The negotiations and conferences of the French plenipotentiaries with the enemy's generals; the proceedings of the Prince of Eckmuhl; the intrigues of the Duke of Otranto; the efforts of those members of the committee, who remained faithful to their trust; the debates on the capitulation of Paris, and all the collateral facts, connected with these different circumstances, had been totally misrepresented; These Memoirs establish or unfold the truth. They bring to light the conduct of those members of the committee, who were supposed to be the dupes or accomplices of Fouché; and that of the marshals, the army, and the chambers. They contain also the correspondence of the plenipotentiaries, and the instructions given to them; documents hitherto unpublished, which will make known, what the politics and wishes of the government of France at that time were.
Finally I shall observe, in order to complete the account I think it right to give the reader of the substance of this work, that it furnishes elucidations of the campaign of 1815, the want of which has been imperiously felt. The causes, that determined Napoleon, to separate from his army at Laon, were not known: I point them out. General Gourgaud, in his narrative, could give no explanation of the march of the corps of Count Erlon at the battle of Ligny, of the conduct of Marshal Ney on the 16th, of the inactivity of Napoleon on the 17th, &c. All these points, I believe, I have elucidated. I show also, that it was not, as General Gourgaud and other writers assert, to raise the spirits, and excite the courage of the French army, that its leader announced to it the arrival of Marshal Grouchy. It is a certain fact, that Napoleon was himself deceived by a brisk firing, which took place between the Prussians and Saxons; and it is falsely, that he has been charged with having knowingly deceived his soldiers, at a moment when the laws of war and of humanity presented to him, to think rather of a retreat, than of continuing the battle.
I had at first rejected from these Memoirs such official papers, as had already been made known: but have since thought, that they ought to be inserted. This work, which embraces all the events of the reign of a Hundred Days, would be imperfect, if the reader were obliged to refer to the papers of the day; to read or consult the act of the congress of Vienna, that placed the Emperor Napoleon out of the pale of the law of nations; the Additional Act, which occasioned his loss of popularity; and the eloquent speeches and nervous declarations by which Napoleon, his ministers, and his counsellors, sought to explain and justify the 20th of March. I have thought, besides, that perhaps the reader would not find it uninteresting, to witness the contests exhibited, at that important period, between the legitimacy of nations and the legitimacy of sovereigns.
