why did the midway battle begin?

Answer 1

The Battle of Midway, fought near the Central Pacific island of Midway, is considered the decisive battle of the war in the Pacific. Before this battle the Japanese were on the offensive, capturing territory throughout Asia and the Pacific. By their attack, the Japanese had planned to capture Midway to use as an advance base, as well as to entrap and destroy the U.S. Pacific Fleet. Because of communication intelligence successes, the U.S. Pacific Fleet surprised the Japanese forces, sinking the four Japanese carriers, that had attacked Pearl Harbor only six months before, while only losing of one carrier. After Midway, the Americans and their Allies took the offensive in the Pacific.

Answer 2

The Japanese plan of attack, which included a secondary attack against the Aleutian Islands by a smaller fleet, was an attempt by the Japanese to lure America's few remaining carriers into a trap and sink them.[3] The Japanese also intended to occupy Midway Atoll to extend Japan's defensive perimeter farther from its home islands. This operation was considered preparatory for further attacks against Fiji and Samoa, as well as the invasion of Hawaii.

The Midway operation, like the attack on Pearl Harbor that had plunged the United States into war, was not part of a campaign for the conquest of the United States itself, but was aimed at its elimination as a strategic Pacific power, thereby giving Japan a free hand in establishing its Greater East Asia Co-Prosperity Sphere. It was also hoped that another defeat would force the U.S. to negotiate an end to the Pacific War with conditions favorable for Japan.[
