"At 20.58 hours on 29 March 1942 the unescorted Hertford (Master John Collier Tuckett) was hit by two torpedoes from U-571 about 200 miles south of Halifax. The ship was hit at 21.31 hours by a coup de grâce and sank four minutes later by the stern. Four crew members were lost. The master and 18 crew members landed at Liverpool, Nova Scotia. 21 crew members were picked up by the British steam merchant Glenstrae. 16 crew members and two gunners were picked up by the British steam merchant Fort Townsend and landed at Halifax."
