Louis Joseph established himself at Coblenz in 1791, where he helped to organize and lead a large counter-revolutionary army of émigrés. In addition to containing the prince's grandson, Louis-Antoine-Henri de Bourbon-Condé, duc d'Enghien, and the two sons of his cousin, the late king's brother, the comte d'Artois, the corps included many young aristocrats who eventually became leaders during the Bourbon Restoration years later. This group also included Armand-Emmanuel du Plessis, Duc de Richelieu, Pierre Louis Jean Casimir de Blacas and François-René de Chateaubriand.
