Formation of Underground Resistance
Filipino soldiers who escaped from Bataan and other POW camps went into the mountains of Luzon or relied on Filipino locals to guide them to other safe zones harboring guerrilla fighters or Allied stragglers after the Allies surrender. There was no main defense of the Manila Bay, and radio and communications also stopped as the Japanese military continued their invasion. Ramon Magsaysay Sr., a Filipino soldier who escaped after the fall of Corregidor was the major face of the Western Luzon Guerrilla Force who commanded over 10,000 guerrillas and would later become the 7th president of the Republic of the Philippines. Most soldiers joined guerrilla units or went into hiding with the help of Filipino civilians. Many of the soldiers made desperate attempts to establish communications with the Allied force.
