The first comprehensive account of the Filipino and American guerrilla resistance movement in Mindanao and Sulu during the Second World War. Utilizing heretofore untapped Philippine, American and Japanese primary sources, the book details heroism during the defense of Mindanao and Sulu during the Japanese invasion, the spontaneous development of anti-Japanese resistance groups including Christian, Muslim and indigenous Filipinos, the consolidation of these resistance groups into the Tenth Military District and the Sulu Area Command, and the key role these guerrillas played in the liberation of the area from Japanese rule. This is the first time a Filipino perspective is used to examine the largely unknown campaigns in the Philippine South. The historical book gives an account of how the people in the country’s southern region of Mindanao and the Sulu Archipelago, the Indigenous (Lumad), Islamized, and Christianized Filipinos, lived during more than three years (1941-1945) of Japanese invasion and occupation.
