Barnett's Battery I, 2nd Illinois Light Artillery, armed with 2 Napoleons, 2 James Rifles, and 2 Parrots, served with Colonel Daniel McCook's Brigade in Granger's Reserve Corps on September 20th, 1863, under Captain Charles M. Barnett. About 1 p.m., the battery moved with its brigade under orders from the vicinity of McAfee's Church, two and one-half miles northeast of this point, to the battlefield, and while moving rapidly in column through burning woods, it was fired on by the enemy and compelled to move by the right flank into the open field in front while the enemy shelled vigorously. About 2 p.m., after the fire in the burning leaves and grass was extinguished, the battery took position on the crest of the ridge in rear of this ground, supported by the brigade, and opened on the enemy, firing at intervals until 6 p.m. It aided General Turchin in his advance by shelling the enemy from his front until he secured shelter and reformed behind McCook's Brigade. The battery closed the action with two successive six-gun discharges and soon after dark retired under orders with its brigade to Rossville.
