"And [the attack on Pearl Harbor] was merely the opening salvo. Thereafter, Japanese forces fanned out across the Pacific and South-East Asia in a vast centrifugal offensive that achieved breathtaking speed and success. On December 8, the first Japanese troops landed on the eastern side of the Malay peninsula, followed two days later by the rest of General Yamashita Tomoyuki's 25th Army. Naval aircraft based in Saigon smashed the British naval force off Malaya, sinking the battleships Prince of Wales and Repulse. Lieutenant-General Iida Shôjirô's 15th Army stormed up the Kra isthmus into the heart of Burma, routing better-armed but less mobile British forces. British Borneo was invaded on December 16; a month and three days later it surrendered. Hong Kong's garrison of 12,000 held out for barely a week after Japanese troops landed there on December 18; it surrendered on Christmas Day. Meanwhile the 25th Army was advancing down the Malayan peninsula towards Singapore, using bicycles to speed down the well-tended plantation roads. On February 15 Lieutenant-General Arthur E. Percival and his garrison of 16,000 Britons, 14,000 Australians and 32,000 Indians surrendered, unaware of the exhausted condition of their 30,000 adversaries, who had all but run out of food and ammunition. Here was a humiliation even worse than that of May 1940, and there was more to come. Rangoon fell in March, despite Chinese attempts to assist Burma's beleaguered British-Indian defenders; Mandalay followed on May 1, along with the Andaman Islands in the Bay of Bengal. As General Henry Pownall admitted, the British had been 'out-generalled, outwitted and outfought . . . by better soldiers'."
