Fourth Battle of Winchester

“Counterfactual questions, if kept within the parameters of what was possible at the time and place, can often help us better understand events of the past. In so doing, they can sometimes bring about a ‘paradigm shift’—a new way of thinking about history and hence of grasping its meaning... While the events described in the opening sections are fanciful, the underlying points, I believe are valid. The counterfactual events, I hope, can help us see the points with greater clarity.”—From the Preface
