Americans often think of the Civil War as the conflict that consolidated the United States, including its military values and practices. But there was another, earlier, and more protracted struggle between “North” and “South,” beginning in the 1600s and lasting for more than two centuries, that shaped American geopolitics and military culture. Here, Eliot A. Cohen explains how the American way of war emerged from a lengthy struggle with an unlikely enemy: Canada.

In Conquered into Liberty, Cohen describes how five peoples—the British, French, Americans, Canadians, and Indians—fought over the key to the North American continent: the corridor running from Albany to Montreal dominated by the Champlain valley and known to Native Americans as the “Great Warpath.” He reveals how conflict along these two hundred miles of lake, river, and woodland shaped the country’s military values, practices, and institutions.

Through a vivid narration of a series of fights— woodland skirmishes and massacres, bloody frontal assaults and fleet actions, rear-guard battles and shadowy covert actions—Cohen explores how a distinctively American approach to war developed along the Great Warpath. He weaves together tactics and strategy, battle narratives, and statecraft, introducing readers to such fascinating but little-known figures as Justus Sherwood, loyalist spy; Jeduthan Baldwin, self-taught engineer; and La Corne St. Luc, ruthless partisan leader. And he reintroduces characters we thought we knew—an admirable Benedict Arnold, a traitorous Ethan Allen, and a devious George Washington. A gripping read grounded in serious scholarship, Conquered into Liberty will enchant and inform readers for decades to come.

“Conquered Into Liberty is beautiful narrative history: The author is a poetic and evocative storyteller. But the book is also valuable for the lessons it imparts and the heritage it conveys. The experience along the Great Warpath has seeped into the American character and helped prepare subsequent warriors to appreciate Washington’s famous declaration: ‘If you wish for peace, prepare for war.’ The Great Warpath’s legacy helps our soldiers know that one of the obligations of citizenship is to understand the character of war.” –Josiah Bunting, The Washington Post
