Since my return to France I had heard much of the intrigues of M. Czernischeff, an aide de camp of the Emperor of Russia, who, under the pretest of being frequently sent to compliment Napoleon on the part of the Emperor Alexander, performed, in fact, the office of a spy. The conduct of Napoleon with regard to M. Czernischeff at that period struck me as singular, especially after the intelligence which before my departure from Hamburg I had transmitted to him respecting the dissatisfaction of Russia and her hostile inclinations. It is therefore clear to me that Bonaparte was well aware of the real object of M. Czernischeffs mission, and that if he appeared to give credit to the increasing professions of his friendship it was only because he still wished, as he formerly did; that Russia might so far commit herself as to afford him a fair pretext for the commencement, of hostilities in the north.
M. Czernischeff first arrived in Paris shortly after the interview at Erfurt, and after that period was almost constantly on the road between Paris and St. Petersburg; it has been computed that in the space of less than four years he travelled more than 10,000 leagues. For a long time his frequent journeyings excited no surmises, but while I was in Paris Savary began to entertain suspicions, the correctness of which it was not difficult to ascertain, so formidable was still the system of espionage, notwithstanding the precaution taken by Fouche to conceal from his successor the names of his most efficient spies. It was known that M. Czernischeff was looking out for a professor of mathematics,—doubtless to disguise the real motives for his stay in Paris by veiling them under the desire of studying the sciences. The confidant of Alexander had applied to a professor connected with a public office; and from that time all the steps of M. Czermseheff were known to the police. It was discovered that he was less anxious to question his instructor respecting the equations of a degree, or the value of unknown quantities, than to gain all the information he could about the different branches of the administration, and particularly the department of war. It happened that the professor knew some individuals employed in the public offices, who furnished him with intelligence, which he in turn communicated to M. Czernischeff, but not without making a report of it to the police; according to custom, instead of putting an end to this intrigue at once it was suffered fully to develop itself. Napoleon was informed of what was going on, and in this instance gave a new proof of his being an adept in the art
