(September 17, 1862.)
Anderson's Brigade was withdrawn from the Boonsboro Pike at about 7:30 A.M. and moved to a position in rear of the Dunkard Church.
It supported McLaws' Division in the attack on Sedgwick's Division, and was then moved to this point where, forming behind the stone fence, it engaged the enemy in Piper's Cornfield but, being enfiladed by the Federal Artillery, was soon obliged to retire in the direction of Sharpsburg. Between 2 and 3 P.M., with portions of other Brigades, it formed a line extending from Piper's Barn to the Hagerstown Pike and assisted in repulsing an attack of the enemy.
