On October 4, 1862, Terry's Texas Rangers, CSA, under the command of Col. John Wharton, were posted north of Bardstown at Fairgrounds crossroads on the Louisville Pike, to intercept units of Buell's Union Army of the Ohio, moving south. Bragg's CSA Army of Mississippi was withdrawing from Bardstown, moving east toward Harrodsburg.
The Ranger's rear-guard action found itself confronted with far superior numbers. Wharton ordered the Rangers into columns and gave the bugle command to charge. The bold action broke the Union lines, scattering the cavalry troopers and infantry into disarray. This was a victory for the Texas Rangers who fought next at Battle of Perryville.
