Island Hopping After the Battle of Midway, the United States launched a counter-offensive strike known as "island-hopping," establishing a line of overlapping island bases, as well as air control. The idea was to capture certain key islands, one after another, until Japan came within range of American bombers. Led by General Douglas MacArthur, Commander of the Allied forces in the Southwest Pacific, and Admiral Chester W. Nimitz, Commander-in-Chief of the Pacific Fleet, the first stage of the offensive began with the Navy under Nimitz, and Marine landings on Guadalcanal and nearby islands in the Solomons. From that point on, Nimitz and MacArthur engaged in "island-hopping" amphibious drives that bypassed strongly-held islands to strike at the enemy's weak points. In an effort to liberate the people of the Philippine Islands, MacArthur pushed along the New Guinea coast with Australian allies, while Nimitz crossed the central Pacific by way of the Gilberts, Marshalls, Marianas, Carolines, and Palaus. Both campaigns would entail seemingly endless, bloody battles — ultimately leading to the unconditional surrender of the Japanese.
