At 09.09 hours on 10 March 1943, U-185 attacked convoy KG-123 for a second time southeast of Guantanamo Bay and torpedoed the James Sprunt (Master Elie Constantine Carr) on her maiden voyage in station #42. The ship had shifted out of position between the third and fourth columns. One torpedo struck the vessel and caused her cargo to explode, the ship completely disappeared in 30 seconds. The blast went straight up and sent debris over the entire convoy and was so large that a ship 40 miles away witnessed it. None of the eight officers, 36 crewmen and 25 armed guards (the ship was armed with one 5in and nine 20mm guns) survived.
