The first major voyage took the San Michele to Brazil in 1842 . In 1847 she brought cannons acquired in Sweden to Genoa. In 1848, the San Michele in the Adriatic took part in the first Italian War of Independence , in particular in protecting the Repubblica di San Marco in Venice , and then in the fruitless blockade of Trieste , where it was damaged. In 1856 she supported a Piedmontese troop contingent in the Crimea as part of a larger naval unit in the Black Sea during the Crimean War . In September 1860 it supported the Piedmontese troops on the Adriatic coast in their operations near Castelfidardo and Ancona , then in the fighting for Gaeta , where it was damaged again.
After the unification of Italy, the now outdated San Michele was used as a sailing training ship until 1868 and then sold for scrapping in March 1875.
