Concurrent with the resolve of the marshals at Fontainebleau ran the actual treason of one who alone was more important to Napoleon's cause than all of them. "I am ready to leave, with my troops, the army of the Emperor Napoleon on the following conditions, of which I demand from you a written guaranty," are the startling words from a letter of Marmont to the Czar, dated the previous day. On April first agents of the provisional government had made arrangements with a discredited nobleman named Maubreuil for the assassination of Napoleon; the next day Schwarzenberg introduced into the French lines newspapers and copies of a proclamation explaining that the action of the senate and of all France had released the soldiers from their oaths. Marmont forwarded the documents he received to Berthier, and while most of the officers flung their copies away in contemptuous scorn, some read and pondered. On April third an emissary from Schwarzenberg appeared at Marmont's headquarters, and what he said was spoken to willing ears. Still under the influence of the homage he had received in Paris, the vain marshal saw himself repeating the role of Monk; he beheld France at peace, prosperity restored, social order reestablished, and himself extolled as a true patriot--all this if only he pursued the easy line of self-interest, whereby he would not merely retain his duchy, but also secure the new honors and emoluments which would be showered on him. So he yielded on condition that his troops should withdraw honorably into Normandy, and that Napoleon should be allowed to enjoy life and liberty within circumscribed limits fixed by the allied powers and France. Next morning, the fourth, came Schwarzenberg's assent, and Marmont at once set about suborning his officers; at four in the afternoon arrived an embassy from Fontainebleau on its way to Paris. The officers composing it desired to see Marmont.
