under the command of General Tyler, and at about 2 o'clock in the morning of July 21, our brigade leading the column, our battery was preceded by the First and Second Ohio Volunteers and the Second New York Volunteers in the above-mentioned order. We arrived in view of the enemy's position about 5 a.m., and immediately opened fire with the 30-pounder rifled gun attached to our battery, under the immediate command of Lieutenant Hains, U. S. Army. This fire not being responded to, it was soon discontinued, and our brigade was ordered to take up a position in order of battle to the right and left of the main road, our battery being placed in the skirts of the woods on the right, with a hill immediately in our rear. The ground in front was entirely open, extending to the creek, on the farther side of which the enemy had constructed an abatis. Three regiments of volunteers were placed near us to support our battery. We then awaited the advance of the columns under Colonels Hunter and Heintzelman, who were to attack the enemy in flank. These troops advanced into position about 9 a.m., and immediately opened the attack, which was continued with great warmth on both sides. Several regiments from General Tyler's division being ordered to cross the creek to their support, one of these regiments attempted to cross the open ground in front of our division, when a battery of the enemy opened fire upon them. Their regiment was instantly dispersed in all directions. We replied to this fire so successfully that in a short time the battery was completely silenced, and, from the accounts of persons who afterwards visited their position, we found that only some ten or twelve of their men remained unhurt.

The section under my command, being composed of one 6-pounder gun and one 12-pounder howitzer, made use of shell, spherical case, and solid shot, ending with a few rounds of canister. Our supports in the mean time had disappeared, and from this time no regular support was sent to us. Without using our field guns for some time we continued the fire with the 30-pounder at intervals. In the afternoon, probably about 2 o'clock, we were ordered to a new position to counterbatter the enemy's batteries, which were at such a distance that they could not be reached by our guns. We were here exposed to a most galling fire without being able to reply with success. The section commanded by Lieutenant Wilson having been ordered to a new position, and being actively engaged, I was ordered to place my section in a position to be designated by a captain of the Massachusetts volunteers, where, accordant to his statement, the ranks of the enemy could be much damaged by my fire. Upon advancing down the road for a quarter of a mile, under the fire of two of the enemy's batteries, this place was pointed out by the captain, but not liking the position, I considered it advisable to halt my sanction, and proceed alone to examine the ground. On examination, I found that I should be directly under the fire of two batteries, without any support, and where, to obtain an elevation necessary to throw projectiles three hundred yards, it would be necessary to sink the trails of our carriages in the ground. In addition to this, there was nothing to use artillery against, and no troops whatever to support us. Taking these circumstances into consideration, I did not think that I should be justified in placing my guns in such a position, and consequently returned to my starting point.

Shortly after this our battery moved to the rear into the woods, and there remained in the road, the battery being in column of pieces. We remained in this position for some little time, when an order was given to move still farther to the rear. On emerging from the woods, we encountered a charge of cavalry. When my section was made aware of
