CHAPTER XIII. _The Mission to Denmark._ Letter to Mr. Jefferson.—The Marquise de Marsan.—Unfounded Charges and Vindication.—Flattering Application from Catherine II.—His Reception at the Polish Court.—Jones receives the Title of Rear-Admiral.—English Insolence.—Letter of Catherine II. Just before Mr. Jones left Europe, he transmitted a letter to Congress, informing them that the piratic regency of Algiers had armed eight war vessels, carrying from eighteen to thirty-four guns each, which were to cruise between Cape St. Vincent and the Azores, to capture American ships. The French minister, M. Soulanges, at Toulon, had ascertained this fact, and very kindly, immediately communicated it to Mr. Jones. In writing to Mr. Jefferson upon the subject, the commodore said: “This event may, I believe, surprise some of our fellow-citizens. But, for my part, I am rather surprised that it did not take place sooner. It will produce a good effect, if it unites the people of America in measures consistent with their national honor and interest, and rouses them from that ill-judged security, which the intoxication of success has produced since the revolution.” One of his most valued lady friends in France, a daughter of Louis XV., wrote to him, in deepest affliction. Though a daughter of the king, and as such enjoying high rank, she was not regarded as a member of the royal family. The king bestowed a large fortune upon the mother, on the daughter’s account. The father died when the daughter, who was a great favorite of his, was very young. The mother then greatly neglected this child of a royal sire, treating her neither with natural affection nor justice. This young lady was adopted by the Marquise de Marsan, who became to her as a mother, and introduced her to the highest society of the court. She was very happily married to M. Tellison, a very worthy gentleman, but without fortune. In this virtuous family, Commodore Jones had found, in his lonely hours in Paris, a congenial and happy home. The aged marquise regarded the young hero as her own son. Monsieur and Madame Tellison treated him with truly fraternal affection. Their little boy was a great favorite of the commodore, as he fondled him upon his knee, and lavished caresses upon him. Man is born to mourn. The day of sorrow came to this united and happy family. On the 23d of June, 1787, Madame Tellison wrote to Paul Jones, in New York, informing him of the sudden death of her friend and protectress, the Marquise de Marsan, and of consequently a great reverse in their pecuniary condition. Jones, writing to Dr. Bancroft in London, alluding to this event, said: “This is also a great grief and loss to me, as I had in that lady a valuable friend.” The letter Madame Tellison had written to Mr. Jones, was forwarded to him by Thomas Jefferson. He immediately wrote to Mr. Jefferson as follows:
