The plenipotentiaries of Napoleon had been directed to confer with Marmont at Essonne, in their road to the capital. They did so, and obtained information there, which rendered their negotiation more pressing. Several of the generals who had not been at Fontainbleau, and had not had an opportunity of acting in conjunction with the military council which assembled there, had viewed the act of the Senate, adhered to by the other public bodies, as decisively closing the reign of Buonaparte, or as indicating the commencement of a civil war. Most of them were of opinion, that the interest of an individual, whose talents had been as dangerous to France as the virtues of Cæsar had been to Rome, ought not to be weighed against the welfare of the capital and the whole nation. Victor, Duke of Belluno, had upon these principles given in his personal adhesion to the Provisional Government, and his example was followed by many others.
But the most important proselyte to the royal cause was the Maréchal Marmont, Duke of Ragusa, who, lying at Essonne with ten or twelve thousand men, formed the advance of the French army. Conceiving himself to have the liberty of other Frenchmen to attend at this crisis to the weal of France, rather than to the interest of Napoleon alone, and with the purpose of saving France from the joint evils of a civil and domestic war, he made use of the position in which he was placed, to give a weight to his opinion, which that of no other individual could have possessed at the moment. Maréchal Marmont, after negotiation with the Provisional Government on the one hand, and Prince Schwartzenberg on the other, had entered into a convention on his own account, and that of his corps d'armée, by which he agreed to march the division which he commanded within the lines of cantonment held by the allies, and thus renounced all idea of further prosecuting the war. On the other hand, the maréchal stipulated for the freedom and honourable usage of Napoleon's person, should he fall into the hands of the allies. He obtained also a guarantee, that his corps d'armée should be permitted to retreat into Normandy. This convention was signed at Chevilly, upon 3d April.[42]
