At 21.33 hours on 18 February 1941 the unescorted Seaforth (Master Walter Minns) was hit amidships by one torpedo from U-103 about 300 miles south of Iceland and sank quickly after being hit in the stern by a coup de grâce at 21.50 hours. The ship had been spotted in heavy seas at 13.55 hours and missed by a first torpedo at 21.30 hours. The U-boat observed that lifeboats were launched after the first hit, but the master, 46 crew members, two gunners and nine passengers were lost.
