In the course of his duties Kościuszko had constantly to make journeys to Warsaw on business. When there he entered into close relations with those noblest of Poland's patriots and reformers, Ignacy Potocki and Hugo Kołłontaj, both holding office under the Crown and employed in drawing up the reforms that the Great Diet was passing. Here too Kościuszko often saw his already friend, Niemcewicz, who was bringing out patriotic plays and taking an active part among the enlightened political party. The high esteem in which Kościuszko was held, not merely by those who loved him personally but by men who only knew of him by repute, may be illustrated by a letter addressed to him, not then, but later, by Kołłontaj, in which the latter tells Kościuszko that words are not needed to express how much he prizes the friendship of one "whom I loved, honoured and admired before fate granted me to know you in person."[2] [Footnote 1: _op. cit_.] [Footnote 2: _Letters of Hugo Kołłontaj_. Poznań, 1872 (Polish).] In 1790 Prussia concluded a defensive and offensive alliance with Poland, which, as the sequel shows, she was prepared to break at the psychological moment, in order to secure Polish help in the probable Prussian war against an Austrian-Russian coalition. Poland began to make ready for the field. Kościuszko was sent southwards, to Lublin, where he remained for the summer months. His employment was to train the recruits for approaching active service. Against the difficulties always to beset him throughout his career of lack of ammunition and want of funds, he devoted himself to his task with the energy and foresight that were customary with him. He was ordered in September to move to Podolia, on the frontiers of which the Russians were massing. He stayed in that district for many months until the July of 1791. There the commandant of Kamieniec was no other than his old comrade and friend, Orłowski. "Truly beloved friend," wrote Orłowski to Kościuszko during the winter of 1790, chaffing him on the untiring activity that he displayed at his post: "I hear from everybody that you don't sit still in any place for a couple of hours, and that you only roam about like a Tartar, not settling anywhere. However, I approve of that. It is evident that you mean to maintain your regiment in the discipline and regularity of military service. I foresee yet another cause for your roaming about the world, which you divulged in my presence. You write to me for a little wife, if I can find one here for you."[1] [Footnote 1: T.
