This book examines the relationship between civilians and warfare from the start of the Thirty Years War to the end of the Revolutionary and Napoleonic Wars. It interrogates received narratives of warfare that identify the development of modern ‘total’ war with the French Revolutionary and Napoleonic Wars, and instead considers the continuities and transformations in warfare over the course of 200 years. The book examines prisoners of war, the cultures of plunder, the tensions of billeting, and war-time atrocities throughout England, France, Spain, and the German territories. It also explores the legal practices surrounding the conduct and aftermath of war; representations of civilians, soldiers, and militias; and the philosophical underpinnings of warfare. The book probes what it meant to be a civilian in territories beset by invasion and civil war or in times when ‘peace’ at home was accompanied by almost continuous military engagement abroad. It shows civilians not only as anguished sufferers, but also directly involved with war: fighting back with shocking violence, profiting from war-time needs, and negotiating for material and social redress. Finally, the book shows us individuals and societies coming to terms with the moral and political challenges posed by the business of drawing lines between ‘civilians’ and ‘soldiers’.
