The American Civil War and the Origins of Modern Warfare" . . . a major contribution to our knowledge of the place of the Civil War in the history of warfare. . . . I have long hoped for a sound history of Civil War military staffs . . . I need hope no more; Hagerman has covered this subject also, with the same assured expertness that he gives to tactics and technology." Russell F. Weigley " . . . this fine book deserves a place on the shelves of all military historians in this country and abroad."
