Army of the Cumberland and the Battle of Stone's River

The Army of the Cumberland was one of the principal Union armies in the Western Theater during the American Civil War. It was originally known as the Army of the Ohio. The army's first significant combat under the Cumberland name was at the Battle of Stones River which ended in Union victory after the Confederate army's withdrawal on January 3, largely due to a series of tactical miscalculations by Confederate General Braxton Bragg.
