A gigantic conspiracy was formed in England by Count d'Artois, subsequently Charles X., and other French emigrants, for the assassination of Napoleon. The plan was for a hundred resolute men, led by the desperate George Cadoudal, to waylay Napoleon when passing, as was his wont, with merely a small guard of ten outriders, from the Tuileries to Malmaison. The conspirators flattered themselves that this would be considered war, not assassination. The Bourbons were then to raise their banner in France, and the emigrants, lingering upon the frontiers, were to rush into the empire with the Allied armies, and re-establish the throne of the old regime. The Princes of Conde grandfather, son, and grandson, were then in the service and pay of Great Britain, fighting against their native land, and, by the laws of France traitors, exposed to the penalty of death. The grandson, the Duke d'Enghien, was on the French frontier, in the duchy of Baden, waiting for the signal to enter France arms in hand. It was supposed that he was actively engaged in the conspiracy for the assassination, as he was known frequently to enter France by night and in disguise. But it afterward appeared that these journeys were to visit a young lady to whom the duke was much attached. Napoleon, supposing that the duke was involved in the conspiracy, and indignant in view of these repeated plots, in which the Bourbons seemed to regard him but as a wild beast whom they could shoot down at their pleasure, resolved to teach them that he was not thus to be assailed with impunity. A detachment of soldiers was sent across the border, who arrested the duke in his bed, brought him to Vincennes, where he was tried by court-martial, condemned as a traitor waging war against his native country, and, by a series of accidents, was shot before Napoleon had time to extend that pardon which he intended to grant. The friends of Napoleon do not severely censure him for this deed. His enemies call it wanton murder. Joseph thus speaks of this event: [Illustration: JOSEPH AT MALMAISON.] "The catastrophe of the Duke d'Enghien requires of me some details too honorable to the memory of Napoleon for me to pass them by in silence. Upon the arrival of the duke at Vincennes, I was in my home at Mortfontaine. I was sent for to Malmaison. Scarcely had I arrived at the gate when Josephine came to meet me, very much agitated, to announce the event of the day. Napoleon had consulted Cambaceres and Berthier, who were in favor of the prisoner; but she greatly feared the influence of Talleyrand, who had already made the tour of the park with Napoleon. "'Your brother,' said she, 'has called for you several times. Hasten to interrupt this long interview; that lame man makes me tremble.'
