"Mountcastle argues persuasively for the inclusion of ‘punitive war,’ alongside hard and total war, as a distinct mode of Union war-making against the Confederacy. . . . There is no question that he offers an important concept that at once broadens and deepens our understanding of the multitude of conflicts unleashed between 1861 and 1865. . . . [The book is] a wonderful reflection on the limitations of military retaliation against civilian populations in either quelling insurgencies or providing for a lasting peace post-bellum."—On Point
"Mountcastle’s book makes an important contribution to recent debates over the physical destructiveness and social impact of the Civil War. . . . [He] makes a persuasive case that the ‘guerrilla problem’ was not a sideshow of the conflict, but rather a central factor in its evolution from conciliation to hard war. . . . This is a book that all students of the American Civil War will read with great profit,. Engaging a central issue in the historical interpretation of the conflict, it does so with clarity and fresh evidence."—Army History

"In his new look at a complex problem, U.S. Major Mountcastle contends that Confederate guerrilla warfare during the Civil War grew from the bottom up; that Union reprisals to it began in the ranks not as an order from higher headquarters in the western theater, specifically in Missouri, as early as 1861. Nominally a Union state, Missouri was divided from the start, so much so that its new governor was appointed, not elected. It was soon under martial law and a succession of commanders, including Grant and Sherman, were soon convinced that retaliatory punitive action against Confederate tactics was justified and that it must extend to civilians and their property. Hence the total war that resulted. This is a valuable close-up study of the ugly side of war, best appreciated by specialists."—Library Journal
“Mountcastle demonstrates, with powerful insight, deep archival research, and crisp writing, the central role of guerilla warfare during the Civil War. . . . This is a close-up view of the real Civil War, unrelentingly savage and utterly inhumane.”—Michael Fellman, author of In the Name of God: Reconsidering Terrorism in American History
“This excellent combination of storytelling and analysis explains better than any previous work how the Confederacy’s guerrilla war influenced Union military policy.”—Daniel E. Sutherland, author of Seasons of War: The Ordeal of a Confederate Community, 1861–1865
“Packs as much punch as the Union’s punitive war itself.”—Brian S. Wills, author of The War Hits Home
“Most historians merely lay out facts in chronological order, relying on good research. Clay Mountcastle goes several steps further. He repeatedly states his central premise—that Confederate guerrilla activity was the proximate cause of the development of Union ‘hard war’ policy. He supports that premise with solid archival research and then adds great historiographical research to point out that previous historians have not taken their analysis far enough to connect the two dots. This book is military analysis at its best.”—S. Waite Rawls III, President and CEO, Museum of the Confederacy
