In the meantime, the enemy guns across the river opened on us and the shells were flying about us in lively fashion. It was rather a sudden transition from peace to war, but we had been at this business before; the sound of the shells was not unfamiliar--so we were not unduly disturbed. We quickly got the guns loaded, and opened on that Infantry, advancing up the hill. We worked rapidly, for the case was urgent, and we made it as lively for those fellows as we possibly could. In a few minutes a pretty neat little battle was making the welkin ring. The sound of our guns crashing over the country behind us made our people, in the camp back there, sit up and take notice. In a few minutes we heard the sound of a horse's feet running at full speed, and Gen. Dick Ewell, commanding the Second Corps, came dashing up much excited. As he drew near the guns he yelled out, "What on earth is the matter here?" When he got far enough up the hill to look over the crest, he saw the enemy advancing from the river, "Aha, I see," he exclaimed. Then he galloped up to us and shouted, "Boys, keep them back ten minutes and I'll have men enough here to eat them up--without salt!" So saying, he whirled his horse, and tore off back down the road. In a few minutes we heard the tap of a drum and the relieving Brigade, which had been delayed, came up at a rapid double quick, and deployed to the right of our guns; they had heard the sound of our firing and struck a trot. A few minutes more, and the Brigade that had left, that morning, came rushing up and deployed to our left. They had heard our guns and halted and came back to see what was up. With a whoop and a yell, those two Brigades went at the enemy who had been halted by our fire. In a short time said enemy changed their minds about wanting to stay on our side, and went back over the river a good deal faster than they came. They left some prisoners and about 300 dead and wounded--for us to remember them by. The battle ceased, the picket line was restored along the river bank, and all was quiet again. Bob McIntosh was more put out by all this business than anybody else--it had interrupted his hair cut. When we first got the guns into action, everybody was too busy to notice Bob's head. After we got settled down to work, I caught sight of that half-shaved head and it was the funniest object you ever saw. Bob was No. 1 at his gun, which was next to mine, and had to swab and ram the gun. This necessitated his constantly turning from side to side, displaying first this, and then the other side of his head. One side was perfectly white and bare; the other side covered by a mop of kinky, jet black hair; but when you caught sight of his front elevation, the effect was indescribable. While Bob was unconsciously making this absurd exhibition, it was too much to stand, even in a fight. I said to the boys around my gun, "Look at Bob." They looked and they could hardly work the gun for laughing.
