He had secured powerful aid to carry out his plan. The Bourbon princes supported him, and one of them was to land on the north coast and put himself at the head of the royalist sympathizers as soon as the First Consul was killed. In this plot was associated Pichegru, who had been connected with the 18th Fructidor. General Moreau, the hero of Hohenlinden, was suspected of knowing something of it. It came to light in time, and a general arrest was made of those suspected of being privy to it. The first to be tried and punished was the Duc d’Enghien, who had been seized at Ettenheim, in Baden, a short distance from the French frontier, on the supposition that he had been coming secretly to Paris to be present at the meetings of the conspirators. His trial at Vincennes was short, his execution immediate. There is good reason to believe that Napoleon had no suspicion that the Duc d’Enghien would be executed so soon as he was, and even to suppose that he would have lightened the sentence if the punishment had not been pushed on with an irregularity and inhumanity that recalls the days of the Terror. The execution was a severe blow to Napoleon’s popularity, both at home and abroad. Fouché’s cynical remark was just: “The death of the Duc d’Enghien is worse than a crime; it is a blunder.” Chateaubriand, who had accepted a foreign embassy, resigned at once, and a number of the old aristocracy, such as Pasquier and Molé, who had been saying among themselves that it was their duty to support Napoleon’s splendid work of reorganization, went back into obscurity. In society the effect was distressing. The members of Napoleon’s own household met him with averted faces and sad countenances, and Josephine wept until he called her a child who understood nothing of politics. Abroad there was a revulsion of sympathy, particularly in the cabinets of Russia, Prussia, and Austria. The trial of Cadoudal and Moreau followed. The former with several of his accomplices was executed. Moreau was exiled for two years. Pichegru committed suicide in the Temple.
