The Battle of Missionary Ridge was fought on November 25, 1863, as part of the Chattanooga Campaign of the American Civil War. Following the Union victory in the Battle of Lookout Mountain on November 24, Union forces in the Military Division of the Mississippi under Maj. Gen. Ulysses S. Grant assaulted Missionary Ridge and defeated the Confederate Army of Tennessee, commanded by Gen. Braxton Bragg, forcing it to retreat to Georgia.
In the morning, elements of the Union Army of the Tennessee commanded by Maj. Gen. William Tecumseh Sherman attempted to capture the northern end of Missionary Ridge, Tunnel Hill, but were stopped by fierce resistance from the Confederate divisions of Maj. Gen. Patrick Cleburne, William H.T. Walker, and Carter L. Stevenson. In the afternoon, Grant was concerned that Bragg was reinforcing his right flank at Sherman's expense. He ordered the Army of the Cumberland, commanded by Maj. Gen. George Henry Thomas, to move forward and seize the Confederate line of rifle pits on the valley floor, and stop there to await further orders.
