Strategic Narrative Overview
The liberation began with amphibious landings on Leyte on 20 October 1944, triggering the massive Battle of Leyte Gulf. Allied forces advanced through Luzon, culminating in intense urban combat in Manila in early 1945 that devastated the city. Simultaneously, operations continued across the Visayas and Mindanao. The Mexican 201st Fighter Squadron and Australian naval and air units joined U.S. and Filipino ground forces throughout the campaign.
01 / The Origins
Imperial Japanese forces overran the Philippines in the first half of 1942, expelling American and Filipino forces and placing the archipelago under Japanese occupation. The Philippines held immense strategic value as a gateway to Japan's supply lines and the broader Pacific. After two years of occupation, Allied forces under General Douglas MacArthur planned a campaign to liberate the islands and restore the Philippine Commonwealth government.
03 / The Outcome
Japanese forces in the Philippines were ordered to surrender by Tokyo on 15 August 1945, following the atomic bombings of Hiroshima and Nagasaki and the Soviet entry into the Pacific War. Allied forces had not yet completed the liberation of all islands when the surrender order came. The campaign restored Philippine Commonwealth authority and paved the way for full Philippine independence, granted on 4 July 1946.
