Battery F. — Capts., R. B. Hampton, Nathaniel Irish, Edward R. Geary. Battery F was recruited at Pittsburg and mustered into the service of the United States at Williamsport, Md., Dec. 7, 1861, for three years. It joined Gen. Banks' army on the upper Potomac, participated in the action at Dam No. 5 in December and at Hancock, Md. early in Jan., 1862. In the repeated skirmishes between the forces of Gen. Banks and Stonewall Jackson in April, 1862, the battery was actively employed, but after the closing engagement at Winchester was stationed at Front Royal for three months and was not again in active service until late in August. With Gen. Pope's army, it participated in the fierce struggles of Bull Run and Chantilly and in the minor engagements preceding them. Its guns boomed at South mountain and Antietam, after which it was posted at Harper's Ferry with the 12th corps. At Charlestown in November and Winchester the following month the battery was active, but it arrived too late for a share in the battle at Fredericksburg. Winter quarters were established at Acquia creek. In the battle at Chancellorsville the command played an important part and on the last day of the fight Capt. Hampton was killed. On account of the heavy losses sustained the battery was consolidated with Battery C early in June and the two batteries were united during the remainder of the year. In the spring of 1864, a number of recruits was received sufficiently large to enable both batteries to become independent organizations. At Camp Barry, Washington, Battery F was refitted and became a part of the defenses of the city until ordered to Harper's Ferry on July 4 and remained in that vicinity until April, 1865. The original members who had not reenlisted, were mustered out at Maryland heights at the end of the year 1864, and the veterans and recruits returned to Washington in April, 1865, where they were mustered out June 26, 1865.
