In the particular purchase made by Henderson and his coadjutors, the benefits thereof were afterwards claimed by the authorities of Virginia and North Carolina for those States, as the successors of the royal prerogative within their respective limits. In consideration, however, of Henderson's valuable services on the frontier, and in compensation for his large expenditures of money in negotiating the purchase, the legislature of North Carolina in 1783 granted to him and those interested with him a tract of 200,000 acres,[33] constituting a strip 4 miles in width from old Indian town on Powell's River to the mouth, and thence a strip down the Clinch River for quantity 12 miles in width. The legislature of Virginia also granted them a tract of like extent upon the Ohio River, opposite Evansville, Indiana.[34] _Treaties and purchases of 1777._--In consequence of continued hostilities between the Cherokees and the settlers, General Williamson in 1776 marched an army from South Carolina and destroyed the towns of the former on Keowee and Tugaloo Rivers. General Rutherford marched another force from North Carolina and Colonel Christian a third from Virginia, and destroyed most of their principal towns on the Tennessee.[35] At the conclusion of hostilities with the Cherokees, following these expeditions, a treaty with them was concluded May 20, 1777, at De Witt's or Duett's Corners, South Carolina, by the States of South Carolina and Georgia. By the terms of this treaty the Indians ceded a considerable region of country upon the Savannah and Saluda Rivers,[36] comprising all their lands in South Carolina to the eastward of the Unacaye Mountains. Two months later (July 20) Commissioners Preston, Christian, and Shelby, on the part of Virginia, and Avery, Sharpe, Winston, and Lanier, for North Carolina, also concluded a treaty with the Cherokees, by which, in the establishment of a boundary between the contracting parties, some parts of "Brown's line," previously mentioned, were agreed upon as a portion of the boundary, and the Indians relinquished their lands as low down on Holston River as the mouth of Cloud's Creek. To this treaty the Chicamauga band of Cherokees refused to give their assent.[37]
