The siege of Chartres was a key event of the second French Wars of Religion. The siege saw the Huguenot forces fail to take the heavily defended town, ultimately concluding the second civil war in a negotiated settlement a week later. One of the very few engagements in the second civil war, the siege was led by Louis, Prince of Condé, fresh off regrouping after his defeat at the Battle of Saint-Denis. The defensive efforts were run by the military governor of Chartres, Nicolas des Essars, Sieur de Linières.
