The Battle of Fontenoy, 11 May 1745, was a major engagement of the War of the Austrian Succession, fought between the forces of the Pragmatic Army – comprising mainly Dutch, British, and Hanoverian troops, as well a relatively small contingent of Austrians under the command of the Duke of Cumberland – and a French army under the titular command of King Louis XV of France, with actual field command held by Maurice de Saxe, commander of Louis XV's forces in the Low Countries.
