Question: What is the fleet size of the military force that provided assistance to an Austrian force blockade of Zadar in 1813? Passage 1:In 1797 with the Treaty of Campo Formio, the Republic of Venice, including Zadar, came under the Austrian crown. In 1806 it was briefly given to the Napoleonic Kingdom of Italy, until in 1809 it was added to the French Illyrian Provinces. In November 1813 an Austrian force blockaded the town with the assistance of two British Royal Navy frigates HMS Havannah and Weazle under the 3rd Earl of Cadogan. On 9 December the French garrison of Zadar capitulated, and by the end of the year all of Dalmatia was brought back under the control of the Austrian Empire. After the Congress of Vienna (1815) until 1918, the town (bilingual name Zara Zadar ) remained part of the Austrian monarchy (Austria side after the compromise of 1867), head of the district of the same name, one of the 13 Bezirkshauptmannschaften in Dalmatia. The Italian name was officially used before 1867. It remained also the capital of Dalmatia province (Kronland).
Passage 2:Michael Mitnick began writing the script for The Current War in 2008, basing it on the real life "war of the currents" AC/DC conflict between Edison and Westinghouse. The screenplay is the conclusive result of sixty drafts, a ten-year writing process, first as a musical and finally as a film. In 2011 Mitnick's screenplay made the Black List, an industry survey of "most liked" screenplays not yet produced. On May 3, 2012, it was reported that Timur Bekmambetov's company, Bazelevs, had acquired the rights to Mitnick's screenplay. Bekmambetov was set to direct. On March 31, 2014, it was reported that Ben Stiller was in negotiations to direct the film. As of September 24, 2015, Benedict Cumberbatch and Jake Gyllenhaal were in talks to play Thomas Edison and George Westinghouse, respectively, with Alfonso Gomez-Rejon (Me and Earl and the Dying Girl) eyed to direct the film. Sacha Baron Cohen was also briefly linked to the role of Edison. On September 29, 2016, Michael Shannon was cast as Westinghouse, and on October 4, Nicholas Hoult was cast as Nikola Tesla. In November 2016, Katherine Waterston and Tom Holland joined the cast. The following month, Tuppence Middleton and Matthew Macfadyen were cast.
Passage 3:The main reasons for Cleveland's return into politics were his desire to prevent New York Governor David B. Hill (a political rival of Cleveland's who also wanted the 1892 Democratic nomination) from winning the Democratic Presidential nomination that year and Cleveland's staunch opposition to free silver, a prominent political issue back then. Cleveland considered Governor Hill to be a corrupt machine boss, and he staunchly believed that the Democrats should maintain their support of the gold standard. Cleveland hired former U.S. Navy Secretary William C. Whitney as his campaign manager that year. Cleveland and Whitney frequently contacted Southern politicians and newspaper editors in an attempt to get them to support Cleveland's 1892 Presidential bid. Cleveland portrayed himself as a candidate who can unify the Democratic Party (due to his status as a former President and the only Democrat elected U.S. President since the U.S. Civil War) and tried appealing to Southerners by opposing federal oversight of African American voting rights. Whitney also fundraised huge amounts of cash from wealthy bankers and businessmen in order to finance Cleveland's Presidential campaign. An attempt by New York Democratic Party chairman Edward Murphy to strengthen Governor Hill's chances for the 1892 Democratic nomination by giving him all of New York's delegates backfired and ended up helping Cleveland (since most of the delegates from the other states ended up supporting him afterwards). When the 1892 Democratic National Convention convened on June 21, 1892, in Chicago, Cleveland was narrowly able to win the Democratic party nomination for U.S. President on the first ballot.
