Philippine Commonwealth Army. It was the official ground force of the Commonwealth of the Philippines, established following the passage of the National Defense Act of 1935. Created under the military advisorship of Douglas MacArthur, its primary mission was to provide for the national defense in preparation for full independence from the United States. The army played a central and tragic role during the World War II in the Pacific War, fighting valiantly in the initial defense, enduring the brutal Japanese occupation of the Philippines, and participating in the liberation campaign.

History

The army's origins are rooted in the Tydings–McDuffie Act, which established the Commonwealth of the Philippines and mandated the creation of a national defense force. President Manuel L. Quezon appointed Douglas MacArthur as a Military Advisor to the Commonwealth Government of the Philippines to oversee its development. The foundational legislation, the National Defense Act of 1935, called for a small regular force, a large reserve component, and the training of citizens through a system akin to the Reserve Officers' Training Corps. Mobilization accelerated dramatically following the attack on Pearl Harbor and the subsequent invasion of the Philippines by the Imperial Japanese Army.

Organization and structure

Modeled after the United States Army, it was organized into divisions, regiments, and battalions. The core was the Philippine Division, a regular unit of the United States Army Forces in the Far East that included both American and Filipino personnel. Ten reserve divisions were mobilized from various regions, such as the 11th Division from the Visayas and the 91st Division from the Bicol Region. Command and control was integrated with American forces under the United States Army Forces in the Far East, with key leadership from generals like Jonathan M. Wainwright and George C. Marshall.

Equipment and uniforms

Initially equipped with outdated World War I-era matériel, including the M1917 Enfield rifle and the Stokes mortar, the force suffered from chronic shortages. Uniforms were based on American patterns, typically consisting of khaki shirts and trousers with the distinctive M1917 helmet. Later, some units received more modern equipment like the M1 Garand rifle as part of pre-war reinforcement efforts. During the Japanese occupation of the Philippines, guerrilla units wore improvised clothing and used captured Japanese Arisaka rifles or privately-owned weapons.

Campaigns and battles

Its first major test was the Philippines campaign (1941–1942), where it fought in critical defensive actions such as the Battle of Bataan and the Battle of Corregidor. Following the surrender of Allied forces, many soldiers endured the Bataan Death March or joined guerrilla movements like those led by Wendell Fertig on Mindanao and Macario Peralta in the Visayas. The army was reconstituted to fight under the Sixth United States Army and Eighth United States Army during the Philippines campaign (1944–1945), participating in major landings at Leyte and Lingayen Gulf and the brutal urban combat of the Battle of Manila.

Integration into the Armed Forces of the Philippines

Upon the granting of full independence on July 4, 1946, the army was formally dissolved and its personnel, units, and traditions were integrated into the newly established Armed Forces of the Philippines. The Philippine Army became the direct successor service. This transition was formalized under the administration of President Manuel Roxas, with the Republic Act No. 34 providing the legal framework for the new military establishment, inheriting the veterans and institutional lessons from the Commonwealth era.

Legacy and memorials

The army is remembered for its sacrifice and resilience during a pivotal period in Philippine history. Its veterans are honored at sites like the Capas National Shrine in Tarlac, which commemorates the victims of the Bataan Death March, and the Libingan ng mga Bayani in Taguig. The annual Araw ng Kagitingan (Day of Valor) on April 9th marks the fall of Bataan. The collective experience of its soldiers is documented in institutions such as the Philippine Veterans Affairs Office and memorialized in the Bataan World War II Museum.
