The Battle of Palestro was fought on 30–31 May 1859 between the Austrian Empire and the combined forces of the Kingdom of Sardinia-Piedmont and France. The Franco-Piedmontese forces were victorious. It was fought just south to Palestro, a town in what is now the province of Pavia in northern Italy. It was believed that the Battle of Palestro was the last European battle in which a European Monarch rode into battle, that being King Victor Emmanuel II, who directly entered the fray with the Austrians.
