The Siege of Savannah took place early in the fall of 1779, as American and French forces tried to free the city from British control. In early October, the Allied forces launched an assault on key British defensive positions, including the Spring Hill Redoubt. The attack was a failure and the Allies suffered heavy casualties. Soon after, the French abandoned the siege, forcing the Americans do to the same. With the victory, the British retained control of Savannah, and Georgia, until June 1782.
