The Battle of Solferino on 24 June 1859 resulted in the victory of the allied French army under Napoleon III and the Piedmont-Sardinian army under Victor Emmanuel II 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. There were approximately 300,000 soldiers on both sides in the most important battle, the largest since the Battle of Leipzig in 1813. The number of soldiers present was about 130,000 Austrian troops and a combined total of 140,000 French and allied Piedmontese troops, but not all were actually involved in the battle. After the battle, the Austrian emperor stopped directly commanding the army.
