At 03.56 hours on 21 Dec 1942 the unescorted Montreal City (Master Edward Roylands Wolferstan Chanter), a straggler from station #11 in convoy ON-152, was hit aft by one stern torpedo from U-591 about 600 miles east-northeast of St. John’s, Newfoundland. The U-boat had spotted the ship in bad weather about 15 minutes earlier and missed her with a spread of three torpedoes at 03.50 hours. The crew was observed to abandon ship in three lifeboats after an emergency message was sent and received by other ships of convoy. At 04.09 hours, a coup de grâce was fired because the vessel only settled slowly by the stern. The torpedo struck the Montreal City amidships and caused her to sink by the stern within two minutes, leaving behind a debris field containing several hundred empty gasoline canisters. The Germans then questioned the occupants in one of the lifeboats before leaving the area. However, the survivors were never seen again: the master, 32 crew members and seven gunners were lost.
