The USS Leopold was an Edsall-class destroyer escort built for the United States Navy during World War II. Departing New York on March 1 on her second voyage, Leopold took her screening station as part of a 27-ship convoy bound for the British Isles. On the 8th, she reported an HF/DF intercept which indicated an enemy submarine on the route of the convoy. The route was consequently altered. On March 9, while south of Iceland, she reported a radar contact at 1950 at 8,000 yd, which placed it 7 miles south of the convoy in position 57°37’0?N 26°30’0?W? / ?57.616667°N 26.5°W? / 57.616667; -26.5. Assisted by the destroyer escort Joyce, Leopold was ordered to intercept. General Quarters was sounded and orders were issued to fire on sight. A flare was released and gun crew strained to sight the submarine in the lighted area. The U-boat was almost submerged when spotted and the gun crews had to work blind. Leopold was struck by an acoustic torpedo fired from the German submarine U-255. Badly damaged, she was abandoned. Joyce rescued 28 survivors at the close of the action; 171 others were lost through explosion on board or drowning after abandoning. Leopold remained afloat until early the next morning, then sank just south of Iceland.
