After Pearl Harbour was struck, the Japanese swept across the Pacific. Thousands of Americans and Filipinos died on the Bataan Death March and prisoners were forced to labour for the Japanese, building the infamous Thai-Burma 'death' railway. But the Allies struck back. 'Doolittle's Raiders' flew from an aircraft carrier to bomb Tokyo itself. The Battle of Midway halted Japanese naval expansion, while U.S. Marines on Guadalcanal learned to take no prisoners. Australian forces defending their homeland against invasion turned back the Japanese in New Guinea - a brutal fight against desperate troops, some of whom turned to cannibalism.
