the Philippine Department and the military forces of the Commonwealth. At the same time General Douglas MacArthur was recalled to active duty and designated the commander of the USAFFE.

Naval forces[edit]

At the outbreak of war the United States Navy's Asiatic Fleet was stationed at Cavite Naval Base in Manila Bay. Also stationed there was the Offshore Patrol.

Material and training inadequacies[edit]

The Philippine Army received clothing that was of poor quality. Their rubber shoes would wear out within 2 weeks. There were shortages of nearly every kind of equipment such as blankets, mosquito bars, shelter halves, entrenching tools, gas masks, and helmets.


During August, MacArthur had requested 84,500 M1 Garand rifles, 330 .30-caliber machine guns, 326 .50-caliber machine-guns, 450 37mm guns, 217 81 mm mortars, 288 75 mm guns, and over 8,000 vehicles. On 18 September, he was informed that, because of lend-lease commitments, he would not receive most of these items. As a result, the Philippine Army was forced to continue using the old Enfield and Springfield rifles.


The shipment of supplies depended upon the US Navy's limited cargo capacity. In September, the Navy announced its intentions to convert three transports into escort carriers, but this was not done after MacArthur observed that the loss of three transports would delay his reinforcements by more than two months.


The army then approved requests for 105 mm howitzers, 75 mm pack howitzers, 75 mm guns, .30-caliber machine guns, 37 mm guns, ten 250 ft station hospitals, one hundred and eighty sets of regimental infirmary equipment, jeeps, ambulances, trucks and sedans. By November, there were 1,100,000 tons of equipment, intended for the Philippines, piled up in US ports. Most of this never reached its destination. Meanwhile, the Navy did manage to transport 1,000,000 gallons of gasoline to the island. Much of this fuel would be stored on the Bataan Peninsula.


In 1941, many Filipino units went into battle without ever having fired their weapons. Many of the troops had also never even seen an artillery piece fired. The 31st Infantry Division (PA) signal officer was unable to establish radio communication with other units in the same camp. The commander of the Philippine 31st Infantry Division, Colonel Bluemel stated, "The enlisted men are proficient in only two things, one, when an officer appears, to yell 'attention' in a loud voice, jump up, and salute; two, to demand 3 meals per day."


Training and coordination were further complicated by language barriers. Enlisted Filipinos often spoke one language (such as Bikol or a Visayan language), their officers would speak another (such as Tagalog) and the Americans would speak English. There were some first sergeants and company clerks who could neither read nor write.
