William O. Darby had commanded the American Ranger Force during the battle. When the 179th Infantry Regiment of the 45th Infantry Division was nearly overrun on 18 February during the major German attempt to take out the beachhead, Darby was sent to take command and hold the ground. Darby later was assistant division commander of the 10th Mountain Division. He was killed in action on 30 April 1945, and was the only U.S. officer honored with a posthumous promotion to General during World War II.[citation needed]
