About the book

In 1803 President Thomas Jefferson selected his personal secretary, Captain Meriwether Lewis, to lead a voyage up the Missouri River to the Rockies, over the mountains, down the Columbia River to the Pacific Ocean, and back. Lewis was the perfect choice. He endured incredible hardships and saw incredible sights, including vast herds of buffalo and Indian tribes that had had no previous contact with white men.

He and his partner, Captain William Clark, made the first map of the trans-Mississippi West, provided invaluable scientific data on the flora and fauna of the Louisiana Purchase territory, and established the American claim to Oregon, Washington, and Idaho. Ambrose has pieced together previously unknown information about weather, terrain, and medical knowledge at the time to provide a colorful and realistic backdrop for the expedition.

Lewis saw the North American continent before any other white man; Ambrose describes in detail native peoples, weather, landscape, science, everything the expedition encountered along the way, through Lewis's eyes.

Lewis is supported by a rich variety of colorful characters, first of all Jefferson himself, whose interest in exploring and acquiring the American West went back thirty years. Next comes Clark, a rugged frontiersman whose love for Lewis matched Jefferson's. There are numerous Indian chiefs, and Sacagawea, the Indian girl who accompanied the expedition, along with the French-Indian hunter Drouillard, the great naturalists of Philadelphia, the French and Spanish fur traders of St.

Louis, John Quincy Adams, and many more leading political, scientific, and military figures of the turn of the century.

This is a book about a hero. This is a book about national unity. But it is also a tragedy. When Lewis returned to Washington in the fall of 1806, he was a national hero. But for Lewis, the expedition was a failure. Jefferson had hoped to find an all-water route to the Pacific with a short hop over the Rockies - Lewis discovered there was no such passage. Jefferson hoped the Louisiana Purchase would provide endless land to support farming - but Lewis discovered that the Great Plains were too dry.
