"The Congress during World War II created a limited number of five-star ranks for the Army and the Navy, designated General of the Army and Fleet Admiral. The Navy by law was authorized four Fleet Admirals. Three were easily chosen: Ernest J. King, Chester W. Nimitz, and William S. Leahy, chief of staff to President Roosevelt. The choice for the fourth was between Halsey and Spruance. Secretary of the Navy Forrestal told King that he would have to decide between the two. It was a difficult task, because Halsey and Spruance both had influential supporters in Washington. The most powerful was Representative Carl Vinson, Chairman of the House Armed Services Committee, who had publicly endorsed Halsey. The Navy did not like to oppose Vinson on anything. King put off the decision for several months, then sent a memorandum to Forrestal summarizing the pros and cons of each candidate. There were many things in Halsey's favor. He was the senior admiral, he had been at sea since 1938, his performance in the South Pacific in the dark days of 1942-1943 had been brilliant, and his raids against the Japanese empire in late 1944 had been spectacular and devastating. Against him, wrote King, were his errors in judgment in not evading two typhoons that severely damaged his fleet in the latter part of the war. King said very little about Halsey's questionable decisions at the Battle of Leyte Gulf. King then turned to Spruance, whom he would have endorsed for CNO had it not been for Spruance's mandatory retirement age. "As to brains," wrote King, "the best man in every way." His record in the Pacific was self-evident. The only argument against Spruance was that he had held relatively subordinate commands during the early part of the war."
