Siege of Chartres (1568)
The Siege of Chartres in February to March 1568 was the pivotal event which ended the Second War of Religion, an episode of the French Wars of Religion.
The Huguenot army besieged the town at the end of February. The Prince of Condé had five battering cannons and four light culverins. Part of the army acted as block and the rest, about 9,000 men, encircled the town and used their nine guns to breach the north wall. The Huguenots assaulted the town on 7 March but the Royal garrison of Nicolas des Essars, assisted by inhabitants defended stoutly. The assault was repelled and the breach sealed off.
Following the lifted siege, the Peace of Longjumeau was signed, on 23 March.
