Drawing on vivid contemporary accounts, this is a fascinating exploration of how and why the Revolutionary War descended into a brutal existential struggle.

This engrossing history of the Revolutionary War conclusively shows that those caught up in it believed they had nothing to lose by fighting without regard for the rules of so-called “civilized warfare.” The clarion call to arms “Liberty or Death” was far more than just rhetoric. At its grimmest level, it was a conflict in which military restraint was more the exception than the rule, a struggle in which combatants believed their very existence was in question. This led to an acceptance of violence against persons and property as preferable to a defeat equated with political, cultural, and even physical extinction. It was war with an expectation and acceptance of ferocity and brutality – anything to avoid defeat.

A number of historians have previously concluded that United States’ founding struggle reached a level of ferocity few Americans now associate with the movement for independence. However, these studies have described what happened, without looking in detail at why the conflict took such a violent a turn. Written by two esteemed Revolutionary War historians, War Without Mercy does exactly that. Based on years of research and enlivened by little known primary sources, this is an intriguing and fresh look at a period of history we thought we knew.

Reviews for War Without Mercy: Liberty or Death in the American Revolution

Noted military historians Mark Edward Lender and James Kirby Martin offer a fresh look at the brutality of the Revolutionary War, one they rightly call cruel and ruthless. This book breaks new ground showing why the conflict took so violent a turn, and explores the unforgiving and merciless nature of revolutionary violence. * John R. Maass, author of 'From Trenton to Yorktown: Turning Points of the Revolutionary War ' * Powdered whigs and genteel manners have no place in Lender & Martin’s War Without Mercy, the long overdue and brilliantly told story of a vicious struggle for supremacy in America. * John Buchanan, author of 'The Road to Guilford Courthouse' and 'The Road to Charleston' * Did the Revolutionary War devolve into an existential struggle divorced from the constraints of “civilized warfare”? Acclaimed historians Lender and Martin make their case in War without Mercy. Deeply thoughtful, if controversial, this is a profoundly important book. * Beth L. Hill, President & CEO, Fort Ticonderoga *
