Island Hopping across the Pacific Theater in World War II: The History of America’s Victorious Leapfrogging Strategy against Imperial Japan

The waters of the Pacific Ocean – stretching deep blue under the tropical sun, or scourged by typhoons – provided World War II's most far-flung battlefield. Two of the world's premier mid 20th century maritime powers, the United States of American and the Empire of Japan, grappled for supremacy across that vast expanse.

By the time the Battle of Midway was over in June 1942, the defeat was so devastating for Japan that it was actually kept secret from all but the highest echelons of the Japanese government. Along with the loss of hundreds of aircraft and over 3,000 men killed, the four Japanese aircraft carriers lost, when compared to America’s one lost carrier, was critical considering America’s huge shipbuilding superiority.

By the spring of 1943, American military planners had begun to create a plan to dislodge Japan from east and southeast Asia. To do so, parts of the Philippines were considered main strategic points in the potential Allied attack in the Pacific. The end goal of the Allied plan was an invasion of the Japanese home islands, in which heavy aerial bombardment would precede a ground assault. In order for this to occur, Allied forces would have to occupy areas surrounding Japan, with China adding to Luzon (the largest island in the Philippines) and Formosa (a large island off the coast of China) to create a triangle from which they could launch their bombers.

The Allied advance across the Pacific was based on this 1943 plan, with General MacArthur and his forces moving to the north through New Guinea, then Morotai Island, and then to Mindanao, which was the southernmost major island in the Philippines chain. At the same time, Admiral Chester Nimitz sent his fleet through the central Pacific, where they engaged Japanese forces at the Gilbert, Marshall, Marianas and Palau Islands en route to Mindanao.
