Thomas Jefferson to Benjamin Rush
"I wish to mention to you in confidence that I have obtained authority from Congress to undertake the long desired object of exploring the Missouri & whatever river, heading with that, leads into the Western ocean. About 10. chosen woodsmen headed by Capt. Lewis my secretary, will set out on it immediately & probably accomplish it in two seasons. Capt. Lewis is brave, prudent, habituated to the woods, & familiar with Indian manners & character. . . . It would be very useful to state for him those objects on which it is most desirable he should bring us information. For this purpose I ask the favor of you to prepare some notes of such particulars as may occur in his journey & which you think should draw his attention & enquiry" (Jackson, 1:18-19).
Meriwether Lewis was born in Virginia in 1774. At age 18, he was managing his plantation in Virginia. He joined the militia in 1794 and the U.S. Army in 1795. Lewis served with General Anthony Wayne and was present at the signing of the Treaty of Greenville (1795). He served in a rifle company commanded by Captain William Clark. Lewis was promoted to captain in 1800, and, in 1801, President Thomas Jefferson asked him to serve as his private secretary in Washington. Jefferson appointed Lewis to head the expedition to the Northwest in 1803. Lewis was appointed governor of the Louisiana Territory in 1807. He committed suicide in 1809 leaving the journals of the expedition unpublished (Ambrose, 19, 21, 29, 37, 42, 45, 50, 59, 80, 415, 465, 467).
