"...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." -American Historical Review "...a first rate book...impressive...an imposing work..." -Journal of American History "This book is filled with enlightening information...ought to be a standard for many years to come and should be required reading for any serious Civil War military historian." -Journal of Southern History
