This Vast Enterprise
A New History of Lewis & Clark
by Craig Fehrman
A major revisionist history of the Lewis and Clark expedition: For the first time in a generation, This Vast Enterprise offers a fresh and more accurate account of one of the most important episodes in American history, humanizing forgotten figures and shattering long-held myths.
In 1806, when Meriwether Lewis and William Clark return from their journey—having led the Corps of Discovery across eight thousand miles of rapids, mountains, forests, and ravines—they bring an incredible tale starring themselves as courageous explorers, skilled survivalists, underrated scientists, and peaceful ambassadors. While there is truth in those descriptions, there is also distortion.
From one of the most exciting new historians to emerge in the past decade, This Vast Enterprise offers a novel take on the expedition: a gripping narrative that draws on lost documents, stunning analysis, and Native perspectives. Each chapter moves to a different person’s point of view, describing their desires and contradictions.
In the end, the captains are men who needed help—from Sacajawea, from the Corps, and from each other. Mile after mile, the expedition pushes on through hailstorms and flash floods, frostbite and infections, rattlesnakes and rabid wolves, with the Spanish cavalry in fierce pursuit. Fehrman balances the story’s adventure with the humanity of its protagonists. The result is a thrilling reminder that even the most familiar moments in history can still surprise us.
