The Battle of Bassignana was fought in the Italian campaign of the War of the Austrian Succession on September 27, 1745. It resulted in a victory for the combined armies of France and Spain over Austria and the Kingdom of Sardinia. The Bourbon armies, finally united after a two-year campaign, won through a maneuver that caused 25,000 Austrian troops to head towards Piacenza and leave their Sardinian allies isolated. The Sardinians were then overwhelmed and beaten.
