Bernard René Jourdan, marquis de Launay (1740–1789) was the French governor of the Bastille, the son of a previous governor, and commander of its garrison when it was stormed on 14 July 1789 (see Storming of the Bastille).
The marquis Bernard-René Jordan de Launay was born on the night of 8/9 April 1740 in the Bastille where his father was governor. At the age of eight he was appointed to an honorary position in the King's Musketeers (mousquetaires du roi). He subsequently entered the French Guards (gardes-françaises), a regiment 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 responsibility for the imprisonment of two prime figures in the royal necklace scandal: Cardinal Louis de Rohan and Jeanne de La Motte-Valois. He behaved correctly and considerately with both, although the latter was an extremely difficult inmate.
Until 1777 he was Seigneur of Bretonnière in Normandy. De Launay also owned and rented out a number of houses in the rue Saint-Antoine, neighboring the Bastille.
The permanent garrison of the Bastille, under de Launay, consisted of about 80 invalides (veteran military pensioners) no longer considered suitable for regular army service. Two days before 14 July they were reinforced by thirty Swiss 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. The besiegers interpreted this as treachery on the part of de Launay. The ensuing fighting lasted about four hours, resulting in about 100 casualties among the exposed crowd but only one death and three wounded amongst the well-protected defenders firing from loopholes and battlements. With no source of water and only limited food supplies within the Bastille, de Launay decided to capitulate on the condition that nobody from within the fortress would be harmed. In a note passed out through an opening in the drawbridge he threatened that he would blow up the entire fortress and the surrounding district if these conditions were rejected. De Launay's conditions were rejected but he nevertheless capitulated, reportedly after members of the garrison prevented him from entering the cellars where the gunpowder was stored. At about 5pm firing from the fortress ceased and the drawbridge was suddenly lowered.
