Few batties have been so decisive or decided so swiftly. In only four minutes the elite of Japan's naval airpower was devastated by a surprise US divebomber attack. Japan's legendary naval commander-in-chief, Isoroku Yamamoto, had hoped to settle the future ot the war in the Pacific in one decisive operation. His over-complex plan did - but not in the way he had intended; for the briIliance of US Naval codebreakers, the courage of its naval pilots, and the daring of Chester Nimitz brought the apparenty unstoppable Japanese offensive of the previous six months to a sudden halt. Four-colour graphics and action footage explain the battle at which the tide turned inexorably in favour of the United States.
