The Battle of Midway begins. During that morning, after sending planes to attack the U.S. base at Midway, the Japanese carriers Akagi, Kaga and Soryu are fatally damaged by dive bombers from USS Enterprise (CV 6) and USS Yorktown (CV 5). Later in the day, USS Yorktown is abandoned after bomb and torpedo hits by planes from Hiryu. The latter is, in turn, knocked out by U.S. carrier planes. Compelled by their losses to abandon their plans to capture Midway, the Japanese retire westward. The battle is a decisive win for the U.S, bringing an end to Japanese naval superiority in the Pacific.
