Battle of Solferino
The Austrian invasion was stopped by the arrival of French troops in Piedmont that had begun in late April. The Austrians were defeated at the Battle of Magenta on 4 June and pushed back to Lombardy, where the Franco-Sardinian victory at the Battle of Solferino on 24 June resulted in the end of the war and the signing of the Armistice of Villafranca on 12 July.
