Location of battle


Following the German Navy's successful raid on the Scandinavian convoy on 17 October 1917, Admiral Sir David Beatty, Commander-in-Chief of the British Grand Fleet, was determined to retaliate. On 17 November 1917 a strong force of cruisers under Vice Admiral Trevylyan Napier was sent to attack German minesweepers, which were clearing a channel through British minefields in the Heligoland Bight. The intentions of the German force had been revealed by British Naval Intelligence, allowing the British to mount an ambush.[1] The German sweepers were escorted by a group of cruisers and torpedo-boats under Rear Admiral Ludwig von Reuter.

The battle

The action began at 7.30 a.m., roughly 65 nautical miles west of Sylt, when HMS Courageous sighted the enemy. She opened fire at 7:37 a.m. Admiral Reuter, the German commander, with four light cruisers and eight destroyers, [Note 1] advanced to engage the Royal Navy units in order to cover the withdrawal of his minesweepers, all of which escaped except for the trawler Kehdingen,(GE) which was sunk. The battle thereafter developed into a stern chase as the German forces, skillfully using smoke-screens, withdrew south-east at their best speed, under fire from the pursuing British ships of the 1st Cruiser Squadron, the 1st and 6th Light Cruiser Squadrons, and, later, HMS Repulse (which had been detached from the 1st Battle Cruiser Squadron and came up at high speed to join the battle). Both sides were hampered in their maneuvers by the presence of naval minefields.

At about the same time, the light cruisers came under fire from two German Kaiser-class battleships, SMS Kaiser and SMS Kaiserin which had come up in support of Reuter's ships; HMS Caledon was struck by one 30.5 cm (12.0 in) shell which did minimal damage; shortly thereafter, the British ships gave up the chase as they reached the edge of known minefields.

All personnel on the bridge of the light cruiser HMS Calypso, including her captain, Herbert Edwards, were killed by a 15 cm (5.9 in) shell.[Note 2] The battle cruiser HMS Repulse briefly engaged the German ships at about 10:00,[2] scoring a single hit on the light cruiser SMS Königsberg that ignited a major fire on board.[3]

It was during this battle that Able Seaman John Henry Carless of HMS Caledon won a posthumous Victoria Cross for his bravery in manning a gun despite mortal wounds.[4]

  1. two of the German destroyers were initially detached, but rejoined during the battle
  2. There is some dispute as to whether it was a 15cm or 30.5cm shell which damaged HMS Calypso; since she was hit at 9.40 a.m. (see Newbolt, op. cit., p.175), before the German battleships opened fire, the former is the more likely.
  3. Other forces at sea in support (none of which were engaged):
    Battle Cruiser Force (Vice Admiral Sir William Pakenham KCB, KCVO): Lion (flag), Princess Royal, Tiger, New Zealand; attached light forces (13th Destroyer Flotilla): Champion (flotilla cruiser), Verdun, Telemachus, Oriana, Nepean , Obdurate, Tristram, Petard, Tower.
    1st Battle Squadron (Admiral Sir Charles Madden): Revenge (flag), Royal Oak, Resolution, Emperor of India, Benbow, Canada; attached destroyers (12th Destroyer Flotilla): Saumarez (flotilla leader), Valhalla (flotilla leader), Noble, Nonsuch, Napier, Penn, Paladin, Prince, Mischief, Munster, Narborough.
  4. Repulse, which was faster and of shallower draft than the other British battle cruisers, was detached from Pakenham's group in order to support the 1st Light Cruiser Squadron, c.8.0am; she came into action c. 9.0am and scored a 15-inch hit on Königsberg at 9.58am, the end of the engagement.
  5. Other forces at sea in support (none of which were engaged):
    battleships: Friedrich der Grosse, König Albert; battlecruisers: Hindenburg, Moltke.
  6. The German Navy's large torpedo boats (großer torpedoboote) were of similar size and function to the destroyers in the Royal Navy, and are often referred to as such.
