Lost in North Atlantic
When she was overdue in reaching home port, Muskeget was presumed lost in action with no survivors. At the time of her sinking, she had 121 men on board: 9 commissioned officers, 107 enlisted men, one Public Health Service officer, and four civilian employees of the U.S. Weather Service. German naval records recovered after the war indicated that U-755, under the command of Kapitänleutnant Walter Göing, reported torpedoing a U.S. auxiliary merchant cruiser in Muskeget's area of operation on 9 September 1942. It was probably this attack that caused the destruction of Muskeget and the loss of her entire crew. U-755 was herself sunk in the Mediterranean by a Royal Air Force Hudson on 28 May 1943.
