When, on a former occasion, I spoke of the Duke of, Mecklenburg-Schwerin and his family, I forgot a circumstance respecting my intercourse with him which now occurs to my memory. When, on his expulsion from his States, after the battle of Jena, he took refuge in Altona, he requested, through the medium of his Minister at Hamburg, Count von Plessen, that I would give him permission occasionally to visit that city. This permission I granted without hesitation; but the Duke observed no precaution in his visits, and I made some friendly observations to him on the subject. I knew the object of his visits. It was a secret connection in Hamburg; but in consequence of my observations he removed the lady to Altona, and assured me that he adopted that determination to avoid committing me. He afterwards came very seldom to Hamburg; but as we were on the best understanding with Denmark I frequently saw his daughter, and son-in-law, who used to visit me at a house I had in Holstein, near Altona.
There I likewise saw, almost every day, the Duke of Weimar, an excellent old man. I had the advantage of being on such terms of intimacy with him that my house was in some measure his. He also had lost his States. I was so happy as to contribute to their restitution, for my situation enabled me to exercise some influence on the political indulgences or severities of the Government. I entertained a sincere regard for the Duke of Weimar, and I greatly regretted his departure. No sooner had he arrived in Berlin than he wrote me a letter of, thanks, to which he added the present of a diamond, in token of his grateful remembrance of me. The Duke of Mecklenburg was not so fortunate as the Duke of Weimar, in spite of his alliance with the reigning family of Denmark. He was obliged to remain at Altona until the July following, for his States were restored only by the Treaty of Tilsit. As soon as it was known that the Emperor had returns to Paris the Duke's son, the Hereditary Prince, visited me in Hamburg, and asked me whether I thought he could present himself to the Emperor, for the purpose of expressing his own and his father's gratitude. He was a very well-educated young man. He set out, accompanied by M. Oertzen and Baron von Brandstaten. Some time afterwards I saw his name in the Moniteur, in one of the lists of presentations to Napoleon, the collection of which, during the Empire, might be regarded as a general register of the nobility of Europe.
It is commonly said that we may accustom ourselves to anything, but to me this remark is subject to an exception; for, in spite of the necessity to which I was reduced of employing spies, I never could surmount the disgust I felt at them, especially when I saw men destined to fill a respectable rank in society degrade themselves to that infamous profession. It is impossible to conceive the artifices to which these men resort to gain the confidence of those whom they wish to betray. Of this the following example just now occurs to my mind.
One of those wretches who are employed in certain circumstances, and by all parties, came to offer his services to me. His name was Butler, and he had been sent from England to the Continent as a spy upon the French Government. He immediately came to me, complaining of pretended enemies and unjust treatment. He told me he had the greatest wish to serve the Emperor, and that he would make any sacrifice to prove his fidelity. The real motive of his change of party was, as it is with all such men, merely the hope of a higher reward. Most extraordinary were the schemes he adopted to prevent his old employers from suspecting that he was serving new ones. To me he continually repeated how happy he was to be revenged on his enemies in London. He asked me to allow him to go to Paris to be examined by the Minister of Police. The better to keep up the deception he requested that on his arrival in Paris he might be confined in the Temple, and that there might be inserted in the French journals an announcement in the following terms:
"John Butler, commonly called Count Butler, has just been arrested and sent to Paris under a good escort by the French Minister at Hamburg."
At the expiration of a few weeks Butler, having received his instruction's, set out for London, but by way of precaution he said it would be well to publish in the journals another announcement; which was as follows:
"John Butler, who has been arrested in Hamburg as an English agent,
and conveyed to Paris, is ordered to quit France and the territories
occupied by the French armies and their allies, and not to appear
there again until the general peace."
In England Butler enjoyed the honours of French prosecution. He was regarded as a victim who deserved all the confidence of the enemies of France. He furnished Fouche with a considerable amount of information, and he was fortunate enough to escape being hanged.
Notwithstanding the pretended necessity of employing secret agents, Bonaparte was unwilling that, even under that pretext, too many communications should be established between France and England: Fouche, nevertheless, actively directed the evolutions of his secret army. Ever ready to seize on anything that could give importance to the police and encourage the suspicions of the Emperor, Fouche wrote to me that the government had received certain—information that many Frenchmen traveling for commercial houses in France were at Manchester purchasing articles of English manufacture. This was true; but how was it to be prevented? These traveling clerks passed through Holland, where they easily procured a passage to England.
Louis Bonaparte, conceiving that the King of Holland ought to sacrifice the interests of his new subjects to the wishes of his brother, was at first very lenient as to the disastrous Continental system. But at this Napoleon soon manifested his displeasure, and about the end of the year 1806 Louis was reduced to the necessity of ordering the strict observance of the blockade. The facility with which the travelers of French commercial houses passed from Holland to England gave rise to other alarms on the part of the French Government. It was said that since Frenchmen could so easily pass from the Continent to Great Britain, the agents of the English Cabinet might, by the same means, find their way to the Continent. Accordingly the consuls were directed to keep a watchful eye, not only upon individuals who evidently came from England, but upon those who might by any possibility come from that country. This plan was all very well, but how was it to be put into execution ? . . . The Continent was, nevertheless, inundated with articles of English manufacture, for this simple reason, that, however powerful may be the will of a sovereign, it is still less powerful and less lasting than the wants of a people. The Continental system reminded me of the law created by an ancient legislator, who, for a crime which he conceived could not possibly be committed, condemned the person who should be guilty of it to throw a bull over Mount Taurus.
