May 15th. Rain. Rain. On picket, wondering why we do not get relieved. It is past time for the relief to show up. Lieutenant Kerr sends a detail to camp to learn the cause. Returned in a short time, reported the regiment had left for parts unknown. The Lieutenant called in the pickets to the reserve headquarters in the woods. Formed company and were ready for action as we marched out of the woods to the pike, expecting to meet the enemy’s scouts. Instead we met our own cavalry scouts who reported our regiment left in the night, going up the valley towards New Market. We started on after them, making a forced march, wet, tired, hungry, well used up. Some misunderstanding of orders was the cause of our being left on picket. It was a wonder to us that we did not meet the rebel cavalry and have a hot time, as they had been in this vicinity, scouting all around us. We were determined to put up a hot fight, had we met the enemy. Lieutenant Kerr kept urging us on, making a forced march up the pike. Duty having been so severe, and the lack of rations for the past few days, we were near used up. The last two miles of the march we ran, and joined the regiment as they were going into action, having made a march of sixteen miles with hardly a rest, and very little to eat.
Colonel Moore, Commander of our brigade, pushed our regiment and an Ohio regiment, with a section of a battery, two field guns, about six miles in advance of the main army, bringing on a general engagement. We could not hold the enemy in check as they advanced with a long line of battle. Our battery fell back. The Ohio regiment followed, when our commander, Lieutenant-colonel Peale, gave the command to our regiment, “By the right of companies, to the rear in column,” so we continued to march until we met the 34th Massachusetts Regiment, coming running up with a battery, taking a good position. The enemy was held in check, but for a short time. Sigel managed to get his main force in line, batteries posted, so the enemy was held in check. Our brigade suffered heavy loss. Some of the field pieces had to be abandoned as the horses had been killed and we were in too much mud to draw them away, or back to the main line. It looked to us like a case of mismanagement.
