Example Input: The Crimean campaign opened in September 1854. 360 ships sailed in seven columns, each steamer towing two sailing ships.:422 Anchoring on 13 September in the bay of Eupatoria, the town surrendered and 500 Marines landed to occupy it. This town and bay would provide a fall back position in case of disaster.:201 The ships then sailed east to make the landing of the allied expeditionary force on the sandy beaches of Calamita Bay on the south west coast of the Crimean Peninsula. The landing surprised the Russians, as they had been expecting a landing at Katcha; the last minute change proving that Russia had known the original battle plan. There was no sign of the enemy and the men were all landed on 14 September. It took another four days to land all the stores, equipment, horses and artillery.
Example Output: In what year did the Crimean campaign open?

Example Input: All Greeks were united, however, in their determination to liberate the Greek-speaking provinces of the Ottoman Empire, regardless of the dialect they spoke. Especially in Crete, a prolonged revolt in 1866–1869 had raised nationalist fervour. When war broke out between Russia and the Ottomans in 1877, Greek popular sentiment rallied to Russia's side, but Greece was too poor, and too concerned of British intervention, to officially enter the war. Nevertheless, in 1881, Thessaly and small parts of Epirus were ceded to Greece as part of the Treaty of Berlin, while frustrating Greek hopes of receiving Crete.
Example Output:
War between Russia and the Ottomans began in what year?
