A large portion of the rebel troops were now closing in on Cheat Mountain, when detachments of the Fourteenth Indiana, and Twenty-fourth and Twenty-fifth Ohio, numbering in all about three hundred, held them in check. Affairs rested in this condition till dark. Determined to force a communication between the detached portions of his command, General Reynolds ordered the Thirteenth Indiana, under Colonel Sullivan, to cut their way, if necessary, by the mail road, and the greater part of the Third Ohio and Second Virginia, under Colonels Manon and Moss, respectively, to do the same by the path; the two commands starting at three o’clock, A. M. on the 13th, the former from Cheat Mountain Pass, and the latter from Elk Water, so as to fall upon the enemy simultaneously, if possible. Early on the 13th, the small force of about three hundred from the summit, engaged the enemy with such effect, that notwithstanding his great superiority in numbers, he retired in great disorder, leaving large quantities of clothing and equipments on the ground. The relieving forces failing to encounter the enemy, marched to the summit, secured the provision train, and reopened the communication. While these events were proceeding on the mountain, General Lee advanced on Elk Water, apparently for a final attack. A rifled Parrot gun from Loomis’ battery was run to the front about three-quarters of a mile, and after a few shots, which told with fine effect on their ranks, they retreated to a place beyond its range. On the 14th, the enemy was again in position in front of Elk Water, but were repulsed by the gallant Fifteenth Indiana, who held their ground and fired with the most telling effect. The enemy also made an effort to reach the pass, but they were again repulsed, and withdrew to a point some ten miles distant. On the 15th, the rebels appeared again in much stronger force than before, and attempted a flank movement by the left, but they were driven back and compelled to retire from the field by the vigilant and heroic garrison on the summit. One hundred of the enemy were killed and wounded, and about twenty were taken prisoners. The Federal forces lost nine killed, and about sixty prisoners. Lieutenant Junod, of the Fourteenth Indiana, was among the killed, and Captain James Bense, and Lieutenants Gillman and Shaffer, of the Ohio Sixth, and Lieutenant Merrill, of the Engineers wounded. One of the most important incidents of this engagement was the death of Colonel John A. Washington, of the rebel army, aid-de-camp to General Lee. ENGAGEMENT AT CHAPMANSVILLE. A brilliant affair took place at Chapmansville, Logan county, Virginia, on the 25th of September, when a body of the enemy under Colonel Davis, numbering about five hundred, was defeated and driven from behind their breastworks by five hundred and fifty men of the Thirty-fourth Ohio, under Colonel Piatt.
