She was completed at the end of the war and supplied Allied troops in Europe with food and horses, and, on return trips to the United States, brought troops back home. After three round transatlantic trips in supporting the troops, she was returned to the U.S. Shipping Board, which eventually sold her in 1937. She then became the British freighter Federlock which was captured in 1940 by the Japanese, who renamed the ship the Hakusan Maru. The ship sailed carrying Japanese cargo until sunk by an American submarine in 1945.
