Three Union armies attacked the Army of Tennessee atop Missionary Ridge, east of downtown Chattanooga. Patrick Cleburne stopped William Tecumseh Sherman from the north, although outnumbered 10 to 1. Joe Hooker was seriously delayed by burnt bridges and failed to hit the southern end of Bragg's line near Rossville, Georgia. Thomas' Army of the Cumberland struck the center, breaking Bragg's line and forcing a retreat. Sheridan, ordered to pursue, was stopped dead in his tracks by William Hardee's rear guard action.
Major General John Breckinridge [CS], using a ragtag force that included VMI cadets attacked Franz Sigel's [US] line near the north fork of the Shenandoah River. Sigel eventually withdrew to Strasburg.
Jubal Early's [CS] move to the Shenandoah Valley is blocked by George Crook [US], at least for a while. After a violent assault on the Union left by John Breckinridge the federal line broke and pulled back to Harpers Ferry
