<br/><br/> The first book to examine in detail the impact of intelligence and intelligence explanation alters, sometimes radically, history's understanding of virtually every campaign.  The first authentic history of military intelligence in the civil war.  These books are descended from the memoirs of men and women who claimed not all of them truthfully to have been spies for the Union or the Confederacy.
