In 1848, Garibaldi returned to Italy and commanded and fought in military campaigns that eventually led to Italian unification. The provisional government of Milan made him a general and the Minister of War promoted him to General of the Roman Republic in 1849. When the war of independence broke out in April 1859, he led his Hunters of the Alps in the capture of major cities in Lombardy, including Varese and Como, and reached the frontier of South Tyrol; the war ended with the acquisition of Lombardy. The following year, he led the Expedition of the Thousand on behalf of and with the consent of Victor Emmanuel II. The expedition was a success and concluded with the annexation of Sicily, Southern Italy, Marche and Umbria to the Kingdom of Sardinia before the creation of a unified Kingdom of Italy on 17 March 1861. His last military campaign took place during the Franco-Prussian War as commander of the Army of the Vosges.
