 One such speculator, Richard Henderson (1734–1785), learned from his friend Daniel Boone that the Cherokee were interested in selling a large part of their land on the Trans-Appalachian frontier, and Henderson quickly set up negotiations with Cherokee leaders.Between March 14 and March 17, 1775, Henderson, Boone, and several associates met at Sycamore Shoals with Cherokee leaders Attakullakulla, Oconastota, Willanawaw, Doublehead and Dragging Canoe, the latter of whom sought unsuccessfully to reject Henderson's purchase of tribal lands outside the Donelson line, and departed the conference vowing to turn the lands "dark and bloody" if settlers attempted to settle upon them.The rest of the negotiations went fairly smoothly, however, and the Treaty of Sycamore Shoals was signed on March 17, 1775.
