"During the closing days of 1944 King received the final promotion of his naval career. On 11 December the Congress passed a bill authorizing the appointment of four Fleet Admirals and four Generals of the Army. The President immediately named Leahy, King and Nimitz to the naval five-star rank (Halsey later became the fourth.), and Marshall, MacArthur, Eisenhower and Arnold to the corresponding grade in the Army. The Senate confirmed these appointments on 15 December 1944, and on 20 December- the third anniversary of his designation as Commander in Chief, United States Fleet- King took the oath of office as a Fleet Admiral in the United States Navy."
