On February 26, an ammunition dump on the Philippine island of Corregidor is blown up by a remnant of the Japanese garrison, causing more American casualties on the eve of U.S. victory there.
In May 1942, Corregidor, a small rock island at the mouth of Manila Bay, remained one of the last Allied strongholds in the Philippines after the Japanese victory at Bataan. Constant artillery shelling and aerial bombardment attacks ate away at the American and Filipino defenders.
Although still managing to sink many Japanese barges as they approached the northern shores of the island, the Allied troops could not hold the invader off any longer. Gen. Jonathan Wainwright, commander of the U.S. armed forces in the Philippines, offered to surrender Corregidor to Japanese Gen. Masaharu Homma, but Homma wanted the complete, unconditional capitulation of all American forces throughout the Philippines. Wainwright had little choice given the odds against him and the poor physical condition of his troops—he had already lost 800 men. He surrendered at midnight. All 11,500 surviving Allied troops were evacuated to a prison stockade in Manila.
But the Americans returned to the Philippines in full strength in October 1944, beginning with the recapture of Leyte, the Philippines’ central island. It took 67 days to subdue, with the loss of more than 55,000 Japanese soldiers during the two months of battle, and approximately another 25,000 mopping up pockets of resistance in early 1945. The U.S. forces lost about 3,500.
Following the American victory of Leyte was the return of Gen. Douglas MacArthur and the struggle for Luzon and the race for Manila, the Philippine capital. One week into the Allied battle for Luzon, U.S. airborne troops parachuted onto Corregidor to take out the Japanese garrison there, which was believed to be 1,000 strong, but was actually closer to 5,000. Fierce fighting resulted in the deaths of most of the Japanese soldiers, with the survivors left huddling in the Malinta Tunnel for safety.
Ironically, the tunnel, 1,400 feet long and dug deep in the heart of Corregidor, had served as MacArthur’s headquarters and a U.S. supply depot before the American defeat there. MacArthur feared the Japanese soldiers could sit there for months. The garrison had no such intention, though, and ignited a nearby ammunition dump—an act of defiance, and possibly of mass suicide.
Most of the Japanese were killed in the explosion, along with 52 Americans. Those Japanese who survived the blast were forced out into the open and decimated by the Americans. Corregidor was officially in American hands by early March.
