This thesis is a historical analysis of Major General James Negley and his division during the Battle of Chickamauga. An examination of Negley, his actions, his major subordinate commanders, and the regiments of the division was conducted to provide a base with which to evaluate the principals during the Chickamauga Campaign of 1863. On 19 September, the division fought well as, and served to arrest a Confederate penetration of the Federal lines. The division was piecemealed into the fight on 20 September by brigade, and regiments. Negley ended up commanding fifty Federal artillery pieces on Snodgrass Hill and withdrew them to support the Union collapse upon Chattanooga. Negley was relieved after the battle, and charged with removing the artillery prematurely. He was acquitted of all charges during a subsequent court of inquiry; however, he never received another command.
The relief of Negley tarnished an otherwise solid performance by the division during the two day battle. This study analyzes Negley and his division during the Battle of Chickamauga and draws conclusions using the battle command competencies as a framework: seeing the enemy, seeing the terrain, knowing yourself, visualizing the battle, and seeing into the future.
