History of the Expedition under the Command of Captains Lewis and Clark to the Sources of the Missouri, Thence Across the Rocky Mountains and Down the River Columbia to the Pacific Ocean. Performed During the Years 1804-5-6 (Complete)

On the acquisition of Louisiana, in the year 1803, the attention of the government of the United States, was early directed towards exploring and improving the new territory. Accordingly in the summer of the same year, an expedition was planned by the president for the purpose of discovering the courses and sources of the Missouri, and the most convenient water communication thence to the Pacific ocean. His private secretary captain Meriwether Lewis, and captain William Clarke, both officers of the army of the United States, were associated in the command of this enterprize. After receiving the requisite instructions, captain Lewis left the seat of government, and being joined by captain Clarke at Louisville, in Kentucky, proceeded to St. Louis, where they arrived in the month of December. Their original intention was to pass the winter at La Charrette, the highest settlement on the Missouri. But the Spanish commandant of the province, not having received an official account of its transfer to the United States, was obliged by the general policy of his government, to prevent strangers from passing through the Spanish territory. They therefore encamped at the mouth of Wood river, on the eastern side of the Mississippi, out of his jurisdiction, where they passed the winter in disciplining the men, and making the necessary preparations for setting out early in the Spring, before which the cession was officially announced. The party consisted of nine young men from Kentucky, fourteen soldiers of the United States army who volunteered their services, two French watermen—an interpreter and hunter—and a black servant belonging to captain Clarke—All these, except the last, were enlisted to serve as privates during the expedition, and three sergeants appointed from amongst them by the captains. In addition to these were engaged a corporal and six soldiers, and nine watermen to accompany the expedition as far as the Mandan nation, in order to assist in carrying the stores, or repelling an attack which was most to be apprehended between Wood river and that tribe. The necessary stores were subdivided into seven bales, and one box, containing a small portion of each article in case of accident. They consisted of a great variety of clothing, working utensils, locks, flints, powder, ball, and articles of the greatest use. To these were added fourteen bales and one box of Indian presents, distributed in the same manner, and composed of richly laced coats and other articles of dress, medals, flags, knives, and tomahawks for the chiefs—ornaments of different kinds, particularly beads, lookingglasses, handkerchiefs, paints, and generally such articles as were deemed best calculated for the taste of the Indians. The party was to embark on board of three boats: the first was a keel boat fifty-five feet long, drawing three feet water, carrying one large squaresail and twenty-two oars, a deck of ten feet in the bow, and stern formed a forecastle and cabin, while the middle was covered by lockers, which might be raised so as to form a breast-work in case of attack. This was accompanied by two perioques or open boats, one of six and the other of seven oars. Two horses were at the same time to be led along the banks of the river for the purpose of bringing home game, or hunting in case of scarcity.
