General William Clark (1770-1838)

William Clark came to Kentucky with his parents in 1784. In 1789 he fought the Indians in an expedition led by Col. John Hardin. In 1790 he was sent on a mission to the Creek and Cherokee nations and in 1791 served as an ensign and acting lieutenant on the expeditions under general Scott and Wilkinson against the native Americans on the Wabash. General Washington commissioned him a first lieutenant in the 4th Sub Legion under General Wayne in March 1793.

William came home to Kentucky in 1796 and lived with his parents at Mulberry Hill. When they died, he inherited the homestead but sold it to his brother, Jonathan, in 1800. He then moved to Clarksville, Indiana, with his brother, George Rogers Clark.

In 1803, President Thomas Jefferson commissioned Meriwether Lewis and William Clark to make a western expedition to establish an American presence in the far northwest; to investigate a water passage to the Western Sea; to map and investigate the new Louisiana purchase; to report the culture, commerce, and capabilities of the many native-American tribes of the area; and to observe and collect botanical and biological specimens.

Members of the expedition assembled at Louisville, KY, in October, 1803, and moved on to camp above St. Louis on the east bank of the Mississippi for the winter, pending signing of the Louisiana Purchase. Upon reaching the native Mandan villages in present-day South Dakota, they acquired the services of Toussaint Charbonneau, a French trader, and his pregnant 15-year-old Shoshone wife, Sacagewea (Suh-COG-uh-wea, "Bird Woman"), as interpreters, not as guides.

By June of 1805, Lewis and Clark and their party were at the Great Falls of present-day Montana and made a difficult 10-day portage around it. Obtaining horses from the Shoshones, they crossed the Bitterroot Mountains, came down the Columbia River to the Pacific Ocean in late November, and wintered at Fort Clatsop (Oregon). The expedition returned to St. Louis on September 20, 1806, to the astonishment of many who had given them up for dead months before. After disbanding most of the company, Lewis and Clark returned east in October, pausing for three weeks at Locust Grove, home of Clark's sister, Lucy Clark Croghan. Lewis then moved on to report to the President in Washington City where Clark later joined him.

After Clark's marriage in 1808, he was appointed Indian agent at St. Louis. In 1813, he was made Governor of the Missouri Territory. In 1822, President Monroe appointed him Superintendent of Indian Affairs to establish and secure treaties with the western tribes. He died in St. Louis in 1838, esteemed by all who knew him.
