The Corps of Discovery’s spent the winter of 1803-1804 at an the Camp River Dubois encampment near the Wood River. It was here that Clark drilled the men to prepare them for their historic expedition. Lewis spent most of the winter in St. Louis purchasing supplies, gathering intelligence, and awaiting news that the Purchase had been completed. Finally on May 14, 1804, Clark and some forty-two men embarked up the Missouri River to meet up with Lewis in St. Charles and then continue on their historic journey.

On May 14, 1804 William Clark and the party of 38 men "Set out from Camp River a Dubois at 4 oClock P. M. and proceded up the Missouris" where they would meet up with Meriwether Lewis at St. Charles, Missouri. The expedition traveled in three boats: "the Party Consisted of 2, Self one frenchman and 22 Men in the Boat of 20 ores, 1 Serjt. & 7 french in a large Perogue, a Corp and 6 Soldiers in a large Perogue..." These three boats were the principal form of transportation the expedition used in reaching their winter of 1804-1805 camp at the Mandan villages in present day North Dakota.

The Corps of Discovery reached Fort Massac at the location of present day Paducah, Kentucky, on November 11. Secretary of War Henry Dearborn had instructed three western army units that Lewis had the authority to recruit volunteers from these garrisons and at Fort Massac Lewis and Clark chose Joseph Whitehouse and John Newman from Captain Daniel Bissell's company. Bissell also recommended to Lewis a civilian interpreter at the fort, George Drouillard, who Lewis temporarily hired and sent to collect a squad of recruits from South West Point in Tennessee.

By late July 1803 Clark wrote to Lewis that he had temporarily hired several men who met Lewis’ qualifications and that they were: "good hunters, stout, healthy, unmarried, accustomed to the woods and capable of bearing bodily fatigue to a considerable degree." When Lewis arrived at Clarksville at the Falls of the Ohio in early October of 1803, Clark was waiting for him with seven men. With John Colter and George Shannon, who were enlisted by Lewis en route to Clarksville, these men would become known as the “nine young men from Kentucky.”

The Men of the Corps of DiscoveryIn his letter to William Clark offering him co-command of the expedition, Meriwether Lewis wrote that he had been "instructed to select from any corps in the army a number of noncommissioned officers and privates not exceeding 12, who may be disposed to voluntarily enter this service . . ." Lewis also told Clark that he had been authorized to enlist civilian woodsmen. Clark then set out to recruit men near his home in Clarksville, Indiana Territory, who met the qualifications set out by Lewis. These qualifications required the men to be "good hunters, stout, healthy, unmarried, accustomed to the woods and capable of bearing bodily fatigue to a considerable degree.”

The Explorers
The two men are most associated with the Corps of Discovery: Meriwether Lewis and William Clark. Learn more about these two famous Americans. Meriwether Lewis has been called "undoubtedly the greatest pathfinder this country has ever known." William Clark was a Revolutionary War veteran and learned about wilderness skills and natural history from his older brother, George Rogers Clark.

When most people think of Lewis and Clark’s expedition they think of a western adventure. They think of the 28 month journey that started near St. Louis, traveled up the Missouri River, contacted Native Americans, braved the elements, crossed the Rockies, reached the Pacific Coast and journeyed back. Overlooked are the efforts of many along the eastern seaboard in conceiving, designing and equipping the endeavor. Thomas Jefferson had for many years thought about a navigable cross-continental trade route to the Pacific Ocean to establish an American presence in western North America.
