The following year four young men from the Yadkin, Benjamin Cutbird, John Stewart (Boone's brother-in-law who afterwards accompanied him to Kentucky), John Baker, and James Ward made a remarkable journey to the westward, crossing the Appalachian mountain chain over some unknown route, and finally reaching the Mississippi. The significance of the journey, in its bearing upon westward expansion, inheres in the fact that while for more than half a century the English traders from South Carolina had been winning their way to the Mississippi along the lower routes and Indian trails, this was the first party from either of the Carolinas, as far as is known, that ever reached the Mississippi by crossing the great mountain barrier. When Cutbird, a superb woodsman and veritable Leatherstocking, narrated to Boone the story of his adventures, it only confirmed Boone in his determination to find the passage through the mountain chain leading to the Mesopotamia of Kentucky. Such an enterprise was attended by terrible dangers. During 1766 and 1767 the steady encroachments of the white settlers upon the ancestral domain which the Indians reserved for their imperial hunting-preserve aroused bitter feelings of resentment among the red men. Bloody reprisal was often the sequel to such encroachment. The vast region of Tennessee and the trans-Alleghany was a twilight zone, through which the savages roamed at will. From time to time war parties of northern Indians, the inveterate foes of the Cherokees, scouted through this no-man's land and even penetrated into the western region of North Carolina, committing murders and depredations upon the Cherokees and the whites indiscriminately. During the summer of 1766, while Boone's friend and close connection, Captain William Linville, his son John, and another young man, named John Williams, were in camp some ten miles below Linville Falls, they were unexpectedly fired upon by a hostile band of Northern Indians, and before they had time to fire a shot, a second volley killed both the Linvilles and severely wounded Williams, who after extraordinary sufferings finally reached the settlements. [93] In May, 1767, four traders and a half-breed child of one of them were killed in the Cherokee country. In the summer of this year Governor William Tryon of North Carolina laid out the boundary line of the Cherokees, and upon his return issued a proclamation forbidding any purchase of land from the Indians and any issuance of grants for land within one mile of the boundary line. Despite this wise precaution, seven North Carolina hunters who during the following September had lawlessly ventured into the mountain region some sixty miles beyond the boundary were fired upon, and several of them killed, by the resentful Cherokees.
