Battle of Missionary Ridge

The Third Battle of Chattanooga (popularly known as The Battle of Chattanooga, and including the Battle of Lookout Mountain and the Battle of Missionary Ridge) was fought from November 23 to November 25 1863, in the American Civil War. By defeating the Confederate forces of General Braxton Bragg, Union Army Major General Ulysses S. Grant eliminated the last Confederate control of Tennessee and opened the door to an invasion of the Deep South that led to the Atlanta Campaign of 1864.
