As soon as the firing commenced the troops in advance, with the exception of a small guard, were ordered back to the scene of action on double-quick, which order was obeyed with alacrity. Just before the advance guard reached the center the rebels showed themselves in force in a field on the rear of our right wing. The column was halted, faced by the rear rank, and a volley fired, which drove the rebels again to the wood. Shortly, however, they rallied, keeping farther from us, and attempted to attack and stampede the head of the train. Companies A, F, and D, First Lieutenant McClure and Captains May and Morrison commanding, were sent again forward with rapidity to frustrate the rebel designs, which they accomplished satisfactorily.
