At 07.43 hours on 13 Apr, 1941, HMS Rajputana (F 35) (Capt F.H. Taylor, DSC, Rtd, RN) was hit by one torpedo from U-108 west of Reykjavik. She had been the ship of the convoy commodore Cdr C.T.O. Richardson in convoy HX-117 but was then dispatched to patrol the Strait of Denmark.

The armed merchant cruiser had been first spotted by the U-boat at 09.45 hours on 11 April and was followed while she was patrolling on a zigzag course at high speed and sometimes making 180° turns. The chase was hampered by problems with the periscope, pack ice and snow. A first spread of two torpedoes fired at 18.08 hours on 11 April missed like the next two torpedoes fired at 20.46 and 20.48 hours on 12 April. A fifth torpedo at 07.40 hours on 13 April missed, but the sixth at 07.43 hours hit in the stern and caused a fire on the ship, which then fired at the periscope. A first coup de grâce at 08.23 hours malfunctioned, but the next torpedo at 09.30 hours struck in the after part and caused the ship to sink by the stern with a list to port. The commodore, four officers and 35 ratings were lost. 283 survivors were picked up by HMS Legion (F 74) (Cdr R.F. Jessel, RN) and landed at Reykjavik.
