SMS Blücher

1915

Dogger Bank, capsized under cheering gunners Location: North Sea, Dogger Bank · Coordinates: 54.53°N 4.25°E · Casualties: 792 · Survivors: 234 · Depth: 40 m · Cause: naval gunfire — Engaged by British battlecruisers Lion, Tiger, Princess Royal, and New Zealand at the Battle of Dogger Bank on 24 January 1915. Struck by over seventy shells; she listed progressively, then capsized while still returning fire. Sank at 12:07. · Fate: war grave · dispersed · Type: armoured cruiser · Tonnage: 17,500 tons · Crew: 1026 · Flag: German Empire · Launched: 1908 German armoured cruiser, the fastest of her class, caught by the British battlecruiser force at the Battle of Dogger Bank on 24 January 1915. Struck by over seventy British shells across three hours, she listed progressively, burning, but kept firing. She capsized at 12:07 while still shooting; the photograph of her rolling belly-up with her crew scrambling along her keel became the iconic image of naval firepower in the Great War. 792 dead; the British rescue effort was abandoned when a Zeppelin was mis-identified as a bombing attack. The Vessel SMS Blücher was a German armoured cruiser of the Imperial German Navy, built at the Kaiserliche Werft Kiel between 1906 and 1909 and commissioned on 1 October 1909. She was 162 metres long, 17,500 tons displacement, and armed with twelve 21-centimetre primary guns in six twin-gun turrets (one forward, one aft, and four in wing positions), eight 15-centimetre secondary guns in casemate positions, and four 45-centimetre torpedo tubes. Her armour protection included a 180-millimetre main belt of Krupp cemented armour, 180-millimetre turret face armour, and 70-millimetre deck armour. Blücher was a unique design representing a specific historical transition in capital-ship naval architecture. She had been designed in 1905-1906 in response to German naval intelligence reports that the Royal Navy was designing an armoured cruiser armed with 23.4-centimetre primary guns; her 21-centimetre armament was specifically sized to match this assumed British armament. In fact, the Royal Navy's new design was the battlecruiser HMS Invincible armed with 30.5-centimetre primary guns; the German intelligence assessment had been substantially incorrect, and Blücher was built as a substantially underarmed ship relative to the actual British battlecruiser class. The specific consequence was that SMS Blücher, at her commissioning in 1909, was an operationally marginal capital ship: substantially more heavily armed than the older German armoured cruisers (which she was intended to replace) but substan The Disaster The pursuing engagement - subsequently designated the Battle of Dogger Bank - lasted approximately four hours, from 08:00 to 12:00 on 24 January 1915. The tactical configuration was a classic stern-chase: the faster British battlecruiser squadron (27 knots maximum speed) was pursuing the retreating German force (25 knots maximum speed). The critical tactical consideration was the position of SMS Blücher, the slowest ship in the German formation. Blücher's maximum speed of 25 knots was slower than the other three German battlecruisers (Seydlitz, Moltke, Derfflinger all capable of 27-28 knots). As the pursuing British squadron closed the range, Blücher progressively fell behind the main German formation and became the British squadron's primary target. By 09:00, Blücher was approximately 2 kilometres behind the nearest other German ship; by 10:00, the separation had widened to approximately 4 kilometres. The British battlecruisers concentrated their fire on Blücher from approximately 09:30. The progressive shell damage to the Austro-trailing German ship was substantial: British 34-centimetre and 30.5-centimetre shells progressively destroyed Blücher's gun turrets, compromised her steering, and initiated multiple internal fires. By 11:00, Blücher was effectively disabled: her primary armament was substantially inoperative, her speed was reduced to approximately 17 knots, and she was taking on water through multiple hull breaches.
