Battery C. — Capt., James Thompson. Battery C was mustered in at Pittsburg Nov. 6, 1861, for three years, and was attached to the 2nd division, 3d corps. It shared in the battle of Cedar mountain, the skirmishes following near the Rappahannock, the second battle of Bull Run, Chantilly, South mountain, and Antietam. It was then transferred to the 2nd division, 1st corps, with which it participated in the battle of Fredericksburg and in the Chancellorsville movement in the spring of 1863. In all these battles the battery suffered heavy loss and owing to the depleted numbers of the command and of Battery F, the two were united under Capt. Thompson and assigned to McGilvray's brigade, artillery reserves, Army of the Potomac. At Gettysburg, the losses were heavy but the work of the battery was effective and continuous. Batteries C and F, as well as individual members of the commands, were highly complimented for their gallantry. The batteries continued to see much active and varied service and their guns were heard at Mitchell's ford, Mine run, and Morton's ford. Early in 1864, the original members were mustered out ; but a large number of the members reenlisted and the two batteries were continued in the field as veteran organizations. Winter quarters were established at Brandy Station and in the spring the batteries were ordered to Washington for refitting and equipment. They formed part of the defenses of Washington, with the exception of a short time on duty at Harper's Ferry, until the expiration of their term of service. Battery C was mustered out on June 30, 1865, at Pittsburg.
