"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. . . .
