The Battle of Leyte in the Pacific campaign of World War II was the amphibious invasion of the island of Leyte in the Philippines by American forces and Filipino guerrillas under the overall command of General Douglas MacArthur. The combined forces fought against the Imperial Japanese Army in the Philippines led by General Tomoyuki Yamashita. The operation, codenamed King Two, launched the Philippines campaign of 1944–45 for the recapture and liberation of the entire Philippine Archipelago and to end almost three years of Japanese occupation.
