The Battle of Villafranca unfolded on 20 April 1744, during the War of the Austrian Succession. The armies of Spain and France, advancing into Kingdom of Sardinia, unsuccessfully attacked entrenched positions at the pass of Villafranca, defended by Anglo-Sardinian forces. Because of the high losses incurred, the defenders were forced to leave the harbour of Villafranca two days after the battle (22 April 1744).
