An ill-fated French Royalist, born at Chantilly; joined the Royalists under his grandfather, Prince of Condé, and took part in the Rhine campaign against the Republicans; was suspected of being concerned in a Bourbon plot to assassinate the Emperor Napoleon; was seized in the neutral territory of Baden, brought to Vincennes, and, after an inconclusive and illegal trial, shot by Napoleon's orders, a proceeding which gave rise to Fouché's remark, "It is worse than a crime—it is a blunder" (1772-1804).
