The Battle of Staffarda, 18 August 1690, was fought during Nine Years' War in Piedmont-Savoy, modern-day northern Italy. The engagement was the first major encounter in the Italian theatre since Victor Amadeus, the Duke of Savoy, had joined the Grand Alliance in opposition to France earlier that year. The battle was a clear victory for the French commander, Nicolas Catinat, who proceeded to take other Piedmontese strongholds. The French also overran most of the Duchy of Savoy, but due to sickness, lack of infantry, and problems with supply, Catinat was unable to besiege Amadeus's capital Turin as King Louis XIV had hoped.
