Battle of Solferino
The Battle of Solferino and San Martino was the largest battle since Leipzig in 1813, with more than 234,000 soldiers fighting for about 12–14 hours and 29,000 victims (14,000 Austrians-Venetians and 15,000 Franco-Sardinians) and about 10,000 prisoners (8,000 Austrians-Venetians and 2,000 Franco-Sardinians). In terms of death toll, it was greater than the Battle of Waterloo.
