As part of
Venetian Albania, Cattaro had belonged to the
Republic of Venice from 1420 to 1797, when it passed to the
Habsburg monarchy with the
Treaty of Campo Formio. In 1805, it was assigned to the
French Empire's client state, the
Napoleonic Kingdom of Italy by the
Treaty of Pressburg, but occupied by Russian troops under
Dmitry Senyavin until they left after the
Treaty of Tilsit in 1807. Three years later it was incorporated into the French Empire's
Illyrian Provinces. Austria declared war on France in August 1813 and by the Autumn the
Royal Navy enjoyed unopposed domination over the Adriatic sea. Working in conjunction with the Austrian armies now invading the Illyrian Provinces and Northern Italy, Rear Admiral
Thomas Fremantle's ships were able to rapidly transport British and Austrian troops from one point to another, forcing the surrender of the strategic ports,
Zara for example
had been liberated in December. Meanwhile, Royal Naval Captain
William Hoste with his ship
HMS Bacchante (38 guns) and a brig-sloop HMS
Saracen (18 guns), under Captain
John Harper had been given orders for the swift expulsion of the French in the region. They took part in an attack that seized the islands of
Hvar and
Brač and moved along the coast. Cattaro was next on the target for the British; a body of Montenegrin troops under
Petar I Petrović-Njegoš a popular spiritual and military leader of the
Serbian Orthodox church from the
Petrović dynasty had surrounded the place.
Saracen arrived first just outside
Cattaro Bay but it was impossible to sail direct to the main fortress so Harper called on the local inhabitants to tow her along the rocky shore for 3 miles. Hoste in
Bacchante arrived soon after with three Sicilian gunboats carrying fifty soldiers and assumed command. The British and Sicilians forced the passage between
Herceg Novi and Fort Rosa and secured an anchorage some three miles inside the outer bay. ==Blockade and siege==
