Plans Agreed Upon
On 1 September 1944 the Joint Chiefs of Staff in their 171st meeting reviewed the situation in the Pacific. The time had come when it was necessary to issue a directive for future operations in that area. After much discussion, the Joint Chiefs left in abeyance the question of what operation should follow Leyte but “directed the Joint Staff Planners to prepare, as a matter of urgency, a directive to the Commander in Chief, Southwest Pacific Area, and the Commander in Chief, Pacific Ocean Areas, to carry out the Leyte operation.”[29]
Accordingly, on 8 September, the two commanders were given the following missions: General MacArthur, after conducting the necessary preliminary operations, was to take the Leyte-Surigao area on 20 December, with Admiral Nimitz furnishing fleet support and additional assault shipping. Both commanders were to arrange for co-ordination of plans and mutual support of operations; to co-ordinate plans with General Joseph W. Stilwell, Commanding General, United States Army forces, China, Burma and India, in order to get maximum support from that theater; and to arrange with General Henry H. Arnold, Commanding General, Twentieth Air Force, for supporting operations.[30]
Concurrently with the issuance of this directive, momentous events were taking place in the Pacific. Admiral Halsey was in command of scheduled operations against the Palau Islands. On 7 and 8 September aircraft from his carriers struck at Yap and the Palau Islands, against which Admiral Nimitz had scheduled operations, and for the next two days bombed Mindanao. On the 12th and 14th the bombers hit the central Philippines in support of the operations against the Palau Islands and Morotai.
Admiral Halsey advised Admiral Nimitz that, as a result of the strikes, few serviceable planes in the Philippines were left to the Japanese, the bulk of the enemy’s oil supplies was destroyed, there was “no shipping left to sink,” the “enemy’s non-aggressive attitude [was] unbelievable and fantastic,” and “the area is wide open.”[31] Halsey also told Nimitz that one of his downed carrier pilots had been told by his Filipino rescuers that there were no Japanese on Leyte.[32] He therefore felt that it was time to accelerate the operations in the Pacific, and he strongly recommended that the intermediate operations—Yap, Talaud, and the Sarangani Bay area on Mindanao—be canceled. Leyte could be seized immediately and cheaply without any intermediate operations. Halsey’s fleet could cover the initial landing until land-based aircraft could be established. The force intended for the occupation of Yap could be made available to General MacArthur.[33]
When this message was received, the Combined Chiefs of Staff were attending a conference in Quebec. The recommendations were transmitted to Quebec by Admiral Nimitz, who offered to place at MacArthur’s disposal the III Amphibious Force, including the XXIV Corps, which was loading at Pearl Harbor for Yap. General Marshall so informed General MacArthur and asked his opinion on the proposed change of target date.[34]
The message reached MacArthur’s headquarters at Hollandia, on New Guinea, while MacArthur was en route to Morotai and observing radio silence. His chief of staff advised General Marshall that although the information from the rescued pilot that there were no Japanese on Leyte was incorrect, the intermediate operations could be eliminated. The 1st Cavalry Division and the 24th Infantry Division with sufficient service troops were available for the Leyte operation; adequate air strength could be provided; the logistic support was practicable; and the XXIV Corps could be used.[35]
General Marshall received this answer at Quebec on 15 September while he, Admiral Leahy, Admiral King, and General Arnold were at a formal dinner given by Canadian officers. The Americans withdrew from the table for a conference. Within an hour and a half after the message arrived, the Joint Chiefs ordered MacArthur and Nimitz to cancel the three intermediate operations of Yap, Talaud, and Sarangani, co-ordinate their plans, and invade Leyte on 20 October.[36]
Later that evening, as he was on his way to his quarters after the dinner, General Marshall received this message: “Subject to completion of arrangements with Nimitz, we shall execute Leyte operation on 20 October.... MacArthur.”[37]
On 3 October the Joint Chiefs of Staff directed General MacArthur to occupy Luzon on 20 December 1944, the date originally set for the entrance into Leyte.[38] The decision had been made. General MacArthur was to return to the Philippine Islands in force.
