Philippine Army, Guerrilla Forces under USAFFE

• Origins in World War II: The Philippine Army Guerrilla Forces under USAFFE (United States Army Forces in the Far East) were formed after the Japanese invasion of the Philippines in December 1941, when many Filipino and American soldiers avoided capture and took to the hills to continue the fight. • General Douglas MacArthur's Role: General MacArthur, commander of USAFFE, encouraged the organization of guerrilla resistance to support future Allied operations and provide intelligence on Japanese movements. • Widespread Operations: The guerrilla forces operated all over the Philippines, including Luzon, Visayas, and Mindanao, carrying out sabotage, ambushes, and collecting vital intelligence. • Code Names and Secret Networks: Many guerrilla units used code names and established clandestine radio networks to communicate with Allied command in Australia and later with returning American forces. • Major Leaders: Notable guerrilla leaders included Lt. Col. Wendell Fertig in Mindanao and Col. Russell Volckmann in Northern Luzon, both American officers who escaped capture. • Support from Civilians: The guerrilla movement relied heavily on civilian support for supplies, information, and shelter, making it a true people's war against the Japanese occupation. • Recognition After the War: After the liberation of the Philippines, over 260,000 Filipinos who served in recognized guerrilla units were incorporated into the Philippine Army and recognized as veterans by the U.S. and Philippine governments. • Liberation Assistance: Guerrilla forces played a critical role in assisting the Allied landings in 1944-1945, guiding troops, providing intelligence, and participating in direct combat operations. • Sabotage and Resistance: Guerrilla units sabotaged Japanese supply lines, destroyed bridges, and rescued prisoners of war, significantly hampering Japanese operations. • Famous Operations: One of the most famous guerrilla actions was the raid on the Cabanatuan POW camp in January 1945, where Filipino guerrillas and U.S. Army Rangers freed over 500 Allied prisoners in a daring rescue operation.
