Battle of Solferino

The Battle of Solferino (referred to in Italy as the Battle of Solferino and San Martino) on 24 June 1859 resulted in the victory of the allied French Army under Napoleon III and Sardinian Army under Victor Emmanuel II (together known as the Franco-Sardinian Alliance) against the Austrian Army under Emperor Franz Joseph I. It was the last major battle in world history where all the armies were under the personal command of their monarchs. Perhaps 300,000 soldiers fought in this important battle, the largest since the Battle of Leipzig in 1813. There were about 130,000 Austrian troops and a combined total of 140,000 French and allied Piedmontese troops. After this battle, the Austrian Emperor refrained from further direct command of the army.
