At 22.52 hours on 22 May 1941 the unescorted British Grenadier (Master Henry George Jeary) was hit amidships by one torpedo from U-103 while steaming on a zigzag course southwest of Freetown. The ship stopped and was then hit amidships by a coup de grâce, but remained afloat. At 23.59 hours, the U-boat fired a second coup de grâce that hit in the engine room, causing the tanker to settled slowly by the stern. The British Grenadier was left in a sinking condition and later foundered in 06°20N/12°50W. The master, 22 crew members and two gunners were picked up by the Ganda and 24 crew members were rescued by the Spanish tanker Jose Calvo Sotelo and landed at Freetown.
