Further detail:
The Battle of Midway was a "midway" point in the battle against Japan in the Pacific. It allowed the United States, fighting for the Allies, to go from a defensive position to being on offense. The battle was one fought mainly with aircraft, and the US was able to knock four of Japan's aircraft carriers out of commission while only losing one of their own aircraft carriers.
