A biography of Meriwether Lewis that relies heavily on the journals of both Lewis and Clark, this book is also backed up
by the author's personal travels along Lewis and Clark's route to the Pacific. Ambrose is not content to simply
chronicle the events of the "Corps of Discovery" as the explorers called their ventures. He often pauses to assess the
military leadership of Lewis and Clark, how they negotiated with various native peoples and what they reported to
Jefferson. Though the expedition failed to find Jefferson's hoped for water route to the Pacific, it fired interest
among fur traders and other Americans, changing the face of the West forever.
