While the Battle of Midway is viewed as a turning point in the Pacific War, Japan remained on the offensive, as shown by its advances down the Solomon Islands. Only after the Allied victories in Guadalcanal and New Guinea (at Milne Bay and Buna–Gona) were these large-scale Japanese offensive actions stopped. Strategic initiative passed to the Allies, as it proved, permanently. The Guadalcanal campaign ended all Japanese expansion attempts and placed the Allies in a position of clear supremacy. The Allied victory at Guadalcanal was the first step in a long string of successes that eventually led to the surrender of Japan and the occupation of the Japanese home islands.
