Battery I, 1st U.S. Artillery 

Lieut. Geo. A. Woodruff, U.S.A., Commanding.

(September 17, 1862.)

Between 9 and 10 A.M., Battery I, 1st Artillery, advancing by the Smoketown Road, passed through the East Woods to the assistance of the Infantry of Sedgwick’s Division, then engaged in the West Woods. The Battery went into position about 380 yards north, 62° west of this point, opening fire at once, with canister, and checking the advance of the Confederates from the West Woods. A movement of the enemy on its left, from the woods around the Dunkard Church, compelled the Battery to retire to this point, its left gun on the road, where it again went into action. It remained in this position until about noon, when it was relieved by Batteries A and C (consolidated), 4th U.S. Artillery, and withdrawn. At 5 P.M., after replenishing ammunition, the Battery took position on the ground overlooking the Sunken Road where Richardson’s Division had been engaged, and remained until 2 P.M. of the 18th.
