Elisabeth van Belgie, Sveve & F.J. Wolfe

Between 16:31 and 16:33 U-96 fired four torpedoes at four ships and hit three. The 4,241-ton Belgian merchant ship Elisabeth van Belgie sank with the loss of one man from her crew of 56.^[7] When Sveve, a 6,313-ton Norwegian tanker in Admiralty service as a Royal Fleet Auxiliary was hit the subsequent explosion destroyed bulkheads, opened holes on the starboard side, and wrecked the steering gear. With the ship immobile and flooding, the 37 crew and two gunners abandoned ship in four lifeboats. They were picked up within the hour by HMCS Sherbrooke, which then attempted to scuttle the wreck with shell fire. Eventually the ship was reboarded by four of the crew and four men from the corvette who succeeded in sinking her.^[8] The third ship hit, the 12,190-ton British tanker F.J. Wolfe was damaged, but able to continue with the convoy.^[9]

Empire Oil

U-659 attacked south-west of Iceland, at 21:10 on 10 September, and hit the 8,029-ton British tanker Empire Oil with two torpedoes, stopping her. All her crew of 53 survived, as the master, 12 crewmen and 6 gunners were picked up by HMCS St. Croix, and 29 crewmen and 5 gunners by HMCS Ottawa. At 01:47 the next day, U-584 sank the drifting Empire Oil with two more torpedoes.^[10] After her strike U-659 was counter-attacked by the convoy escorts and seriously damaged. She was forced to abort the patrol and returned to France.^[11]

Marit II

At 00:16 on 11 September U-404 fired three torpedoes and one hit the 7,417-ton Norwegian tanker Marit II. U-608 also fired torpedoes at 00:20 and claimed a hit. Marit II stopped, but after inspecting the damage, she continued and rejoined the convoy on 12 September. She was later repaired in New York and returned to service in February 1943.^[12]

Fjordaas

U-218 fired five torpedoes between 01:35 and 01:40 on 11 September, and struck the 7,361-ton Norwegian tanker Fjordaas on the port side amidships opening a 30-by-60-foot (9.1 by 18.3 m) hole. The crew abandoned ship in two lifeboats, but remained close by as the master, first mate and chief engineer inspected the damage. Her engines and steering gear were intact, so the crew boarded and managed to take her back to Glasgow, arriving on 15 September.^[13]

Delães

At 11:50 on 11 September U-96 attempted to stop the 415-ton neutral Portuguese three-masted fishing schooner Delães by firing three shots from her deck gun across her bow. U-96 then sank the vessel with shells when it did not stop. The Germans claimed to see no neutrality markings, that it had steered a suspicious course close to convoy ON-127, and believed they heard ASDIC signals from the ship. All 54 of the crew survived.^[14]

Hindanger

At 19:25 hours on 11 September the 4,884-ton Norwegian merchant ship Hindanger was torpedoed by U-584. One man was killed, and the rest of the crew of 41 abandoned ship. The survivors were picked up by HMCS Amherst, which reported that she sank the wreck with gunfire and a depth charge at 23:12. However, it is possible that the scuttling was unsuccessful, and the ship was actually sunk at 05:34 hours on 12 September by two torpedoes by U-608.^[15]

Daghild

At 06:17 on 12 September U-404 fired three torpedoes, and struck the 9,272-ton Norwegian tanker Daghild with one, making a hole 50-by-54-foot (15 by 16 m) in her side. However, she reached St. John's for repairs, and then proceeded to New York for further work.^[16]

Empire Moonbeam & Hektoria

At 01:05 on 12 September, U-211 fired torpedoes, and damaged two British ships; the 6,849-ton merchant ship Empire Moonbeam was hit once, and the 13,797-ton whale factory ship Hektoria twice. Both vessels were sunk by U-608 later that day. Hektoria was sunk at 03:51 with the loss of one crewman, while the master, 76 crewmen and eight gunners were picked up by HMCS Arvida. Empire Moonbeam was sunk at 04:59 with the loss of three of her crew, while the master, 44 crewmen, six gunners and one passenger were also picked up by Arvida.^[17][18]

Stone Street

At 14:36 on 13 September U-594 fired a spread of three torpedoes at the 6,131-ton merchant ship Stone Street, owned by the Waterman Steamship Corporation of Mobile, Alabama, but sailing under the Panamanian flag. The ship was about 12 nautical miles (22 km) from the main convoy having developed problems with her boilers. One torpedo hit the ship in the engine room, and she listed and finally sank at 15:50. The master, 39 crewmen and 12 armed guards abandoned ship in a lifeboat and raft. Eleven crewmen and two armed guards were lost. The U-boat surfaced and took the survivors on board to be questioned, and provided them with supplies of whiskey, food, cigarettes and matches before returning all but the master (who was kept as a prisoner) to their lifeboats. They were picked up on 19 September by the merchant ship Irish Larch.^[19]

HMCS Ottawa

At 02:05 on 14 September U-91 fired two torpedoes at a destroyer and observed a hit. Then they saw another destroyer, made a full circle, and fired another torpedo at 02:15, which hit amidships and caused the ship to explode and sink immediately. They thought that they had sunk two destroyers, but in fact it was HMCS Ottawa, which was hit twice. Only 67 of her crew of 181 survived.

By now though the convoy was within range of aircraft from Newfoundland and the escorts were reinforced by the destroyers HMCS Annapolis and HMS Witch, forcing the U-boats break off their attacks and disperse.^[6]
