that some of the 8 officers and 21 men managed to get into a lifeboat and onto rafts, none of Margaret’s crew was ever seen again. In July 1942 the submarine operated in the Caribbean and torpedoed four ships: the British freighter Umtata on 7 July, the American tanker, J. A. Moffett, Jr. on 8 July, the Honduran freighter Nicholas Cuneo on 9 July and on 15 July the American tanker, Pennsylvania Sun. The whole crew of J. A. Moffett, Jr. (35 merchant marine and 5 Naval Armed Guard) abandoned ship into two lifeboats and three rafts, except for the master who was killed. The United States Coast Guard vessels Mary Jean and Southbound picked up the 39 survivors and brought them to Florida. When Pennsylvania Sun was torpedoed, two of the merchant crew died in the resulting explosion, but the rest of the 40 merchant marine crew and the 17 members of the Naval Armed Guard aboard survived after being rescued by . Pennsylvania Sun was later salvaged and returned to service, while the other three ships attacked in July were sunk. On 22 March 1943, U-571 was attacked by an aircraft in the North Atlantic and was damaged and had to return to base. In April 1943, Möhlmann claimed that he sank three additional ships but these could not be matched with records of Allied losses. On 22 April 1943, she had to return to base because the commander was badly injured in an accident on the conning tower. On 2 May 1943, Möhlmann was relieved by Oberleutnant zur See Gustav Lüssow. U-571 patrolled off the west coast of Africa in July before returning to base on 1 September. Between September and December, U-571 was probably being overhauled in a drydock as no mention of the boat for that time period appears in war diary kept by the German Commander in Chief, Submarines, Admiral Karl Dönitz. On 18 January 1944, Lüssow reported to his submarine command that he attacked and sank an unknown destroyer. This could not, however, be identified with any known Allied losses during World War II. Fate On 28 January 1944 she was attacked by an Australian-crewed Sunderland aircraft from No. 461 Squadron RAAF west of Ireland and was destroyed by depth charges. The aircraft's captain, Flight Lieutenant R. D. Lucas, reported that most of the crew successfully abandoned ship, but soon died from hypothermia.
