At the Battle of the Java Sea, February 27, 1942, the Japanese Navy destroyed the main ABDA (American, British, Dutch, and Australian) naval force. The Netherlands East Indies campaign resulted in the surrender of Allied forces on Java. Meanwhile, Japanese aircraft had all but eliminated Allied air power in South-East Asia and began attacking Australia, with a major raid on Darwin, February 19. A raid by a powerful Japanese Navy aircraft carrier force into the Indian Ocean resulted in the Battle of Ceylon and sinking of the only British carrier in the theatre, HMS Hermes, as well as two cruisers and other ships, effectively driving the British fleet out of the Indian Ocean and paving the way for Japanese conquest of Burma and a drive towards India.
