At 06.15 hours on 23 Sep, 1942, the unescorted Lindvangen (Master John Einar Jensen) was torpedoed on the starboard side between hatch #3 and the engine room by U-515 and sank by the stern after a boiler explosion in 30 fathoms of water. She sank so fast that no lifeboats could be launched, but the master and an able seaman had managed to get on a raft and were questioned by the Germans. They were picked up two hours later by the British examination vessel HMS Helene, which later also rescued another man in a gig, three men afloat in a big crate and two others clinging to various debris. On 29 September, all survivors were landed in Georgetown, British Guiana.
