This study examines the operational insights offered by the analysis of the Tullahoma, or Middle Tennessee, Campaign of 1863. The thesis uncovers these operational insights by examining how Major General William S. Rosecrans, commander of the Army of the Cumberland, and General Braxton Bragg, commander of the Army of Tennessee, planned for and conducted the nine day campaign. This study of both commanders planning and execution of a campaign characterized by maneuver, rather than large scale battles, highlights five important insights into operational warfighting. These insights include the translation of strategic guidance into an operational plan, offensive and defensive operational planning, the importance of deception, the effects of sustainment on an operation, and the influence of leadership on the planning and conduct of a campaign.
