Undaunted Courage by Stephen Ambrose

Ambrose, Stephen E. Undaunted Courage: Meriwether Lewis, Thomas Jefferson, and the Opening of the American West. 1996. New York: Touchstone, 1997.

Undaunted Courage is a biography of Meriwether Lewis. It is also, to a large extent, an account of Lewis’ expedition, co-led by William Clark, up the Missouri River, across the Rocky Mountains, down the Columbia River to the Pacific Coast and back again.


The Lewis and Clark expedition, the bicentennial of which was celebrated in 2004 through 2006, is rightly presented as the centerpiece of Lewis’ life. Ambrose shows how Lewis’ early life in the plantations and wilderness of Virginia, as a militia officer during the Whiskey Rebellion and under the political tutelage of Thomas Jefferson uniquely prepared Lewis to lead a company of explorer-soldiers with a broad mission. His life after the expedition was brief and troubled.

The western exploration, beginning in 1804 and ending in 1806, is the major focus of the narrative. It was more than simply a trip. Lewis and Clark were charged with scientific observation (particularly geography, botany and zoology), Indian diplomacy, establishing trade, and what might be considered a touch of espionage. With the exception of Indian policy, Lewis, Clark and their men performed admirably.

Lewis, throughout the mission and afterward, wanted to make it clear that he and Clark had equal parts in the leadership of the expedition. It is extraordinary that this worked so well. One gets the impression for the book that Lewis was the senior of these equals, which may explain it. Even so, Lewis seemed to prefer the close companionship of trusted peers and friends.

Lewis achieved great success while still relatively young, in his early thirties. Early success can be tough, but Lewis seems like a man who can handle tough situations. However, his few years of life after the expedition seem to be characterized by failure. Certainly, the political situation in the Louisiana Territory, where Lewis was appointed governor, was very difficult, and he may not have been cut out to be a politician and bureaucrat. However, he left important matters that were easily within his grasp undone. Notably, he never published the expedition journals, which more than anything else may have sealed his fame, supported his policies and multiplied the fruit of his exceptional labor.

The final years of Lewis’ life, which ended in suicide, raises many unanswered, and possibly unanswerable, questions. Even so, Ambrose’s biography of the man is an interesting story, and sometime and exciting tale of his great adventure.
