Company B served, through March 1863, independent of the battalion, mostly in West Virginia, western Maryland, and the northern part of the Shenandoah Valley. The company was present in action as South Branch Bridge, West Virginia (October 26, 1861) and at the Battle of Kernstown (March 22, 1862), and spent much of 1862 in the area of Romney, West Virginia, on duty as a scouting force. They were in action again at Grass Lick, West Virginia, on April 23, 1862, and at Wardensville, West Virginia, on May 7, 1862. The company regularly served along with Colonel Andrew Thomas McReynolds’ Cavalry [the 1st New York "Lincoln" Cavalry]. It joined General Jacob Dolson Cox’s Brigade in pursuit of J.E.B. Stuart, during his October 1862 raid into Pennsylvania. For the balance of the year, through early 1863, the company operated along the Chesapeake and Ohio Canal and around Martinsburg, West Virginia.
