This Vast Enterprise

f 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. Craig Fehrman spent five years visiting more than thirty archives, interviewing more than a hundred sources, and collecting oral history passed down over centuries. He came to see that the success of Lewis and Clark depended on much more than just Lewis and Clark. We all know Sacajawea, and some of us know York, the Black man Clark enslaved. But here we meet John Ordway, a working-class soldier who fought grizzlies and towed the captains’ hulking barge. We hear from Wolf Calf, a Blackfoot teenager who watched his friend die in a battle with Lewis and his men.

Each chapter moves to a different person’s point of view, describing their desires and contradictions. We see Thomas Jefferson operating in an age of bitter partisan unrest—his secret political maneuvers to fund the expedition, revealed here for the first time, are a case study in presidential power. We witness the strategy and strength of Black Buffalo, completely upending our understanding of Lakota-American diplomacy. York, in his chapters, finds ways to wield power and make choices in an era that didn’t allow him much of either. Clark is not a folksy Kentuckian but a student of the Enlightenment. (Fehrman discovered his college notebook; no previous biographer even realized that he went to college.) Lewis is someone willing to sacrifice everything for his country and his mentor, Jefferson.
