"During the 2nd of July, a detachment of Berdan's sharpshooters, using very heavy, long-range telescope rifles, with a sort of tripod rest, were placed on our main line with instructions to stop this annoyance. The method adopted was somewhat peculiar. The enemy's sharpshooters soon discovered, not only that we were using rifles that had sufficient range, but also that they were being used with remarkable precision. With a field-glass it was easy to observe the effect of this rifle practice. Several men were seen to fall at the openings in the barn, and the enemy's sharpshooters became more and more cautious. At the flash of a rifle on our line they would instantly disappear, and upon the ball passing through the opening as instantly reappear, ready to try a shot or fall back again if a second rifle flashed on our line. To meet these tactics, new methods were adopted by the telescopic riflemen; they formed themselves into squads or partnerships of three, and when the three were ready with correct aim, number one would fire; the enemy would instantly retire from the two openings; then counting 'one, two, three,' the remaining two partners would fire simultaneously, each at his appointed opening; the ball from number one passing through the opening, the enemy immediately reappeared, too late to see the flash of the second rifles, yet in time to receive their bullets. Alas! how little we thought human life was the stake for which this game was being played."
