The Battle of Gavinana was a battle in the War of the League of Cognac. It was fought on 3 August 1530 between the city of Florence and the Imperial army of the Holy Roman Empire. The Imperial forces were led by Philibert of Châlon, Prince of Orange, with reinforcements under Fabrizio Maramaldo arriving later in the battle. The Florentine forces were led by the florentine commissary Francesco Ferruccio. At first the Florentines drove back the Imperial army, despite being outnumbered. In the process, the Prince of Orange was fatally shot in the chest by two arquebus balls.
