While returning to pick up wounded at the port of Le Havre, France, HMHS Salta struck a mine at 11:43, one mile (1.6 km) north of the entrance to the dam. A huge explosion smashed the hull near the stern in the engine room and hold number three. Water rushed into the disabled ship which listed to starboard and sank in less than 10 minutes. Of the 205 passengers and crew members, nine nurses, 42 member of the Royal Army Medical Corps (RAMC) and 79 crew drowned. The British patrol boat HMS P-26 attempted to come alongside to assist, but also struck a mine and sank.
