Boone and his brother remained together in the forest for three months longer, but their ammunition getting low, on May 1st Squire Boone returned to North Carolina for a fresh supply and for horses. Daniel was thus left alone, 500 miles from home. His life was in constant peril from wild beasts and Indians. He dared not sleep in his camp, but resorted at night to a canebrake or some other hiding-place, where he lay concealed, not even kindling a fire lest its light might betray him. During these months of solitary waiting for his brother, Boone endured many privations. He had neither salt, sugar, nor flour, his sole food being game brought down by his rifle. But the return of his brother, in July, with the expected provisions, brought him much good cheer. After two years of this experience in the wilderness, Daniel Boone returned to his home on the Yadkin to make preparations for removal. By September, 1773, he had sold his farm and was ready to go with his family to settle in Kentucky. His enthusiastic reports of the fertile country he had been exploring found eager listeners, and when his party was ready to start it included, besides his wife and children, five families and forty men, with a sufficient number of horses and cattle. Unhappily they were attacked on their way by Indians, and six men, one of them Boone's eldest son, were killed. Discouraged by this setback the party returned to the nearest settlement, and for a while longer the migration westward was postponed. But it was Boone's unflinching purpose to settle in the beautiful Kentucky region. It had already become historic, for the Indians called it a "dark ground," a "bloody ground," and an old Indian Chief had related to Boone how many tribes had hunted and fought on its disputed territory. None of the Indians held an undisputed claim to the land. Nevertheless a friend of Boone, Richard Henderson, and other white men made treaties with the powerful Cherokees, who allowed them to settle here. As soon as it became certain that the Cherokees would not interfere, Henderson sent Boone in charge of thirty men to open a pathway from the Holston River, over Cumberland Gap to the Kentucky River. This is still known as the Wilderness Road, along which so many thousand settlers afterward made their way. On reaching the Kentucky River, Boone and his men set to work to build a fort on the left bank of the stream. This fort they called Boonesborough. Its four stout walls consisted in part of the outer sides of log cabins and in part of a stockade, some twelve feet high, made by thrusting into the ground stout pieces of timber pointed at the top. There were loop-holes in all the cabins, and a loop-holed block-house at each corner of the fort.
