The battle considered the turning point of the Pacific War during World War II is the Battle of Midway, fought in June 1942. This decisive naval battle resulted from Japan's attempted expansion in the Pacific, aiming to eliminate the U.S. as a naval power. However, American forces, having deciphered Japanese communications, set up an ambush. The U.S. decisively defeated the Japanese fleet, sinking four aircraft carriers while losing only one. The victory at Midway significantly shifted the balance of power in the Pacific, allowing the U.S. and its allies to take the offensive in subsequent operations.
