The Secret War for the Union : The Untold Story of Military
Intelligence in the Civil War
Previous histories of the Civil War have explained victory of defeat in terms of the skill of commanders, the fighting qualities of the troops, and resources of men and material. Intelligence has been largely ignored, not because it wasn't important - Lincoln called it the most difficult problem faced by the Union - but because so little has been known about it. At the end of the war, most intelligence records dissapeared and remained hidden for almost a century, until Edwin Fishel uncovered them during the forty years of research that went into this monumental book
The Secret War for the Union is unique among Civil War histories in its reliance upon original, previously unknown sources. It is the first book to examine in detail the impact of intelligence, and this intelligence explaination alters, sometimes radicaly, history's understanding of virtually every campaign. Both enthralling and authoritative, The Secret War for the Union is one of the most important books ever published about the Civil War.
