Acts of War: The Behavior of Men in Battle by Richard Holmes

In Acts of War, military historian Richard Holmes explores the human experience of combat with penetrating insight and realism. Drawing from first-hand accounts across centuries of warfare—from the trenches of World War I to the jungles of Vietnam—Holmes examines how ordinary men endure extraordinary conditions of fear, exhaustion, and violence. Through psychology, history, and storytelling, he reveals what drives soldiers to fight, how they cope with the moral chaos of war, and what happens when discipline, loyalty, and survival instincts collide. The result is a profound study of courage, fear, and the fragile line between heroism and horror.
