From one of the most important Army officers of his generation, a memoir of the military’s revolution in counterinsurgency warfare

Delivering a profound education in modern warfare, John Nagl’s Knife Fights is essential reading for anyone who cares about the fate of America’s soldiers and the purposes for which their lives are put at risk.

As an army tank commander in the first Gulf War, Nagl was an early convert to the view that America’s greatest future threats would come from asymmetric warfare—guerrillas, terrorists, and insurgents. His Oxford thesis on the lessons of Vietnam—eventually published as a book called Learning to Eat Soup with a Knife—became the bible of the counterinsurgency movement. But it would take 9/11 and the botched aftermath of the Iraq invasion to give his ideas contemporary relevance. After a year’s hard fighting in Iraq’s Anbar Province, where Nagl served as operations officer of a tank battalion in the 1st Infantry Division, he was asked by General David Petraeus to coauthor the new Army and Marine Corps counterinsurgency field manual—rewriting core doctrine that would change the course of two wars and the thinking of an army. Knife Fights is the definitive account of counterinsurgency and its consequences by the man who was the doctrine’s leading architect.

This is a book about modern wars and how they affect the lives of young men and women. It is a tale of wars that needed to be fought and wars that were not necessary but that happened nonetheless, at enormous cost in blood and treasure. It is also an intellectual coming-of-age story, that of both the author and the institution to which he devoted most of his adult life, the American military. It is a book about counterinsurgency and its journey from the far periphery of U.S. military doctrine to its center, for better and, some would argue, for worse. It is also, then, a book about America’s role in the world, and specifically about when and how we use military force abroad in the name of national security.

The book largely takes the form of a memoir, which feels somewhat self-indulgent to me—I was very much more shaped by than shaper of the events this book relates. But my hope is that following the arc of my own learning curve will be the easiest way for a reader to understand the broader story of the American military’s radical adaptation to a world of threats very different from those involving nuclear weapons and Soviet tanks massed at the Fulda Gap that I studied at West Point a generation ago. Following that arc will also help to explain why, after decades of responsibility for the lives of American soldiers, I have recently shouldered the responsibility to prepare another generation of young men for a life of service far from the battlefield, in the classrooms and on the playing fields of friendly strife as the ninth headmaster of The Haverford School.
