|The "Fighting Bishop"|
Gen. Leonidas Polk
But on today's date in 1862, Gen. Polk learned that in addition to a Federal column moving east toward Frankfort, 3 columns of Federals were also marching on 3 separate roads southeast from Louisville toward his army's position at Bardstown. Although ordered to move the army to Frankfort, after considering the approach of McCook’s, Gilbert’s, and Crittenden’s Federal corps toward Bardstown, Polk instead marched the army toward Harrodsburg via Perryville.
In the meantime, Union Gen. Don Carlos Buell assumed command over the forces at Louisville. On today's date, he marched out of Louisville with 60,000 troops. Buell sent a small force to Frankfort to deceive Bragg as to his army's direction and location. Bragg was outsmarted. On October 4, the small Federal force attacked Frankfort just as Bragg was installing a new Confederate governor there. Bragg was forced to make a hasty retreat to rejoin his army, now on the move to Bardstown, thinking the entire Federal force was headed for Frankfort.
