Several American Civil War engagements occurred in and around the Cumberland Gap and are known as the Battle of the Cumberland Gap. In June 1862, Union Army General George W. Morgan captured the gap for the Union. In September of that year, Confederate States Army forces under Edmund Kirby Smith occupied the gap during General Braxton Bragg's Kentucky Invasion. The following year, in a bloodless engagement in September 1863, Union Army troops under General Ambrose Burnside forced the surrender of 2,300 Confederates defending the gap, gaining Union control of the gap for the remainder of the war.
