In 1848 Venice rebelled, declaring independence from the Austrian Empire. Vulcano and other Austrian vessels managed to escape capture, however most of their men deserted to the Venetian side, in many cases since non-Italian officers promised immediate discharges to their Italian sailors. In March 1848 Vulcano evacuated the personnel of the Austrian embassy from Naples, but the crew mutinied mid-route and attempted to direct the ship to Venice, however the ambassador Prince Felix of Schwarzenberg managed to restore order and direct the ship to Trieste. Vulcano was part of squadron commanded by Captain Ludwig Kudriaffsky that blockaded Venice in April 1848. On 26 April 1848 the Vulcano intercepted a Greek brig attempting to break the blockade, but was engaged in a gun battle with the Venetian Pio Nono who hit the Vulcano twice forcing her to withdraw.
Balloon bombardment
In July 1849 Vulcano took part in the first aggressive use of balloons in warfare, serving as a balloon carrier in the first offensive use of air power in naval aviation. Austrian forces besieging Venice attempted to float some 200 paper hot air balloons, each carrying a 24- to 30-pound bomb that was to be dropped from the balloon with a time fuse over the besieged city. The balloons were launched mainly from land; however, some were also launched from Vulcano. The Austrians used smaller pilot balloons to determine the correct fuse settings. At least one bomb fell in the city; however, due to the wind changing after launch, most of the balloons missed their target, and some drifted back over Austrian lines and the launching ship Vulcano. On 4 July, she had run aground at Malamocco and come under fire from Manfrin Fort. A crew member was killed. She was damaged at her paddlebox. Vulcan was refloated the next day with assistance from and the Austrian steamships Curtatone and Dorotea.
On 17 November 1869, was one of seventy ships, all of which drew less than 13 feet of water, that sailed through the Suez Canal in a procession marking the opening of the canal. Remained in service until 1872, and finally struck in 1884 to become a coal hulk.
