A career soldier who commanded in the West Indies during the American war, taking Dominica and Tobago, Bouillé sat in the Assembly of Notables and by 1790 held command in Alsace, Lorraine and Franche-Comté. In August 1790 he suppressed the mutiny of the Nancy garrison by force; the courts-martial that followed sentenced large numbers of the Swiss Châteauvieux regiment to death or the galleys, and the survivors were later fêted in Paris as victims. With Fersen and Breteuil he planned the royal family’s escape to Montmédy in June 1791, posting cavalry relays along the route, none of which intervened. He then crossed the frontier and wrote to the Assembly claiming sole responsibility and threatening Paris with foreign reprisal. He died in London in November 1800.
