This book is an historical analysis of Stewart's Division during the Battle of Chickamauga, l9-20 September 1863. It determines what tactical formations Stewart and his brigades employed, how this affected casualty totals and their significance to the outcome of the engagements in Stewart's sector. This book concludes that Stewart's tactical formations contributed to his success on the nineteenth. Stewart's failure on the twentieth was more the responsibility of a higher echelon commander. In the final analysis Stewart's leadership abilities were more a contributor to the success of the division than the tactics that were employed.
