Berehaven. Beatty described Tiger to the First Sea Lord, Admiral of the Fleet Lord Fisher of Kilverstone, as "not yet fit to fight. Three out of her four dynamoes are out of action for an indefinite period, and her training is impeded by bad weather, which might continue for many weeks at this time of year, and at present is quite unprepared and inefficient." 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 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 this would suffice if the ships 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, , and Tiger, 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. At 09:35, Beatty signalled "Engage the corresponding ships in the enemy's line", but Captain Pelly, believing that was already engaging Blücher, fired at , as did Lion, which left free to continue attacking Lion without risk. In the meantime, Blücher had been heavily damaged by fire from all the other battlecruisers; her speed had dropped to and her steering gear had been jammed. Beatty ordered Indomitable to attack her at 10:48. Six minutes later, Beatty spotted what he thought was a submarine periscope on the starboard bow and ordered an immediate 90° turn to port to avoid the submarine, although he failed to hoist the "Submarine Warning"
