When Ney and Caulaincourt saw Marmont at Essonnes, he informed them that he had entered into a convention with the Allied sovereigns on his own account. They begged him to suspend it and accompany them, and he consented. Whilst the three commissioners were with the Emperor Alexander, news was brought that Count Souham, with whom Marmont had left the command of his troops, had gone over, and marched the division into the lines of the Allies. On this the Emperor said they had better return to Napoleon, and assure him that the Allies would accept nothing short of an absolute and unqualified abdication. When they announced this to him, to their surprise, he exclaimed, "But what provisions are made for me? How am I to be disposed of?" They replied that it was proposed by the Emperor Alexander that he should retain the title of Emperor; should have the island of Elba, a guard, a small fleet, and all the attributes of royalty, with a suitable income. With a mood of mind incomprehensible in any other person, he immediately called for maps and books about Elba, and began contemplating his future position, as though he had only been changing one France for another; but there can be no doubt that he, in reality, was weighing the facilities of the place for that effort to regain the empire of France, which he certainly never renounced for a moment. On the 11th of April he drew up a form of unconditional abdication, signed, and dispatched it. Ney, Macdonald, and Caulaincourt arrived with the treaty to which the Allied sovereigns had agreed. Elba was assigned to him--an island twenty leagues in extent, with twelve thousand inhabitants--and he was to have an income of six millions of francs, besides the little revenue of the island. Two millions and a half more were assigned as annuities to Josephine, and the other members of his family. The Empress was to be created Duchess of Parma, Placentia, and Guastella, in full sovereignty. The marshals and other officers of his army were received into the same ranks and dignities in the army of the Bourbon sovereign. Lord Castlereagh, who had arrived after the conclusion of this treaty, pointed out the folly of it, which must have been apparent to every man of the slightest reflection; for, to a certainty, Napoleon would not for a day longer than he was compelled observe it in a place like Elba, in the very vicinity of France. He declined, on the part of Great Britain, any concern in it; but to avoid a renewal of the war, he offered no formal opposition. Napoleon arrived at Elba on the 4th of May.
