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.

Through the whole campaign of the Carolinas, the most brilliant and the most hardly won of the American War, Kościuszko was present. When Greene arrived he found himself at the head of an army that was starving. His troops had literally not enough clothing required for the sake of decency. He was without money, without resources. He resolved to retire upon the unknown Pedee river. Immediately upon his arrival he sent Kościuszko up the river with one guide to explore its reaches and to select a suitable spot for a camp of rest, charging him with as great celerity as he could compass. Kościuszko rapidly acquitted himself of a task that was no easy matter in that waste of forest and marsh. In the words of an American historian: "The surveying of the famous Kościuszko on the Pedee and Catawba had a great influence on the further course of the campaign." The campaign was carried on in a wild country of deep, roaring rivers, broken by falls, and often visited by sudden floods. The frequently impassable swamps breathed out poisonous exhalations. Rattle-snakes and other deadly reptiles lurked by the wayside. Great were the hardships that Kościuszko, together with the rest of the army, endured. There were no regular supplies of food, tents and blankets ran out, the soldiers waded waist-deep through rushing waters. Often invited to Greene's table, where the general entertained his officers with a kindliness and cordiality that atoned for the poor fare which was all that he could offer them, Kościuszko was regarded with strong affection and admiration by a man who was himself worthy of the highest esteem. Kościuszko's office, after the survey of the river, was to build boats for the perilous transport of the army over the treacherous and turbulent streams of the district. Greene writes: "Kościuszko is employed in building flat-bottomed boats to be transported with the army if ever I shall be able to command the means of transporting them."[1] The boats of Kościuszko's devising contributed to the saving of Greene's army in that wonderful retreat from Cornwallis, which is among the finest exploits of the War of Independence. Again his skill came prominently forward when Greene triumphantly passed the Dan with Cornwallis on his heels, and thus definitely threw off the British pursuit. Kościuszko was then despatched to fortify Halifax, but was soon recalled to assist in the siege of Ninety Six, a fort built with heavy stockades originally as a post of defence against the Red Indians. The night before the siege began Greene with Kościuszko surveyed the English works. It was dark and rainy, and they approached the enemy so close that they were challenged and fired at by the sentries. The mining operations that Kościuszko directed were of an almost insuperable difficulty, and his Virginian militiamen struck. By his persuasive and sympathetic language Kościuszko rallied them to the work; but finally Greene abandoned the siege.

When the campaign changed to guerilla warfare Kościuszko fought as a soldier, not as an engineer. At the battle of Eutaw Springs, where the licence of the American soldiers pillaging the British camp and murdering the prisoners lost Greene a decisive victory, we hear of Kościuszko as making desperate attempts to restrain a carnage which horrified his humane feelings, and personally saving the lives of fifty Englishmen. Peace and the defeat of Great Britain were in the air, but hostilities still dragged on, and Kościuszko fought through 1782 near Charleston with distinction. After the gallant Laurens had fallen, his post of managing the secret intelligence from Charleston passed to Kościuszko. "Kosciuszko's innumerable communications," says the grandson and biographer of Greene, "exhibit the industry and intelligence with which he discharged that service."[1] Kościuszko possessed all the Polish daring and love of adventure. He would sally forth to carry off the English horses and cattle that were sent to pasture under guard, protected by English guns from the fort. He succeeded in capturing horses, but the cattle were too closely protected. Or, accompanied by an American officer named Wilmot, he would cross the river to watch or harry the English on James' Island. One of these expeditions, when Kościuszko and his companion attacked a party of English woodcutters, has the distinction of being the last occasion on which blood was shed in the American War. They were surprised by an ambuscade, and Wilmot was killed. At length Charleston fell. On December 14, 1782, the American army entered the town in a triumphal procession, in which Kościuszko rode with his fellow-officers, greeted by the populace with flowers and fluttering kerchiefs and cries of "Welcome!" and "God bless you!" Greene's wife, a sprightly lady who kept the camp alive, had joined him outside Charleston. Her heart was set on celebrating the evacuation of Charleston by a ball, and, although her Quaker husband playfully complained that such things were not in his line, she had her way. The ball-room was decorated by Kościuszko, who adorned it with festoons of magnolia leaves and with flowers cunningly fashioned of paper.

Peace with England was now attained. Kościuszko had fought for six years in the American army. The testimony of the eminent soldier in whose close companionship he had served, whose hardships he had shared, whose warmest friendship he had won, that of Nathaniel Greene, best sums up what the Pole had done for America and what he had been to his brother-soldiers. "Colonel Kosciuszko belonged"—thus Greene—"to the number of my most useful and dearest comrades in arms. I can liken to nothing his zeal in the public service, and in the solution of important problems nothing could have been more helpful than his judgment, vigilance and diligence. In the execution of my recommendations in every department of the service he was always eager, capable, in one word impervious against every temptation to ease, unwearied by any labour, fearless of every danger. He was greatly distinguished for his unexampled modesty and entire unconsciousness that he had done anything unusual. He never manifested desires or claims for himself, and never let any opportunity pass of calling attention to and recommending the merits of others."[1] All those who had been thrown together with him in the war speak in much the same manner. They notice his sweetness and uprightness of soul, his high-mindedness and delicate instincts, his careful thought for the men under his command. Even Harry Lee ("Light Horse Harry"), while carping at Kościuszko's talents, to the lack of which, with no justification, he ascribes Greene's failure before Ninety Six, renders tribute to his engaging qualities as a comrade and a man. But Kościuszko's services did not in the first instance receive the full recognition that might have been expected from the new Republic. He alone of all the superior officers of the Revolution received no promotion other than that given wholesale by Congress, and was forced to apply personally to Washington to rectify the omission. In language not too cordial, Washington presented his request to Congress, which conferred upon Kościuszko the rank of brigadier-general with the acknowledgment of its "high sense of his long, faithful and meritorious services." The recently founded patriotic Society of the Cincinnati, of which Washington was the first president, elected Kościuszko as an honoured member. Its broad blue and white ribbon carrying a golden eagle and a representation of Cincinnatus before the Roman Senate, with the inscription: "Omnia relinquit servare Rempublicam," is often to be seen in the portraits of Kościuszko, suspended on his breast.
