Input: Question: What is the fleet size of the military force that provided assistance to an Austrian force blockade of Zadar in 1813? Passage: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).
