After some months passed in Philadelphia, Kościuszko was taken over by Gates for the northern army, and sent to report upon the defences of Ticonderoga and Sugar Loaf Hill. Gates highly approved of his proposed suggestion of building a battery upon the summit of Sugar Loaf Hill; but at this moment Gates was relieved of his command, and Kościuszko's ideas were set aside for those of native Americans to whom his plan was an unheard-of innovation. The authorities soon saw their mistake. "For the love of God let Kościuszko return here," wrote Wilkinson when sent by the commander to inspect the work, "and as quickly as possible." But it was then too late. The English fleet was on Lake Champlain, and Kościuszko's design was vindicated by the British carrying it out themselves. He, meanwhile, was fortifying Van Schaick, with the result that the army of the States, retreating in disorder before Burgoyne, could retire on a safe position, Kościuszko's personal privations and discomforts were considerable. He did not so much as possess a blanket, and had perforce to sleep with Wilkinson under his. He was then sent on by Gates, who was again in command, to throw up fortifications in the defence of Saratoga. With justifiable pride the Poles point to the part played by their national hero in the victory at Saratoga which won for America not only the campaign, but her recognition as an independent nation from Louis XVI. The Americans on their side freely acknowledged that Kościuszko's work turned the scale in their favour. Gates modestly diverted the flood of congratulations of which he was the recipient by the observation that "the hills and woods were the great strategists which a young Polish engineer knew how to select with skill for my camp"; and his official report to Congress states that "Colonel Kosciuszko chose and entrenched the position," Addressing the President of Congress at the end of the year 1777, Washington, speaking of the crying necessity of engineers for the army, adds: "I would take the liberty to mention that I have been well informed that the engineer in the northern army (Kosciuszko I think his name is) is a gentleman of science and merit."[1] The plan of the fortifications that saved Saratoga is preserved in Kościuszko's own hand among Gates's papers, and traces of them could as late as 1906 be still discerned among beds of vegetables.
