Battle of Midway (1942)

The Battle of Midway (June 4-7, 1942) is considered the most decisive naval battle in history and the turning point of the Pacific War. The US Navy, having broken Japanese radio codes, ambushed and sank all four Japanese fleet carriers that had attacked Pearl Harbour, losing only the Yorktown. Japan never recovered its offensive capability. Without Midway, an East Asia under Japanese dominance would have been a plausible outcome of World War II.
