Bernard-René Jourdan de Launay permanently stationed in Paris except in time of war. In 1776 de Launay succeeded M. de Jumilhac as Governor of the Bastille. As was the custom with many senior positions under the Ancien Régime, the marquis purchased the office of governor from his predecessor as a form of investment. The thirteen years that he spent in this position were uneventful, though on 19 December 1778 he reportedly made the mistake of failing to fire the cannon of the Bastille as a salute on the birth of a daughter (Madame Royale) to King Louis XVI. In August 1785 he was given
Bernard-René Jourdan de Launay grenadiers from the Salis-Samade Regiment. Unlike Sombreuil, the governor of Hôtel des Invalides, who had accepted the revolutionaries' demands earlier that day, de Launay refused to surrender the prison fortress and hand over the arms and the gunpowder stored in the cellars. He promised that he would not fire unless attacked and tried to negotiate with two delegates from the Hôtel de Ville, but the discussions drew out. A part of the impatient crowd started to enter the outer courtyard of the fortress after a small group broke the chains securing the drawbridge. After shouting warnings the garrison opened fire.
