In the meantime, Sicily proclaimed its independence under the leadership of Ruggero Settimo, who on 13 April 1848 declared the King deposed. In response, the King assembled an army of 20,000 under the command of General Carlo Filangieri and dispatched it to Sicily to subdue the Liberals and restore his authority. A naval flotilla sent to Sicilian waters shelled the city of Messina with "savage barbarity" for eight hours after its defenders had already surrendered, killing many civilians and earning the King the nickname "re bomba" ("King Bomb").
