The fall of Bataan on April 9, 1942, ended all organized opposition by the U.S. Army Forces Far East to the invading Japanese forces on Luzon, in the northern Philippines. The island bastion of Corregidor, with its network of tunnels and formidable array of defensive armaments, along with the fortifications across the entrance to Manila Bay, was the remaining obstacle to the 14th Japanese Imperial Army of Lieutenant General Masaharu Homma. Homma had to take Corregidor, since as long as the island remained in American hands, the Japanese would be denied the use of Manila Bay, the finest natural harbor in the Far East.
