The Battle of Custoza took place on June 24, 1866 during the Third Italian War of Independence in the Italian unification process.

The Austrian Imperial army, joined by the Venetian Army, jointly commanded by Archduke Albrecht of Habsburg, defeated the Italian army, led by Alfonso Ferrero la Marmora and Enrico Cialdini, despite the Italians' strong numerical advantage.


In June 1866, the German Kingdom of Prussia declared war on the Austrian Empire. The recently formed Kingdom of Italy decided to seize the opportunity and allied with Prussia with the intention of annexing Venetia and thus uniting the Italian Peninsula. The Italians rapidly built up a military force that was twice the size of their Austrian counterparts defending Venetia.
