1. Report of Captain Thomas S. Dunn
A segment from the Official Reports, Series I, Volume XXVII/1 (S#43), Report number 208, pages 640-1.
The First Brigade, Second Division, Fifth Army Corps, of which the battalion
The battalion remained in this position until I received an order to move by the right flank a distance equal to my front. During the execution of this order, the troops on our right having fallen back in some disorder, the enemy rapidly advancing, I received from General Ayres, commanding division, the order to face by the rear rank and march to the position first occupied. The battalion marched to the rear in quick time under a galling fire, in good order, until I received an order to double-quick. This order was obeyed until the battalion reached a stone wall about midway in the valley. I then ordered the left wing to about-face and fire. They delivered their fire, and again joined the right wing, moving to the rear. The battalion was halted on the brow of the hill and faced to the front. The fire gradually slackened as night approached.
