At 0304, US Liberty ship Jeremiah Van Rensselaer in station #45 (last ship in the extreme port column) of Convoy HX-224 was torpedoed by U-456. The ship had been in station #11, but had performed poorly keeping station and kept her station about once in seven nights, she managed to catch up in the daytime and consequently her position was changed.

Two torpedoes struck on the port side in the #1 hold. The explosion created a hole 8 feet by 30 feet, blew the hatch cover off, spewed cargo overboard and started a fire. A short time later, a third torpedo struck on the port side at #4 hatch and blew a truck standing on deck into the water and also started a small fire. The engines were secured and some of the eight officers, 34 crewmen, 28 armed guards (the ship was armed with one 4in, one 3in and eight 20mm guns) and one passenger abandoned ship. Panicking, they tried to launch three lifeboats, but two capsized in the rough seas. Eight men got away in a boat and others jumped overboard and swam to three rafts, but the harsh weather and cold water caused the most men to die from exposure. Only one officer, six crewmen and 17 armed guards survived. 23 survivors and three bodies were picked up after five hours by the British rescue ship Accrington and landed at Gourock. A boarding party from USCGC Ingham later boarded the ship and noted that she could have been saved, but the watch below left the boilers fire lit, which burned the boilers out. The vessel was scuttled by gunfire at 1300. The boarding party also found one man whom never left the ship and took him to the escort vessel. One week later two bodies were recovered from a raft by the French corvette Lobelia.
