1st Battalion New York Light Artillery, Battery A

From Colonel Hays' Report:

Early on the morning of the 16th instant I placed Captains Taft's and Langner's and Lieutenant Von Kleiser's and Lieutenant Wever's batteries of 20-pounder Parrott guns in position on a hill in rear of and near the bridge over the Antietam Creek, the position being in rear of and about the center of our line of battle. Soon after getting into position the enemy opened upon us a heavy fire from several guns. The firing was returned, and kept up briskly until the enemy stopped firing and withdrew his guns.

... From early in the morning of the 17th, until late in the afternoon, Captains Taft's and Langner's, Lieutenants Von Kleiser's, Wever's, and Hazlett's batteries fired at the enemy's batteries and troops whenever and wherever it could be done without risk to our own troops. These batteries were well served and the fire very effective.
