In the meantime, the restless Boone, impatient over the delay in the consummation of Judge Henderson's plans, resolved to establish himself in Kentucky upon his own responsibility. Heedless of the question of title and the certain hazards incident to invading the territory of hostile savages, Boone designated a rendezvous in Powell's Valley where he and his party of five families were to be met by a band under the leadership of his connections, the Bryans, and another company led by Captain William Russell, a daring pioneer of the Clinch Valley. A small detachment of Boone's party was fiercely attacked by Shawanoes in Powell's Valley on October 10, 1773, and almost all were killed, including sons of Boone and Russell, and young John and Richard Mendenhall of Guilford County, North Carolina. As the result of this bloody repulse, Boone's attempt to settle in Kentucky at this time was definitely abandoned. His failure to effect a settlement in Kentucky was due to that characteristic disregard of the territorial rights of the Indians which was all too common among the borderers of that period. This failure was portentous of the coming storm. The reign of the Long Hunters was over. Dawning upon the horizon was the day of stern adventurers, fixed in the desperate and lawless resolve to invade the trans-Alleghany country and to battle savagely with the red man for its possession. More successful than Boone was the McAfee party, five in number, from Botetourt County, Virginia, who between May 10th and September 1, 1773, safely accomplished a journey through Kentucky and carefully marked well-chosen sites for future location. [138] An ominous incident of the time was the veiled warning which Cornstalk, the great Shawanoe chieftain, gave to Captain Thomas Bullitt, head of a party of royal surveyors, sent out by Lord Dunmore, Governor of Virginia. Cornstalk at Chillicothe, June 7, 1773, warned Bullitt concerning the encroachments of the whites, "designed to deprive us," he said, "of the hunting of the country, as usual ... the hunting we stand in need of to buy our clothing." During the preceding summer, George Rogers Clark, an aggressive young Virginian, with a small party, had descended the Ohio as low as Fish Creek, where he built a cabin; and in this region for many months various parties of surveyors were busily engaged in locating and surveying lands covered by military grants. Most significant of the ruthless determination of the pioneers to occupy by force the Kentucky area was the action of the large party from Monongahela, some forty in number, led by Captain James Harrod, who penetrated to the present Miller County, where in June, 1774, they made improvements and actually laid out a town.
