Overview
Behind the decision to go into Leyte lay a series of strategically significant victories, which had followed a staggering initial reverse. American prewar plans for the Pacific had originally been based on the assumption that only the United States and Japan would be at war and that the U.S. Pacific Fleet would be in existence. But the destruction of the fleet at Pearl Harbor and the entrance of Germany and Italy into the war nullified these plans. The strategy of the Joint Chiefs of Staff in early 1942, therefore, was concerned chiefly with trying to limit the rapid advance of the Japanese and with keeping the line of communications to Australia open. The Pacific Theater was divided into command areas—the Southwest Pacific Area, with General Douglas MacArthur as Supreme Commander (he referred to himself, however, as Commander in Chief), and the Pacific Ocean Area (which included the Central Pacific), with Admiral Chester W. Nimitz as Commander in Chief. In 1942 and 1943 the Allied forces had halted the Japanese at Papua and Guadalcanal and started to push them back. On 8 May 1943 the Joint Chiefs approved a “Strategic Plan for the Defeat of Japan,” which was endorsed by the Combined Chiefs in December. The objective of the plan was to secure the unconditional surrender of Japan, an objective that might necessitate an invasion of the Japanese home islands. As such an invasion promised to be a “vast undertaking,” it would be necessary to secure a large supply base from which a great aerial offensive could be mounted against Japan. According to the original plan this base was to be located in China, but the Mariana Islands were afterward substituted for China. The plan called for the acquisition of successive island bases which could be used as “steppingstones,” preferably those which would shorten the sea route, provide for its security, and at the same time deny to the Japanese bases from which they might interfere with the Allied line of communications. The main effort was to be through the waters of the Pacific Ocean. Nimitz’ operations were to be conducted west through the Japanese mandated islands while MacArthur’s proceeded northwest along the New Guinea coast. The two series of operations were to be mutually supporting. Although no specific islands were named in the Strategic Plan, the Philippine Archipelago, because of its strategic position and long possession by the United States, naturally loomed large in the planning. The Philippines lie athwart all sea routes south from Japan to the economically important Netherlands Indies—rich in rubber, tin, oil, and rice. The capture of the Philippines would help to sever this line of communications and would furnish an excellent staging area for attacks against China, Formosa, or Japan. Aside from strategic considerations, the liberation of the Islands was important for reasons of Far Eastern politics and prestige. The obligation of the United States to the subjugated Filipino people could not be lightly ignored. Furthermore, General MacArthur was imbued with a burning determination to return to the Philippine Islands and avenge the humiliating defeats suffered by the American forces in 1941 and 1942. By the spring of 1944 the operations in the Pacific were going so well that the successes had exceeded even the most optimistic hopes of any of the planning officers. On 12 March the Joint Chiefs ordered General MacArthur to prepare plans for a return to Mindanao, southernmost island of the Philippines, with a target date of 15 November 1944. General MacArthur on 15 June issued a plan for his future operations. The entrance into the Philippines was to be accomplished in two phases. The first would be a preliminary operation on 25 October into the Sarangani Bay area in southern Mindanao in order to establish land-based air forces to augment the carrier-based air support for the principal effort.
