At Warsaw, the admiral made the acquaintance of, and became the intimate friend of Kosciusko. On the second of November he left Warsaw for Vienna. Here again he was kindly received by those in the highest ranks of society. But in consequence of the sickness of the emperor, he was not favored with an audience. From Warsaw he proceeded to Amsterdam. Kosciusko was at that time deeply engaged in the disastrous conspiracy to liberate Poland from the thraldom of Russia. Sweden was also at war with Russia. There can be no doubt that great efforts were made to enlist the wonderful energies of the admiral, in favor of the two belligerents, against the empress. These efforts were necessarily secret. It is but a glimpse we can get of them. We simply know that the admiral declined all such proffers. From Amsterdam he wrote, under date of December, 1789, to his firm friend President Washington. In that letter he writes: “Count Segur and myself have frequently conversed on subjects that regard America. And the most pleasing reflection of all has been the happy establishment of the new constitution, and that you are so deservedly placed at the head of the government, by the unanimous voice of America. Your name alone, sir, has established in Europe a confidence that was for some time before entirely wanting in American concerns; and I am assured that the happy efforts of your administration are still more sensibly felt throughout the United States. This is more glorious for you than all the laurels that your sword so nobly won in support of the rights of human nature. In war your fame is immortal, as the hero of liberty. In peace you are her patron, and the firmest supporter of her rights. Your greatest admirers and even your best friends have now but one wish left them—that you may long enjoy health and your present happiness.” From Amsterdam he went to Hamburg by way of Copenhagen. Toward the close of April, 1790, he crossed the channel to London. “Upon landing,” he writes, “I escaped being murdered.” After a short visit there he went to Paris. His health was feeble. Still he kept up an active correspondence with his numerous distinguished friends all over the continent. His mode of expressing himself, as the reader will have perceived, was peculiar. He was a man of singular frankness and transparency of character. He gave free utterance to his thoughts as they arose. In Paris he again enjoyed the friendship of Lafayette. Nothing special occurred during his residence in Paris.
