Undaunted Courage: Meriwether Lewis, Thomas Jefferson, and the Opening of the American West by Stephen E. Ambrose

In Undaunted Courage, celebrated historian Stephen E. Ambrose recounts the epic story of the Lewis and Clark expedition—one of the most remarkable journeys in American history. Commissioned by President Thomas Jefferson, Captain Meriwether Lewis and his companion William Clark set out in 1803 to explore the vast, uncharted territory west of the Mississippi River. Drawing from Lewis’s journals and extensive historical research, Ambrose vividly recreates the adventure: the hardships, discoveries, and encounters that defined America’s early frontier spirit. It’s a sweeping narrative of ambition, endurance, and exploration that shaped the destiny of a nation.
