ten o'clock
For three days and nights we were on the line at Hagerstown , skirmishing every day . Captain Shooter of the First now commanded the battalion . We were told that the Potomac was at a high stage , and that we must wait until a pontoon bridge could be laid . At ten o'clock on the night of the 13th the sharp-shooters received orders to hold their line at all hazards until dawn ; then to retire . The division was withdrawing and depended upon us to prevent the advance of the enemy . Rain fell all night . We were wet to the skin and almost exhausted through hunger , fatigue , and watching .
