"The Battle of Midway was the first decisive defeat suffered by the Japanese Navy in 350 years. Furthermore, it put an end to the long period of Japanese offensive action, and restored the balance of naval power in the Pacific. The threat to Hawaii and the west coast was automatically removed, and except for operations in the Aleutians area, where the Japanese had landed on the islands of Kiska and Attu, enemy operations were confined to the south Pacific. It was to this latter area, therefore, that we gave our greatest attention."
