To Lewis there befell other adventures. Once, while he was out with three men, a party of eight Blackfoot warriors joined them and suddenly made a treacherous attack upon them and strove to carry off their guns and horses. But the wilderness veterans sprang to arms with a readiness that had become second nature. One of them killed an Indian with a knife thrust; Lewis himself shot another Indian, and the remaining six fled, carrying with them one of Lewis' horses, but losing four of their own, which the whites captured. This was the beginning of the long series of bloody skirmishes between the Blackfeet and the Rocky Mountain explorers and trappers. Clark, at about the same time, suffered at the hands of the Crows, who stole a number of his horses. He is Shot by one of his Own Party. None of the party were hurt by the Indians, but some time after the skirmish with the Blackfeet Lewis was accidentally shot by one of the Frenchmen of the party and suffered much from the wound. Near the mouth of the Yellowstone Clark joined him, and the reunited company floated down the Missouri. Before they reached the Mandan villages they encountered two white men, the first strangers of their own color the party had seen for a year and a half. These were two American hunters named Dickson and Hancock, who were going up to trap the head-waters of the Missouri on their own account. They had come from the Illinois country a year before, to hunt and trap; they had been plundered, and one of them wounded, in an encounter with the fierce Sioux, but were undauntedly pushing forwards into the unknown wilderness towards the mountains. They Meet Two Hunters. These two hardy and daring adventurers formed the little vanguard of the bands of hunters and trappers, the famous Rocky Mountain men, who were to roam hither and hither across great West in lawless freedom for the next three quarters of a century. They accompanied the party back to the Mandan village; there one of the soldiers joined them, a man name Colter, so fascinated by the life of the wilderness that he was not willing to leave it, even for a moment's glimpse of the civilization, from which he had been so long exiled. [Footnote: For Colter, and the first explorers of this region, see "The Yellowstone National Park," by Captain H. M. Chittenden.] The three turned their canoe up-stream, while Lewis and Clark and the rest of the party drifted down past the Sioux. They Return to St. Louis. The further voyage of the explorers was uneventful. They had difficulties with the Sioux of course, but they held them at bay. They killed game in abundance, and went down-stream as fast as sails, oars, and current could carry them. In September they reached St. Louis and forwarded to Jefferson an account of what they had done. After-Careers of Lewis and Clark.
