From the first of two markers for Early’s Brigade on the Antietam battlefield:
September 16-17, 1862 No.1.
On the night of the 16th, Early’s Brigade bivouacked in the farm lane on the left of Jackson’s Division and in the Dunkard Church woods, between this point and the Church. At dawn of the 17th, the Brigade moved nearly a mile northwest to support Stuart’s Cavalry Division and some Batteries of Artillery. The Brigade was on this duty about an hour when, leaving the 13th Virginia Infantry with Stuart, it returned and formed line on the plateau east of this, perpendicular to the Hagerstown Pike and, advancing in a northerly direction, as a support to Jackson’s right, participated in a sanguinary engagement with the right of the First Army Corps, which was obliged to retire, then moved to the south along the west edge of the West Woods, and engaged the enemy near the Dunkard Church.

Then, wheeling to the left, supported by the Brigades of Semmes, Anderson and Barksdale, and portions of Jackson’s Division, struck the flank of Sedgwick’s Division and forced it to retire from the field. The Brigade was then reformed and withdrawn to the position occupied by it in the morning and, later in the day, moved to the northern part of the West Woods, where it remained until the night of the 18th, when it recrossed the Potomac
