town of Old Millersburg and beyond it to “Liberty Gap,” one of the several narrow defiles through the rough hills north of the Duck River. The division was preceded by five companies of mounted infantry, immediately behind which General Johnson and staff and myself followed. Nothing was seen or heard of the enemy until we approached the Gap in the afternoon, which the mounted infantry found strongly guarded by rebels. A lively skirmish ensued, and, the ground being unfavorable for a cavalry attack, the General ordered the leading brigade under General Willich to clear the way. The latter had his command ready for an advance in a short time, and moved forward with a strong line of skirmishers and supporting companies in advance, and one regiment on the right and another on the left of the road, with two regiments and a battery in reserve. The rebel skirmishers fell back before us upon their supports on the high hills forming the entrance to the Gap.

Their camps were also captured. We lost a small number in killed and wounded. Our troops displayed a good deal of dash.

It quickly made the roads almost impassable, and the consequent obstruction of the movements of the army eventually prevented the full success of Rosecrans's strategy.
