From the monument to the 5th, 7th and 66th Ohio Infantry Regiments:

These three regiments became engaged about 7:30 A.M., September 17, 1862, advanced and drove the enemy from the woods near the Dunkard Church and were in action until 1:30 P.M. Their combined loss was 17 men killed, 4 officers and 87 men wounded, 2 men missing, total 110.

From the first of two War Department markers on Tyndale’s Brigade on the Antietam battlefield:

Tyndale’s Brigade, on the right of the Division, reached this point about 8 A. M., relieved a portion of Crawford’s Brigade, and engaged the Confederate Infantry in the East Woods.

After a short and sharp contest, the enemy gave way and the Brigade, obliquing to the left, crossed the Smoketown Road, entered the fields to the right of Mumma’s burning buildings, and took position behind the ridge opposite the Dunkard Church.

From the second of two War Department markers on Tyndale’s Brigade on the Antietam battlefield:

Tyndale’s Brigade, after the right flank of the enemy had been turned, pursued through the East Woods, crossed to the south side of the Smoketown Road and passing to the right of Mumma’s burned out buildings, halted behind the ridge a few yards east of this point, where, with the assistance of Monroe’s and Tompkins’ Rhode Island Batteries, it repulsed several assaults of the enemy.

About 10:30 A. M. the Brigade crossed the road and entered the woods on the right of the Dunkard Church. Joined on the right by the 13th New Jersey Infantry of Williams Division, it remained in this position until noon when it was compelled to retire to the East Woods.

From Lieutenant Colonel Powell’s Official Report on the 66th Ohio in the battle:

The regiment moved to the field of battle in column, in company with the Fifth and Seventh Ohio Volunteers (infantry), and Twenty-eighth Pennsylvania Volunteers, composing the First Brigade, under command of Lieutenant Colonel Hector Tyndale, of the Twenty-eighth Pennsylvania. Moving in front of a piece of woods in which the enemy were in force, and under whose fire we were placed, having 2 wounded while we were in column, I immediately deployed my regiment, and two high fences were a serious obstacle to my deploying to the left. I formed in line of battle, moving to the right. I observed that the Seventh Ohio had formed line in a similar manner, and I immediately attached my regiment on the left of the Seventh Ohio, and together we moved toward the right of the line that the Twenty-eighth Pennsylvania were forming, which brought us immediately in front of a line of the enemy drawn up along a fence, in the edge of a corn-field. We immediately opened fire upon the enemy, who soon broke. We advanced, firing, in connection with the other regiments composing the First Brigade.

The retreat of this line of the enemy soon became a rout. My regiment took a number of prisoners, who were sent to the rear. The regiment moved rapidly forward and formed, with the rest of the brigade, under shelter of a small knoll, directly in front of the church on the Sharpsburg road. This regiment assisted in repulsing the several attacks made by the enemy to drive us from this position, and in their last attack I was wounded by a musket-shot along the cheek and neck, which disabled me from remaining on the field the rest of the day.

From the report of the acting adjutant of the regiment, we went into action 120 strong, and this small force acted as efficiently as it was possible for it to do. I had but two commissioned officers with me in the action, Lieutenants Smith and Yagel, both of whom escaped unhurt.
