Union Tactical Maneuvers at Chattanooga
Union commanders coordinated river landings and railroad logistics to shift troops rapidly around Confederate flanks. Securing high ground west of the Tennessee River allowed Union artillery to dominate key approaches into Chattanooga.
On Orchard Knob and the slopes of Missionary Ridge, Federal units staged careful advances that compressed Confederate defensive arcs and forced difficult repositioning under fire.
Confederate Defensive Strategy and Terrain Use
Confederate forces anchored their defense on Lookout Mountain and Missionary Ridge, attempting to use natural elevation to offset Union numerical superiority. Artillery placements on these ridges aimed to break Union formations before they could reach assault range.
Gaps between Lookout Mountain and Missionary Ridge, notably at Wauhatchie, created vulnerabilities that Union night maneuvers exploited to extend pressure along the Confederate rear.
Key Battles Within the Chattanooga Campaign

Geography and Its Influence on the Battle
The Tennessee River curved around Chattanooga, creating narrow corridors where Union forces could concentrate. Confederate observers on high ground had clear lines of sight but also funneled attackers into predictable paths.
Valleys and ridges dictated columns of march, sightlines for artillery, and the timing of assaults, making terrain a decisive factor rather than sheer troop numbers alone.
