U-510 torpedoes U.S. freighters George G. Meade, Mark Hanna, James Smith, Thomas Ruffin and James K. Polk at 07°11'N, 52°30'W. George G. Meade suffers no casualties to either her merchant crew or the Armed Guard, and returns to service; Mark Hanna is abandoned by most of the crew, submarine chaser PC-592 rescuing the men while a portion of the complement remains on board to prepare the ship to be towed; after repairs, she returns to active service. James Smith suffers the loss of six merchant sailors and five Armed Guard seamen in the initial explosion, and is partially abandoned, with submarine chaser PC-592 rescuing a portion of the crew. The ship, however, will be towed to Trinidad by British tug Zwarte Zee and will eventually re-enter active service. Thomas Ruffin is partially abandoned, with Courage and PC-592 rescuing crewmen (four of the ship's merchant complement and two of the 15-man Armed Guard are killed); the ship will eventually be written off as a total loss. James K. Polk (one Armed Guard sailor is killed when the ship is torpedoed--the only casualty) is partially abandoned, with PC-592 serving as the rescuing agent; the master and a volunteer crew rig tarpaulins and with those makeshift sails proceed some 360 miles.

German submarines attack convoy HX 228; U-221 torpedoes U.S. freighter Andrea F. Luckenbach at 51°04'N, 29°40'W.

U-757 administers the coup de grace to William C. Gorgas. German submarine U-255 torpedoes U.S. freighter Richard Bland, straggling from convoy RA 53, at 66°48'N, 14°15'W; the ship breaks in two.

Survivors include 3 Naval Armed Guards (see 25 January and 28 January). Destroyer Belknap (DD-251) rescues seven Armed Guard sailors, survivors from freighter Jonathan Sturges, along with three Dutch seamen from torpedoed motorship Madoera, both merchantmen the victims of U-707 on 23 February 1943 (see 6 April). Sole survivor of U.S. freighter Puerto Rican, torpedoed and sunk on 9 March by German submarine U-586 as the former straggled from convoy RA 53, is rescued by British trawler HMS St. Elstan. * 13 March, Sat. 1943 Pacific Submarine Sunfish (SS-281) sinks Japanese merchant cargo ship Kosei Maru near Tokara Jima, Ryukyus, 29°04'N, 129°17'E.

Atlantic German submarine U-167 attacks convoy UGS 6 and damages U.S. freighter Molly Pitcher about 500 miles west of Lisbon, Portugal, 38°21'N, 19°54'W; destroyer Champlin (DD-601) which, along with destroyer Rowan (DD-405) and merchantman William Johnson rescues survivors, attempts, unsuccessfully, to scuttle the crippled freighter with a torpedo. U-521 finishes off Molly Pitcher later the same day. Two of the 24-man Armed Guard and two merchant seamen perish in the sinking. German U-boat operations against convoy HX 229 continue: U-91 administers the coup de grace to U.S. freighters James Oglethorpe, torpedoed by U-758 the previous day, and the abandoned William Eustis, torpedoed the day before by U-435. Lost with the former are the 31 men who had remained on board. U-91 also torpedoes and sinks U.S. freighter Harry Luckenbach at 50°38'N, 34°46'W; British corvette HMS Pennywort is the only escort vessel that sights Harry Luckenbach's survivors but, already crammed with 108 men retrieved from other sunken ships from HX 229, is unable to recover them. Harry Luckenbach is thus lost with all hands (54 merchant sailors and a 26-man Armed Guard). U-600 torpedoes and sinks freighter Irenee Du Pont at 50°36'N, 34°30'W with the loss of 6 of the 26-man Armed Guard, 1 of 9 Navy passengers and six of the 49-man merchant complement; Dutch merchantman Tekoa rescues 55 survivors, Canadian destroyer HMCS Mansfield 16 (one of whom dies of wounds). British corvette HMS Anemone fails to scuttle Irenee Du Pont with gunfire and a depth charge; it thus falls to U-91 to finish off the battered "Liberty." * 18 March, Thu. 1943 Atlantic * 19 March, Fri.
