On August 12, 1862, 2.7 miles north of here, Confederate General John Hunt Morgan and his raiders, aided by citizens of Gallatin, demolished the Big South Tunnel on the Louisville & Nashville Railroad by crashing a locomotive into a barrier of timbers. The resulting explosion, fires, and collapse of the tunnel cut off United States Army supply lines to Nashville for 98 days.
