The outbreak of war in the Pacific in December 1941 found the British in Malaya completely unprepared. During the 1930s, anticipating the rising threat of Japanese naval power, they had built a great naval base at Singapore, but never anticipated an invasion of Malaya from the north. Because of the demands of the war in Europe, there was virtually no British air capacity in the Far East. The Japanese were thus able to attack from their bases in French Indo-China with impunity, and despite stubborn resistance from British, Australian, and Indian forces, they overran Malaya in two months. Singapore, with no landward defences, no air cover, and no water supply, was forced to surrender in February 1942. British North Borneo and Brunei were also occupied.
