Admiral Chester Nimitz, the commander of American naval forces in the Pacific, moved to defend the island. On Junes 3, 1942, his scout planes found the Japanese fleet. The Americans sent torpedo planes and dive bombers to the attack. The Japanese were caught with their planes still on the decks of their carriers. The results were devastating. by the end of the Battle of Midway, the Japanese had lost four aircraft carriers, a cruiser, and 250 planes.
