At 05.15 hours on 6 May 1941 the unescorted Surat (Master Thomas Edward Daniel) was hit by a stern torpedo from U-103 northwest of Freetown. The U-boat had spotted the ship, en route with 13 knots, at 16.03 hours the day before and only could keep up with her due to her zigzag course that also caused a first torpedo fired at 23.45 hours to miss. The crew apparently noticed the attack and evaded two torpedoes fired at 05.10 hours and a first stern torpedo five minutes later. The second stern torpedo fired shortly afterwards then hit the stern and stopped the ship, but also a first coup de grâce at 05.26 hours missed. The ship sank immediately after being hit amidships by two coups de grâce at 06.13 and 06.25 hours. Four crew members were lost. The master, 58 crew members and two gunners were picked up by the British hopper barge Foremost 102 and landed at Freetown.
