During the remainder of World War II, she served the Royal Navy as HMS Patroller and operated in the Atlantic on convoy escort and patrol duty, with brief stints as a transport carrier for both the Army and Navy. Arriving Norfolk, Virginia, 9 December 1946, she was returned to the United States Navy the same day. Her name was struck from the Naval Vessel Registry 7 February 1947 and she was sold to Waterman Steamship Corp., 26 August 1947 as Almkerk (later renamed Pacific Reliance). She was scrapped in Taiwan in 1974.
