"In 1806, when Meriwether Lewis and William Clark return from their yearslong 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 bold and 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 This Vast Enterprise introduces us to John Ordway, a working-class soldier who fought fearsome grizzlies and towed the captains' hulking barge. It introduces us to Wolf Calf, a Blackfoot teenager who watched his friend die in a tense battle with Lewis and his men. To capture this cast of characters, each chapter in This Vast Enterprise moves to a different person's point of view, describing their desires and contradictions with an unprecedented level of care. One chapter shows 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. Another chapter shows 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, his mission, and his mentor, Jefferson; in Fehrman's subtle yet heartbreaking analysis, Lewis's legendary strengths are inseparable from his lifelong weaknesses. 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 dramatic hailstorms and flash floods, life-threatening frostbite and infections, rattlesnakes and rabid wolves, with the Spanish cavalry in fierce pursuit. Fehrman bal­ances the story's inherent adventure with the humanity of its protagonists." -- Provided by publisher.
