German Junkers Ju 87 Stuka dive bombers sank Grenade as she evacuated Allied troops during Operation Dynamo on 29 May 1940.

Grenade carried a maximum of 470 long tons (480 t) of fuel oil that gave her a range of 5,530 nautical miles (10,240 km; 6,360 mi) at 15 knots (28 km/h; 17 mph).

[2] Grenade was laid down by Alexander Stephen and Sons in Glasgow, Scotland on 3 October 1934, launched on 12 November 1935 and completed on 28 March 1936.

After returning home to give her crew leave and be refitted in Chatham Dockyard between 27 May and July 1938, the ship was then briefly transferred to the Red Sea in October 1938.

[4] When World War II began in September 1939, Grenade was in Alexandria, but she, and her entire flotilla, was transferred to the Western Approaches Command at Plymouth in October.

Grenade received permanent repairs in Harwich from 2 March to 3 April and was assigned to Home Fleet at Scapa Flow after their completion.

[7] For the rest of the month Grenade escorted the battleship Warspite and the aircraft carrier Ark Royal in Norwegian waters.
