Inlet of the South China Sea extending into southwestern Luzon island, Philippines.
Considered one of the world's great harbours, it forms a nearly landlocked body of water with an area of 770 sq mi (2,000 sq km). It measures 36 mi (58 km) across at its widest point. The decisive Battle of Manila Bay , in the Spanish-American War , took place there in 1898. The Japanese gained control of the bay in 1942 during World War II, but it was recaptured by U.S. forces in 1945. Corregidor Island, the scene of intense fighting in the war, divides the bay's entrance into the South Channel and the North Channel.
