During the Second World War, the British realised they were unable to defend the colony from the powerful Imperial Japanese Navy. They destroyed the airfields, and especially the oil fields there and in Brunei before the Japanese landed on 16 December 1941. The small British forces surrendered. In 1943, the Chinese population of about 50,000 rebelled against Japan and seized some towns. They were overwhelmed with many executed. Australia sent special operation forces, which trained and armed local militia units and aided the landing of an Australian division in June 1945. Japanese forces numbered about 31,000, and held out until October 1945, long after the Emperor had surrendered.I.C.B Dear, ed, The Oxford Companion to World War II (1995) p 163
