At 14.36 hours on 13 Sep 1942, U-594 fired a spread of three torpedoes at the Stone Street (Master Harald Anderson) and reported two hits. She had been at position #13 in convoy ON-127, but was ordered out due to its continual smoking and straggling because of boiler troubles. One torpedo hit in the engine room on the port side and another barely missed the bow when the ship was about 12 miles starboard of convoy. The ship developed a 45° list to port with the engines and screw still running and sank at 15.50 hours. No distress signals could be sent and the master, 39 crew members and twelve armed guards abandoned ship in one lifeboat and a raft. Eleven crew members and two armed guards were lost. The U-boat surfaced and accidentally capsized the lifeboat, but the men were taken aboard, questioned, provided with supplies (whiskey, food, cigarettes and matches) and placed them on two rafts except for the master who was taken prisoner. The survivors righted the lifeboat and were picked on 19 September by the steam merchant Irish Larch in position 48°50N/40°00W and were landed three days later at St. John, New Brunswick.
