During the Armagnac–Burgundian Civil War, Paris surrendered to Jean de Villiers de L'Isle-Adam, captain of a troop of supporters of the Duke of Burgundy. Tanneguy succeeded in removing the Dauphin who was amidst his enemies and protected him by welcoming him to the Bastille. On 29 May 1418, the Dauphin left the Bastille to take refuge in Bourges with loyalists.
