Question: What date did the battle that killed Christopher Cradock begin? Passage 1:Sir Christopher "Kit" George Francis Maurice Cradock (2 July 1862 – 1 November 1914) was a British Rear-Admiral of the Royal Navy. He earned a reputation for great gallantry. Appointed to the royal yacht, he was close to the British royal family. Prior to the First World War, his combat service during the Mahdist War and the Boxer Rebellion was all ashore. Appointed Commander-in-Chief of the North America and West Indies Station before the war, his mission was to protect Allied merchant shipping by hunting down German commerce raiders. Late in 1914 he was tasked to search for and destroy the East Asia Squadron of the Imperial German Navy as it headed home around the tip of South America. Believing that he had no choice but to engage the squadron in accordance with his orders, despite his numerical and tactical inferiority, he was killed during the Battle of Coronel off the coast of Chile in November when the German ships sank his flagship.
 Passage 2:During the Russian Revolution of 1905, conflict erupted between the Armenians and the Azeris, culminating in the Armenian-Tatar massacres. In the final year of World War I, Nakhchivan was the scene of more bloodshed between Armenians and Azerbaijanis, who both laid claim to the area. By 1914, the Armenian population was at 40% while the Azeri population increased to roughly 60%. After the February Revolution, the region was under the authority of the Special Transcaucasian Committee of the Russian Provisional Government and subsequently of the short-lived Transcaucasian Democratic Federative Republic. When the TDFR was dissolved in May 1918, Nakhchivan, Nagorno-Karabakh, Zangezur (today the Armenian province of Syunik), and Qazakh were heavily contested between the newly formed and short-lived states of the First Republic of Armenia and the Azerbaijan Democratic Republic (ADR). In June 1918, the region came under Ottoman occupation. Under the terms of the Armistice of Mudros, the Ottomans agreed to pull their troops out of the Transcaucasus to make way for the forthcoming British military presence.
 Passage 3:For the rest of her long career, Ancona served in a variety of roles, both in the main fleet and in Italy's colonial empire. After the end of the war, the government lost confidence in the fleet and drastically reduced the naval budget. The cuts were so severe that the fleet had great difficulty in mobilizing its ironclad squadron to attack the port of Civitavecchia in September 1870, as part of the wars of Italian unification. Instead, the ships were laid up and the sailors conscripted to man them were sent home. Some time after 1866, the ship was rebuilt as a central battery ship, with most of her guns located in a central, armored casemate. Two other guns were placed in the bow as chase guns, with a third mounted as a stern chaser. At around 1871, her armament was also revised, to two guns in the bow and eight 8 in guns, four on each broadside and the last in the stern. Later, her armament was changed again, to eight guns, six guns, four quick firing (QF) guns, and two Hotchkiss revolver cannons. Ancona was stricken from the naval register in 1903 and then broken up for scrap.
