Daniel's first book is a classic. This book details the troubled history of the Army of Tennessee's artillery arm, discussing organization, weapons, tactics, battles, morale, and army politics. Daniel, ever a master of a good phrase, ends with this appropriate line: "Thus, the western Confederate long arm, the "neglected branch of the army," as Melancthon Smith referred to it, passed from existence to be remembered only by the field pieces that would one day dot the battlefield parks."
