We pushed forward and got the pieces in position between Ricketts's and Griffin's batteries, but before a single shot could be fired, the fatal mistake of the day occurred, the mistake of supposing a rebel command to be a portion of our own forces. Thick and fast their bullets came in upon us, and they were fast approaching in their charge, when with almost superhuman energy, and with a rapidity that I never saw excelled and I think I never saw equaled, our cannoneers limbered to the rear and we withdrew with a loss in material of only a caisson, the pole of which was broken in the endeavor to turn on the side hill, and there was no time then to stop for repairs. Here private Bubb (Frederick) lost his life, and private Vose (Warren L.) was wounded and taken prisoner. A bullet went through my cap and ploughed a little furrow in my scalp. Jumping from my horse to assist Sergeant Wilcox (G. Holmes) in limbering his piece, the animal dashed off frightened by the confusion, and I was obliged to ride to the rear on the stock of the gun carriage. Arriving on the northerly side of the turnpike, we were joined by Captain Reynolds near the "Doogan" House, and shortly after by Lieutenant Weeden. Captain Reynolds said that he had just seen Arnold, (Captain of the regular artillery) who had lost his battery. I hastened with the two guns off to the left, to the position that we first occupied in the morning, and, going into battery, commenced firing. The men worked steadier and cooler than they had at any time during the day. All at once there emerged from the timber in our front, a regiment or brigade of the enemy, evidently preparing for a charge upon us, and simultaneously came an order, from Captain Reynolds, I believe, to limber to the rear. I could not resist the temptation, in spite of the order, to give them one more shot before parting, and I directed the left piece to be loaded with canister. As the piece was fired, the enemy, apparently, was just ready to move forward on their charge. It appeared to me that a gap of full twenty feet was made in their line, which completely staggered them. This, I think, was the last shot fired on the field that day. The first one was fired by Sergeant Dwight.
