The two officers chosen to carry through the work belonged to families already honorably distinguished for service on the Western border. One was Captain Meriwether Lewis, representatives of whose family had served so prominently in Dunmore's war; the other was Lieutenant (by courtesy Captain) William Clark, a younger brother of George Rogers Clark. [Footnote: He had already served as captain in the army; see Coues' edition of the "History of the Expedition," lxxi.] Clark had served with credit through Wayne's campaigns, and had taken part in the victory of the Fallen Timbers. [Footnote: See his letters, quoted in Chap. II. There is a good deal of hitherto unused material about him in the Draper MSS.] Lewis had seen his first service when he enlisted as a private in the forces which were marshalled to put down the whisky insurrection. Later he served under Clark in Wayne's army. He had also been President Jefferson's private secretary. Their Party. The young officers started on their trip accompanied by twenty-seven men who intended to make the whole journey. Of this number one, the interpreter and incidentally the best hunter of the party, was a half-breed; two were French voyageurs; one was a negro servant of Clark; nine were volunteers from Kentucky; and fourteen were regular soldiers. All, however, except the black slave, were enlisted in the army before starting, so that they might be kept under regular discipline. In addition to these twenty-seven men there were seven soldiers and nine voyageurs who started only to go to the Mandan villages on the Missouri, where the party intended to spend the first winter. They embarked in three large boats, abundantly supplied with arms, powder, and lead, clothing, gifts for the Indians, and provisions. The starting point was St. Louis, which had only just been surrendered to the United States Government by the Spaniards, without any French intermediaries. The explorers pushed off in May, 1804, and soon began stemming the strong current of the muddy Missouri, to whose unknown sources they intended to ascend. For two or three weeks they occasionally passed farms and hamlets. The most important of the little towns was St. Charles, where the people were all Creoles; the explorers in their journal commented upon the good temper and vivacity of these _habitants_, but dwelt on the shiftlessness they displayed and their readiness to sink back towards savagery, although they were brave and hardy enough. The next most considerable town was peopled mainly by Americans, who had already begun to make numerous settlements in the new land. The last squalid little village they passed claimed as one of its occasional residents old Daniel Boone himself.
