On the same day that the disastrous battle at Ball’s Bluff, Va., was fought, and also the successful engagement of Colonel Plummer’s command at Frederickton, Mo., a spirited fight was maintained by a small force of Federal troops in Kentucky. They were successful in resisting the attack of a large body of the enemy under General Zollicoffer, who had made advances into that State from Tennessee, by the Cumberland Gap. The engagement was unimportant when viewed in reference to the numbers engaged, or the loss of life, but its moral effects were significant. It was the first battle thus far that had taken place upon the soil of Kentucky, and it was bravely fought by her own loyal sons. To oppose the advance of the rebels, a single Kentucky regiment, under Colonel Garrard, was stationed at Rock-castle creek, at an encampment known by the name of “Wild Cat.” General Zollicoffer conceived the design of cutting off this isolated regiment, and for that purpose was moving rapidly forward with six regiments of infantry and one of cavalry, sacking the towns of Barboursville and Loudon in his progress. General Albin Schoepf, who commanded the Federal troops in this district, hearing of the advance of the rebel forces, dispatched the Thirty-third Indiana, Colonel J. Coburn, from the camp at Big Hill, nineteen miles south of Richmond, with instructions to occupy an eminence half a mile to the east of Camp Wild Cat, while directions were also given to the Fourteenth Ohio to proceed to the same place; and two regiments of Tennessee Federalists, then at Camp Dick Robinson, forty-four miles from the scene of action, hastened to participate in the expected fight, and marched the whole distance on the day of the 21st, arriving just after the last feint by the enemy. Colonel Woolford’s Kentucky cavalry had also arrived, and General Schoepf and staff reached the scene of action in the course of the day. At eight o’clock on the morning of the 21st, before the arrival of Colonel Coburn’s forces at the point designated, the advance of the enemy, with wild and exultant shouts, attacked Colonel Garrard’s camp, and anticipated an easy victory over an inferior force, much reduced by sickness. But the brave Kentuckians met them with an undaunted front, and poured into their ranks a deadly fire. Having been taught to despise the little band they were now attacking, the rebels advanced again gallantly to the assault, but the cool and determined resistance they met with soon put them to flight, and they retired discomfited, to await the arrival of the main body of their forces.
