Rebel communication problems caused a delay in the opening of the second day of fighting. Union troops continued a complicate movement towards Chattanooga. During an attack by James Longstreet [CS] an opening at the Brotherton Cabin was exploited by John Bell Hood [CS], routing the Union Army. Rosecrans [US], McCook [US] and Crittenden [US] fled the field of battle. George Thomas [US] formed a weak line around Snodgrass Hill while maintaining a stronger line along Battleline Road (present-day name). Gordon Granger [US] advanced without orders and resupplied and reinforced the beleaguered Union Army, which withstood repeated Confederate attacks. Chickamauga
