USAFFE and American sponsored guerrillas disarming a Japanese sentry of his rifle during the raid at
Los Baños After Bataan and Corregidor, many who escaped the Japanese reorganized in the mountains as
guerrillas still loyal to the U.S. Army Forces Far East (
USAFFE). One example would be the unit of
Ramon Magsaysay in Zambales, which first served as a supply and intelligence unit. After the surrender in May 1942, Magsaysay and his unit formed a guerrilla force which grew to a 10,000-man force by the end of the war. Another was the
Hunters ROTC which operated in the Southern Luzon area, mainly near Manila. It was created upon dissolution of the
Philippine Military Academy in the beginning days of the war.
Cadet Terry Adivoso refused to simply go home as cadets were ordered to do, and began recruiting fighters willing to undertake guerrilla action against the Japanese. This force would later be instrumental, providing intelligence to the liberating forces led by General
Douglas MacArthur, and took an active role in numerous battles, such as the
Raid at Los Baños. When war broke out in the Philippines, some 300 Philippine Military Academy and ROTC cadets, unable to join the
USAFFE units because of their youth, banded together in a common desire to contribute to the war effort throughout the Bataan campaign. The Hunters originally conducted operations with another guerrilla group known as the
Marking Guerrillas, with whom they went about liquidating Japanese spies. Led by Miguel Ver, a PMA cadet, the Hunters raided the enemy-occupied Union College in Manila and seized 130
Enfield rifles. Also, before being proven false in 1985 by the United States Military, Philippine President
Ferdinand Marcos claimed that he had commanded a 9,000-strong guerrilla force known as the Maharlika Unit. Marcos also used
maharlika as his personal pseudonym; depicting himself as a bemedalled anti-Japanese Filipino guerrilla fighter during World War II. Marcos told exaggerated tales and exploits of himself fighting the Japanese in his self-published autobiography
Marcos of the Philippines which was proven to be fiction. His father,
Mariano Marcos, did however collaborate with the Japanese and was executed by Filipino guerrillas in April 1945 under the command of Colonel George Barnett, and Ferdinand himself was accused of being a collaborator as well. In July 1942,
South West Pacific Area (SWPA) became aware of the resistance movements forming in occupied Philippines through attempted radio communications to Allies outside of the Philippines; by late 1942, couriers had made it to
Australia confirming the existence of the resistance. By December 1942, SWPA sent Captain
Jesús A. Villamor to the Philippines to make contact with guerrilla organizations, eventually developing extensive intelligence networks including contacts within the Second Republic Government. A few months later SWPA sent Lieutenant Commander
Chick Parsons, who returned to the Philippines in early 1943, vetting guerrilla leaders and established communications and supply for them with SWPA. Through the
Allied Intelligence Bureau's Philippine Regional Section, SWPA sent operatives and equipment into the Philippines to supply and assist guerrilla organizations, often by
submarine. The large
cruiser submarines and , with a high capacity for personnel and supplies, proved especially useful in supporting the guerrillas. Beginning in mid-1943, the assistance to the guerrillas in the Philippines became more organized, with the formation of the
5217th Reconnaissance Battalion, which was largely composed of volunteer
Filipino Americans from the
1st and
2nd Filipino Infantry Regiments, which were established and organized in California. In
Nueva Ecija, guerrillas led by
Juan Pajota and
Eduardo Joson protected the U.S. Army Rangers and
Alamo Scouts who were conducting a
rescue mission of Allied POWs from a counterattack by Japanese reinforcements. Pajota and the Filipino guerrillas received
Bronze Stars for their role in the raid. Among the guerrilla units, the Blue Eagles were a specialized unit established for landmine and sniper detection, as well as in hunting Japanese spies who had blended in with the civilian population. Nonetheless, Japanese crackdowns on these guerrillas in Luzon were widespread and brutal. The Imperial Japanese Army, Kenpeitai and Filipino collaborators hunted down resistance fighters and anyone associated with them. One example happened to resistance leader
Wenceslao Vinzons, leader of the successful guerrilla movement in
Bicol. After being betrayed to the Japanese by a Japanese collaborator, Vinzons was tortured to give up information on his resistance movement. Vinzons however refused to cooperate, and he and his family, consisting of his father Gabino, his wife Liwayway, sister Milagros and children Aurora and Alexander, were bayoneted to death. , Filipino
Hukbalahap guerrilla leader
Hukbalahap resistance As originally constituted in March 1942, the Hukbalahap was to be part of a broad
united front resistance to the Japanese occupation of the Philippines. This original intent is reflected in its name:
"Hukbong Bayan Laban sa mga Hapon", which was "People's Army Against the Japanese" when translated into English. The adopted slogan was "Anti-Japanese Above All". The Huk Military Committee was at the apex of Huk structure and was charged to direct the guerrilla campaign and to lead the
revolution that would seize power after the war. One estimate alleges that the Huks killed 20,000 non-Japanese during the occupation.
Ethnic Chinese resistance Unique to other guerrillas in the Philippines were the
Wha-Chi; a resistance unit composed of
Filipino-Chinese and Chinese immigrants. They were established from the
Chinese General Labour Union of the Philippines and the Philippine branch of the Chinese Communist Party and reached a strength of 700 men. ==Resistance in Visayas==
