Batteries A and C 4th U.S. Artillery.
Lieut. Evan Thomas, U.S.A., Commanding.
(September 17, 1862.)
Batteries A and C (consolidated), 4th U.S. Artillery (6 guns), relieved Battery I, 1st U.S. Artillery just north of this point and went into position, the left of the battery resting on this road, where it remained inactive until Greene's Division, Twelfth Corps was driven from the woods around the Dunkard Church, when the battery changed from to the left, opening fire with spherical case and canister upon the charging Confederates, who, by the aid of Irwin's Brigade and two regiments of Hancock's of the Sixth Corps, were repulsed. The Battery then resumed its original front and opened with solid shot upon the Confederate artillery in the woods around and north of the Dunkard Church. Late in the day it was relieved and moved to the high ground occupied by Richardson's Division in its assault upon the Confederates in the Sunken Lane and Piper's Cornfield, where it remained until the morning of the 18th.
