for Hipper. The light cruiser spotted the light cruiser and signalled a report to Beatty. At 12:30 Beatty turned his battlecruisers towards the German ships. Beatty presumed that the German cruisers were the advance screen for Hipper's ships, however, those were some 50 km (31 mi) behind. The 2nd Light Cruiser Squadron, which had been screening for Beatty's ships, detached to pursue the German cruisers, but a misinterpreted signal from the British battlecruisers sent them back to their screening positions. This confusion allowed the German light cruisers to escape, and alerted Hipper to the location of the British battlecruisers. The German battlecruisers wheeled to the northeast of the British forces and made good their escape. Battle of Dogger Bank On 23 January 1915, a force of German battlecruisers under the command of Admiral Franz von Hipper sortied to clear the Dogger Bank of any British fishing boats or small craft that might be there to collect intelligence on German movements. However, the British were reading their coded messages and sailed to intercept them with a larger force of British battlecruisers under the command of Admiral Beatty. Contact was initiated at 07:20 on the 24th when the British light cruiser Arethusa spotted the German light cruiser . By 07:35 the Germans had spotted Beatty's force and Hipper ordered a turn to the south at , believing that this would suffice if the ships that he saw to his north-west were British battleships and that he could always increase speed to 's maximum speed of if they were British battlecruisers. Beatty ordered his battlecruisers to make all practicable speed to catch the Germans before they could escape. The leading ships, Lion, her sister and , were doing in pursuit and Lion opened fire at 08:52 at a range of . The other ships followed a few minutes later but, hampered by the extreme range and decreasing visibility, they did not score their first hit on Blücher until 09:09. The German battlecruisers opened fire themselves a few minutes later at 09:11, at a range of , and concentrated their fire on Lion. They first hit her at 9:28 on the waterline with a shell that flooded a coal bunker. Shortly afterwards a shell from Blücher hit the roof of 'A' turret, denting it and knocking out the left gun for two hours. At 09:35 Beatty signalled 'Engage the corresponding ships in the enemy's
