LEYTE: THE RETURN TO THE PHILIPPINES

CHAPTER I

The Strategic Plan

“It is with the deepest regret that I must inform you that conditions over which I have no control have necessitated the surrender of troops under my command.”[1] With this message of 20 May 1942, from Lt. Col. Theodore M. Cornell, U.S. Army, to Bernardo Torres, Governor of Leyte, the control which the United States had held over the island since 1898 came to an end. Nearly two and a half years were to elapse before the sound of naval guns in Leyte Gulf would announce to the world the opening of the Leyte Campaign, the first phase of the re-entry of American forces into the Philippine Archipelago. (Map 1—inside back cover)

The primary purpose of the Leyte Campaign was to establish an air and logistical base in the Leyte area in order to support operations in the Luzon-Formosa-China coast area and particularly to nullify Japanese strength in Luzon. Leyte is one of the Visayan Islands, which constitute the geographical heart of the Philippines. It was hoped that the fertile Leyte Valley, broad and flat, could be utilized for major airfields and base sites from which large-scale operations could be launched against the rest of the Philippines.

Preliminary Discussion

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.[2] 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[3] 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.[4]

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.[5]
