"Paul Jacobi" spent most of 1943 inactive in the Arctic before returning to Germany in September for another refit. She was badly damaged by Allied air attacks on Kiel and was not operational again until late 1944. She spent most of the rest of the war escorting ships as the Germans evacuated East Prussia and bombarding Soviet forces. The ship was captured by the Allies in May 1945 and spent the rest of the year under British control as the Allies decided how to dispose of the captured German ships.
