In his Proclamation of 1860, Garibaldi demanded that Italy helped Sicilians fight against the "enemies of Italy, and for Italy." In his opinion. Sicilians fighting for the land of Italy should be an example and calling for the Italians to join the war and help them, for it is a fight for the Motherland- Italy.
