As a history major in undergraduate & graduate school I have serious reservations concerning this work..Make no mistake it is an excellent book...the author has done his homework. Well researched, footnoted, primary sources. Maybe even the current definite work on this such..however from the moment that, " trumpeter John Martin gallops away," the author's narrative is conjecture . To be fair the author states such in his notes proceeding his proloque - that the actions & events , " are those most likely to have occurred." It's that verbage, " most likely to have occurred," that screams out well yes maybe but we'll never really know for sure will we?
