The Battle of Castelfidardo was a battle that took place on 18 September 1860, at Castelfidardo, a small town in the Marche region of Italy. It was fought between the Sardinian army - acting as the driving force in the war for Italian unification, against the Papal States.[1]

On 7 September, Cavour, Prime Minister of Piedmont, sent an ultimatum to the Pope demanding that he dismiss his foreign troops. When he failed to do this, 35,000 troops crossed the border on 11 September, with General Cialdini advancing along the Adriatic coast and General Della Rocca leading another troop across Umbria. The Papal troops were caught by surprise and thrown into confusion. Some of the Papal troops surrendered the same day and some retreated to Ancona which fell on 29 September 1860 after a short siege.[1]

As a result of this battle, the Marches and Umbria entered in the Kingdom of Italy and the extent of the Papal States was reduced to the area of what is today known as Lazio.[1]

The battle is remembered for being bloody, and for the highly disparate numbers of troops - less than 10,000 papal soldiers to 39,000 Sardinians. The papal army was composed of volunteers from many different European countries, amongst whom the French and Belgian nationals constituted a Franco-Belgian battalion. Among the French volunteers were a notable number of nobles from western France: after the battle, whilst consulting the list of dead and wounded members of the papal army, the Sardinian general Cialdini is reported to have said, in an example of rather black humor, "you would think this was a list of invites for a ball given by Louis XIV!"[2]


The Franco-Belgian, Austrian and Irish battalions later joined the Papal Zouave corps, an infantry regiment of international composition that pledged to aid Pope Pius IX in the protection of the Papacy for the remainder of the Italian unificationist Risorgimento.

The battle was commemorated by the Italian ironclad Castelfidardo, built in the 1860s.
