Sinking of the armed merchant cruiser HMS Rawalpindi;

Around midday on 21 November 1939 the German battlecruisers Scharnhorst and Gneisenau, escorted by the light cruisers Köln and Leipzig and the destroyers Z 11 / Bernd von Arnim, Z 12 / Erich Giese and Z 20 / Karl Galster, departed Wilhelmshaven for a raid into the North Atlantic, this was to relieve the pressure of the pocket battleship Admiral Graf Spee operating in the South Atlantic. Late on the 21st the escorts left the battlecruisers.

Just after 1500 hours on 23 November the British armed merchant cruiser HMS Rawalpindi (Capt. E.C. Kennedy, (retired), RN) sighted the Scharnhorst. Rawalpindi was part of the British Northern Patrol and was stationed south-east of Iceland in the Iceland-Faroer gap. Captain Kennedy tried to outrun the German ship and reported to the Admiralty that he sighted the German pocket battleship Deutschland, still believed to be operating in the North Atlantic. Just after 1600 hours, Rawalpindi came within range of the Scharnhorst and was quickly reduced to a flaming wreck. During this engagement Scharnhorst was hit by a 6” shell from Rawalpindi causing only light damage. Scharnhorst and Gneisenau together picked up 27 survivors from Rawalpindi. Rawalpindi finally sank around 2000 hours.

The British light cruiser HMS Newcastle (Capt J. Figgins, RN), that was also part of the Northern Patrol, picked up Rawalpindi’s signal and closed the scene. She sighted the Gneisenau but the Germans managed to escape in the fog.

Of the ships of the Denmark strait patrol, the heavy cruisers HMS Suffolk (Capt. J.W. Durnford, RN) and HMS Norfolk (Capt. A.G.B. Wilson, MVO, DSO, RN) were ordered to proceed to the Bill Bailey Bank (to the south-west of the Faroers)

The light cruiser HMS Glasgow (Capt. F.H. Pegram, RN) escorted by the destroyers HMS Maori (Cdr. G.N. Brewer, RN) and HMS Zulu (Cdr. J.S.
