The American Civil War may have been more consequential to American history (and its global supremacy) than its Revolutionary War and participation in all other world wars. The influence of this war is not just reduced to the victory of the north and its economic infrastructure, but the fact of Union success ushered in the notion of 'what it means to be American' that even the revolution could not instill.  European military historian Jeremy Black reorients readers to see what was extraordinary in the civil war of 'the American colonies' and why this was warfare unlike anything that could be properly understood on the world stage at that time. He also examines with expertise the role of foreign powers (or lack thereof).  Black's treatment might be the doom of civil war counterfactuals. Was the south destined to fail? Was it weaker motive, faulty strategy, or lack of European support? Was the north just lucky, or possessed of foresight and providential endowment? Black dispels romanticism and sentimentalist hindsight––the American Civil War is unparalleled in many respects, but it is not without clear lessons in warcraft, diplomacy, and cultural–economic impasse.  Furthermore, Black's Civil War is a new resource that teaches, reaffirms, and reminds readers of the intensity of the American past––in both error and idealistic impulse––that might continue to guide us to the best future and avoid the lose-lose circumstances of a civil war. Black's acumen for historical review in this case renders a kind of warning: May the leaders of men in the future come to a better way of self-realization than give way to the internal conflict that pits father against son, and sister against brother. But if he must engage, at least understand the distinction between war and politics.  Black's objective and concise account is a treasure for students and experts alike who need clarity and insight without too much of an investment. The take-away is an appreciation for the American spirit that civil strife petrified and an understanding of the tactical progression of this conflict and the context of combat of that era.
