would not actually be declared until 12 August, and the order was countermanded four hours later, but Milne gave up the hunt for Goeben, following his standing orders to guard the Adriatic against an Austrian break-out attempt. On 9 August, Milne was given clear orders to "chase Goeben which had passed Cape Matapan on the 7th steering north-east." Milne still did not believe that Souchon was heading for the Dardanelles, and so he resolved to guard the exit from the Aegean, unaware that the Goeben did not intend to come out. On 3 November 1914, Winston Churchill, then First Lord of the Admiralty, ordered the first British attack on the Dardanelles following the commencement of hostilities between Ottoman Turkey and Russia. The attack was carried out by Indomitable and Indefatigable, as well as the French pre-dreadnought battleships and . The intention of the attack was to test the fortifications and measure the Turkish response. The results were deceptively encouraging. In a twenty-minute bombardment, a single shell struck the magazine of the fort at Sedd el Bahr at the tip of the Gallipoli peninsula, displacing (but not destroying) 10 guns and killing 86 Turkish soldiers. The most significant consequence was that the attention of the Turks was drawn to strengthening their defences, and they set about expanding the mine field. This attack actually took place before Britain's formal declaration of war against the Ottoman Empire on 6 November. Indefatigable remained in the Mediterranean until she was relieved by Inflexible on 24 January 1915 and proceeded to Malta for a refit; she then sailed to England on 14 February and joined the 2nd BCS upon her arrival. The ship conducted uneventful patrols of the North Sea for the next year and a half. She was the temporary flagship of the 2nd BCS during April–May 1916, while her half-sister was under repair after colliding with Indefatigables other half-sister . Battle of Jutland On 31 May 1916, the 2nd BCS consisted of New Zealand (flagship of Rear-Admiral William Pakenham) and Indefatigable. The squadron was assigned to Admiral Beatty's Battlecruiser Fleet which had put to sea to intercept a sortie by the High Seas Fleet into the North Sea. The British were able to decode the German radio messages and left their bases before the Germans put to sea. Admiral Franz von Hipper's battlecruisers spotted the Battlecruiser Fleet to their west at 15:20, but Beatty's
