In reviewing the hardcover, the NY Times well understood author Nelson Lankford's use of narrative to undo the corruption of narrative:
Historians tell stories. That is their profession. And the goal of storytelling is to impose order on a disorderly array of facts, to steer events toward a conclusion that seems satisfyingly final, even inevitable. In “Cry Havoc!” Nelson D. Lankford disrupts the process.The idea that "historians tell stories" is nonsense, of course, unless one counts that along with other items like "Historians eat meals" and "Historians rest at night." But you get the larger idea.
I think "What If" - as a hook - will provide the lever of Archimedes in Civil War history - one that moves the discerning readers off the world of craptastic pop history.
p.s. Harry has posted on this book and finds the "what-if" factor weak.
Each chapter identifies various turning points at which, if things had been handled differently, events might have been profoundly affected. The problem is that the alternative choices are seldom specific, and the alternative outcomes are rarely identified. [...] Another problem is the failure of the author to recognize that the fundamental difference between the Union and the seceded states were their mutually exclusive objectives - Union or Disunion.I think these matters are worth a second look in another post.
