The West Point episode of Kościuszko's career came to its end in the summer of 1780, when he asked Washington to transfer him to the southern army. The motive of the request was that, without having given Kościuszko notice, Washington had removed a number of his workmen. The correspondence that passed between them was courteous but dry, Kościuszko avoiding acrimonious expressions, and simply stating that under the present conditions he could no longer carry on the work at West Point. The relations between the liberator of America and the champion of Poland's freedom were, indeed, never of the nature exacted by romance. They were confined to strict necessity, and held none of the affection that marked the intercourse of Gates and Nathaniel Greene with their Polish engineer. The precise reason of this is hard to fathom. It has been ascribed to Kościuszko's intimacy with Gates, Washington's adversary, or, again, to Kościuszko's extreme reserve--which latter conjecture, in view of the warm and enduring friendships that the hero of Poland won for himself in the New World, seems untenable. Gates, now nominated to the command of the southern army, had at once requested that Kościuszko should be sent to him. "The perfect qualities of that Pole," he wrote to Jefferson, "are now properly appreciated at headquarters, and may incline other personages to putting obstacles against his joining us; but if he has once promised we can depend upon him." Washington gave the required permission, to which Kościuszko replied from West Point on August 4th: "The choice your Excellency was pleased to give me in your letter of yesterday is very kind; and, as the completion of the works at this place during this campaign, as circumstances are, will be impossible in my opinion, I prefer going to the southward to continuing here. I beg you to favour me with your orders, and a letter of recommendation to the Board of War, as I shall pass through Philadelphia. I shall wait on your Excellency to pay due respects in a few days."[1] A French engineer took Kościuszko's place, and the latter had not long left when the treachery of the new commandant of West Point, Arnold, was disclosed by the capture of André. Before Kościuszko had time to reach the southern army his old friend Gates was defeated at Camden, and in consequence disgraced. Nathaniel Greene, after Washington the greatest general of the American Revolution, was appointed his successor. While awaiting Greene's arrival to take up his command Kościuszko was for some time in Virginia among the planters. He thus saw the coloured slaves at close quarters, and was brought face to face with the horrors of the slave trade. It was probably then that, with his strong susceptibility to every form of human suffering, he learnt that profound sympathy for the American negro which, seventeen years later, dictated his parting testament to the New World.
