I had scarcely left Hamburg when the Prince of Eckmuhl (Marshal Davoust) was appointed Governor-General of that place on the union of the Hanse Towns with the Empire. From that period I was constantly occupied in contending against the persecutions and denunciations which he racked his imagination to invent. I cannot help attributing to those persecutions the Emperor's coolness towards me on my arrival in Paris. But as Davoust's calumnies were devoid of proof, he resorted to a scheme by which a certain appearance of probability might supply the place of truth. When I arrived in Paris, at the commencement of 1811, I was informed by an excellent friend I had left at Hamburg, M. Bouvier, an emigrant, and one of the hostages of Louis XVI., that in a few days I would receive a letter which would commit me, and likewise M. de Talleyrand and General Rapp. I had never had any connection on matters of business, with either of these individuals, for whom I entertained the most sincere attachment. They, like myself, were not in the good graces of Marshal Davoust, who could not pardon the one for his incontestable superiority of talent, and the other for his blunt honesty. On the receipt of M. Bouvier's letter I carried it to the Due de Rovigo, whose situation made him perfectly aware of the intrigues which had been carried on against me since I had left Hamburg by one whose ambition aspired to the Viceroyalty of Poland. On that, as on many other similar occasions, the Duc de Rovigo advocated my cause with Napoleon. We agreed that it would be best to await the arrival of the letter which M. Bouvier had announced. Three weeks elapsed, and the letter did not appear. The Duc de Rovigo, therefore, told me that I must have been misinformed.
However, I was certain that M. Bouvier would not have sent me the information on slight grounds, and I therefore supposed that the project had only been delayed. I was not wrong in my conjecture, for at length the letter arrived. To what a depth of infamy men can descend! The. letter was from a man whom I had known at Hamburg, whom I had obliged, whom I had employed as a spy. His epistle was a miracle of impudence.
After relating some extraordinary transactions which he said had taken place between us, and which all bore the stamp of falsehood, he requested me to send him by return of post the sum of 60,000 francs on account of what I had promised him for some business he executed in England by the direction of M. de Talleyrand, General Rapp, and myself. Such miserable wretches are often caught in the snares they spread for others. This was the case in the present instance, for the fellow had committed, the blunder of fixing upon the year 1802 as the period of this pretended business in England, that is to say, two years before my appointment as Minister-Plenipotentiary to the Hanse Towns. This anachronism was not the only one I discovered in the letter.
I took a copy of the letter, and immediately carried the original to the Duc de Rovigo, as had been agreed between us. When I waited on the Minister he was just preparing to go to the Emperor. He took with him the letter which I brought, and also the letter which announced its arrival. As the Duc de Rovigo entered the audience-chamber Napoleon advanced to meet him, and apostrophised him thus: "Well, I have learned fine things of your Bourrienne, whom you are always defending." The fact was, the Emperor had already received a copy of the letter, which had been opened at the Hamburg post-office. The Due de Rovigo told the Emperor that he had long known what his Majesty had communicated to him.
He then entered into a full explanation of the intrigue, of which it was wished to render me the victim, and proved to him the more easily the falsehood of my accusers by reminding him that in 1802 I was not in Hamburg, but was still in his service at home.
It may be supposed that I was too much interested in knowing what had passed at the Tuileries not to return to the Duc de Rovigo the same day.
