  5 March, Fri. 1943

Pacific
Battle of Bismarck Sea concludes, although attacks on survivors found on rafts and in landing barges ("grim and bloody work for which the crews had little stomach") continue over the ensuing days by Allied aircraft and U.S. motor torpedo boats. Failure of that operation, Japanese navy officials admit later, proves "the impossibility of surface transport in the Lae area." Of the sixteen ships which sail for Lae, all eight transports are sunk, as are four of the escorting destroyers. Motor torpedo boats PT-143 and PT-150, patrolling 25 miles northeast of Cape Ward Hunt, New Guinea, in the wake of the battle, encounter a Japanese submarine rescuing survivors of the engagement and force her to submerge.

Battle to protect convoy SC 121 continues (see 6 March 1943) as Coast Guard cutters Bibb (WPG-31) and Ingham (WPG-35) and destroyer Babbitt (DD-128) reinforce the escorts. Babbitt proves her worth this day as she helps keep U-boats down. Despite the efforts of the escorts, however, German submarine U-409 torpedoes U.S. freighter Malantic at 59°30'N, 24°00'W, which is abandoned in a gale; 19 merchant seamen, five Armed Guard sailors and the ship's sole passenger perish in the attempt to reach British rescue vessel Melrose Abbey. Malantic will sink the next day.

German submarine U-510 carries out series of attacks on ships of convoy BT 6, which is escorted by destroyer Borie (DD-215), gunboats Courage (PG-70) and Tenacity (PG-71) and two submarine chasers, off Cayenne, French Guayana. 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. Eventually towed to Trinidad and thence to Mobile, Alabama, James K. Polk will be written off as a total loss.

U.S. freighter Puerto Rican, straggling from convoy RA 53, is torpedoed and sunk by German submarine U-586 at 66°44'N, 10°41'W'; of the 40-man merchant complement and 25-man Armed Guard, only one man of the former will survive the abandonment in the below-freezing environment in which the sinking takes place (see 12 March).

U-444 torpedoes freighter William C. Gorgas at 51°35'N, 28°30'W; British destroyer HMS Harvester rescues the 27-man Armed Guard and 33 of the 43-man merchant complement, but is herself later torpedoed and sunk by U-432. Ultimately, only four Armed Guard sailors and eight merchant seamen from William C. Gorgas survive Harvester's sinking, rescued by Free French-manned British corvette HMS Aconit. 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. During the abandonment in rough seas, 17 of the 26-man Armed Guard and 19 of 42-man merchant complement perish. Survivors are rescued (27 by British destroyer HMS Impulsive); the forward portion of the ship is eventually towed to Iceland and salvaged.

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."

German U-boat onslaught against Atlantic convoys continues: U.S. freighter Mathew Luckenbach departs convoy HX 229, believing her chances greater of completing the voyage independently than in company with other ships, but runs afoul of U-527 in the vicinity of SC 122. U-527 torpedoes Mathew Luckenbach at 54°20'N, 25°07'W; Coast Guard cutter Ingham (WPG-35) rescues the freighter's entire complement (42 merchant sailors and a 26-man Armed Guard). Subsequently, U-523 administers the coup de grace to Mathew Luckenbach. With the loss of Mathew Luckenbach and Greek freighter Carras (a straggler from SC 122) to U-533 on this date, German U-boats will break off operations against SC 122 and HX 229 and conclude what is regarded as the largest convoy battle of the war. Despite the valiant efforts of the escorts, the merchantmen suffer heavy losses.

U.S. cruiser and destroyer gunfire stops German tank attack on landing beaches near Gela, Sicily; Army observers report 13 of the 50 tanks that make the attack are destroyed. Off the invasion beaches at Sicily, enemy air attacks account for damage to tank landing ships LST-158 off Licata (she is then beached and abandoned), 37°05'N, 13°55'E (LST 318, beached adjacent to her burning sistership, retracts immediately to avoid damage from exploding ammunition and gasoline); attack transport Barnett (APA-5) and transport Orizaba (AP 24); near-misses damage transport Monrovia (AP-64), 37°02'N, 14°15'E, and attack transport Joseph T.

Off Gela, Sicily, U.S. freighter Robert Rowan is set afire by bomb during German air attack, and is abandoned. Once the blaze reaches her ammunition cargo, the freighter then explodes. Destroyer McLanahan (DD-615) attempts to sink Robert Rowan with gunfire to extinguish the flames from the burning vessel that are illuminating all ships within miles, but the attempt is frustrated because the water is too shallow and the abandoned merchantman will not sink. Navy landing craft and transport Orizaba, however, rescue all hands: 41-man merchant complement, 32-man Armed Guard and 348 troops.

The escort carrier USS Liscome Bay, with 916 crewmen on board, was torpedoed and sunk by the Japanese submarine I-175. The torpedo had made a direct hit on the aircraft bomb stowage compartment on the ship's starboard side, causing a massive explosion that incinerated most of the men below decks, and the ship sank within 23 minutes. In all, 644 men were killed — 53 officers and 591 enlisted men.
Escort carrier Liscome Bay (CVE-56) is sunk by Japanese submarine I-175, Gilberts, 02°34'N, 172°30'E.

German planes bomb Allied shipping at Bari, Italy, sinking and damaging a number of U.S. freighters moored there. John M. Schofield and Grace Abbott are damaged by flying fragments (the latter also by a dud bomb); the former suffers no casualties among the 44-man merchant complement, 28-man Armed Guard and an indeterminate number of British Army stevedores on board to work cargo while the latter has only one merchant seaman wounded from among her 41-man civilian and 28-man Armed Guard complement. Samuel J. Tilden is hit by two bombs and catches fire; 17 of the 209 embarked troops perish as the soldiers abandon ship. The 41-man merchant crew and the 28-man Armed Guard remain at their posts to battle the blaze that eventually burns out of control and forces her crew off the ship. Ten of the ship's civilian complement die in the conflagration (see 3 December 1943). John L. Motley, carrying a cargo of ammunition, is hit by at least three bombs; direct hits and near-misses set nearby John Bascom afire; four of 44 merchant seamen perish as do 10 of 28 Armed Guard sailors. The survivors, in addition to one passenger, abandon ship as the flames burn out of control. Her mooring lines burnt through, John Bascom drifts near the burning John L. Motley, which explodes, killing all on board (42 of the 46-man merchant complement and 22 of the 29-man Armed Guard) (the only survivors are on shore at the time of the attack and thus escape the fate of their shipmates). Debris from John L. Motley damages gasoline tanker Aroostook (AOG-14), 41°06'N, 16°52'E, and sets fire to Lyman Abbott. John Harvey, moored originally between John L. Motley and Joseph Wheeler, is showered by burning debris, and catches fire herself, drifting into the harbor where she explodes, showering debris on the unfortunate Lyman Abbott. Tragically, John Harvey's cargo includes mustard gas which subsequently kills and injures many of the local inhabitants, in addition to harming many among the 42 merchant seamen and 29 Armed Guards on board Lyman Abbott. Consequently, 2 of the ship's civilian crew and one Armed Guard sailor, in addition to the ship's sole passenger, succumb to shrapnel wounds or mustard gas burns. Joseph Wheeler is hit by one bomb that touches off her ammunition cargo and the ship disintegrates, killing all on board: 15 of 41 merchant seamen and 13 of the 28-man Armed Guard, in addition to the single passenger, perish in the cataclysmic blast. Fifteen Armed Guard sailors and 26 merchant sailors escape the fate of their shipmates only because they were away from the ship, on shore, when she explodes.

The latter's commander and nine men, however, stay with the ship, manning the 5-inch gun aft. U-193's third torpedo finishes off the tanker, though, and she sinks, taking nine of the ten Armed Guards who manage to reach a raft (they are swept off as the ship goes under), as well as the detachment commander, down with her (see 5 and 6 December 1943).
