Passage: On 29 October Yavuz bombarded Sevastopol in her first operation against Imperial Russia, though the Ottoman Empire was not yet at war with the Entente; Souchon conducted the operation to force Turkey into the war on the side of Germany. A 25.4 cm (10 in) shell struck the ship in the after funnel, but it failed to detonate and did negligible damage. Two other hits inflicted minor damage. The ship and her escorts passed through an inactive Russian minefield during the bombardment. As she returned to Turkish waters, Yavuz came across the Russian minelayer Prut which scuttled herself with 700 mines on board. During the engagement the escorting Russian destroyer Lieutenant Pushkin was damaged by two of Yavuz's secondary battery 15 cm (5.9 in) shells. In response to the bombardment, Russia declared war on 1 November, thus forcing the Ottomans into the wider world war. France and Great Britain bombarded the Turkish fortresses guarding the Dardanelles on 3 November and formally declared war two days later. From this engagement, the Russians drew the conclusion that the entire Black Sea Fleet would have to remain consolidated so it could not be defeated in detail (one ship at a time) by Yavuz.Yavuz, escorted by Midilli, intercepted the Russian Black Sea Fleet 17 nautical miles (31 km; 20 mi) off the Crimean coastline on 18 November as it returned from a bombardment of Trebizond. Despite the noon hour the conditions were foggy and none of the capital ships were spotted initially. The Black Sea Fleet had experimented with concentrating fire from several ships under the control of one "master" ship before the war, and Evstafi held her fire until Ioann Zlatoust, the master ship, could see Yavuz. When the gunnery commands were finally received they showed a range over 4,000 yards (3,700 m) in excess of Evstafi's own estimate of 7,700 yards (7,000 m), so Evstafi opened fire using her own data before Yavuz turned to fire its broadside. She scored a hit with her first salvo as a 12-inch shell partially penetrated the armor...
