On the 4th of October, when 6 or 7 miles in front of Bardstown, vigorously resisting the advance of the enemy, he received information that he had passed by his right flank and was already in his rear with a heavy force of cavalry near Bardstown, thus completely cutting him off from Bragg's army. This was entirely unexpected, as he supposed his right was guarded by Gen. Wheeler (then colonel) with a brigade of cavalry. Nothing but the prompest, most courageous and skilled conduct could extricate the command from his dangerous and critical position. He at once resolved upon his course and in five minutes was going down the Bardstown pike at full gallop; the Texas Rangers in front, led by Maj. Harrison, to execute his fearless plan. The enemy was advantageously posted on each side of the pike and in heavy column immediately upon it. Putting himself at the head of the Rangers and by the side of Maj. Harrison, unchecked by the heavy volleys which the enemy poured in upon them, he heroically dashed through them, scattering them like chaff; breaking to atoms their well formed lines, and columns; scattered them in the wildest confusion and dismay, driving them from their chosen position--a routed and panic stricken herd. Without the loss of a man killed, he killed and captured over 160 of their select cavalry which had been sent around especially to capture him and his brigade. This gallant and most brilliant exploit gained for him an enviable reputation with the entire army and called forth a special order from Gen. Polk, who was commanding, complimentary in the highest terms to himself and the Texas Rangers.
