The Battle of Saint-Denis was fought on 10 November 1567 between a Royalist army and Huguenot rebels during the second of the French Wars of Religion. Although their 74 year old commander, Anne de Montmorency, was killed in the fighting, the Royalists forced the rebels to withdraw, allowing them to claim victory. The only major conflict of the second phase, the battle came about when Montmorency attempted to break Condé's siege of Paris. The Huguenot army retreated towards the border, where they linked up with forces led by their ally John Casimir of the Palatinate-Simmern, before besieging Chartres in February 1568. The war ended shortly thereafter.
