NIMITZ TO HEAD PACIFIC OPERATIONS
Washington, D.C. · April 3, 1945
On this date in 1945 the Roosevelt administration appointed Gen. Douglas MacArthur Commander-in-Chief U.S. Army Forces Pacific (AFPAC), responsible for all Army and Army Air Forces units in the Pacific theater excepting Maj. Gen. Curtis LeMay’s Twentieth Air Force based in the Marianas. At the same time Adm. Chester W. Nimitz became Commander-in-Chief, United States Pacific Fleet (CinCPac). These moves were part of the preparations for Operation Downfall, the invasion of Japan set to begin in October 1945. MacArthur, who was recalled to active duty in June 1941 to mobilize the Philippine Army, was appointed Supreme Commander of the Southwest Pacific Area (SWPA) upon its creation in April 1942. (SWPA was one of three areas in the Pacific Theater; the other two were Pacific Ocean Areas (POA) and the Southeast Pacific Area.) From that post MacArthur moved on to head the Allied occupation of Japan (1945–1951). Ten days after the attack on Pearl Harbor, Nimitz was appointed Commander-in-Chief, United States Pacific Fleet (CINCPACFLT). In March 1942 Nimitz was elevated to Commander-in-Chief, Pacific Ocean Area (CinCPOA), which placed all U.S. and Allied air, land, and sea forces under him. On December 15, 1944, President Franklin D. Roosevelt appointed Nimitz to the rank of Fleet Admiral of the United States Navy, a five-star rank only established the previous day by an Act of the U.S. Congress. In the last fourteen months of the war, Nimitz’s Fleet Forces inflicted a decisive defeat on the Japanese in the Battle of the Philippine Sea (June 19–20, 1944); captured Saipan (June 15–July 9, 1944), Guam (July 21–August 10, 1944), and Tinian (July 24–August 1, 1944); and secured in rapid succession Peleliu (September 15–November 27, 1944), Angaur (September 17–October 22, 1944), and Ulithi (September 1944), which became the undisclosed Pacific base for the major operations late in the war. In the Philippines his ships scored an historic victory in the Battle of Leyte Gulf (October 24–26, 1944). Nimitz culminated his Pacific strategy by successful amphibious assaults on Iwo Jima (February 19–March 26, 1945) and Okinawa (April 1–June 22, 1945). On September 2, 1945, on board the USS Missouri in Tokyo Bay, Nimitz signed for the United States when Japan formally surrendered in a twenty-three-minute ceremony that was broadcast around the world.
