Frank Moore, ed. Vol. 4. New York: G. P. Putnam, 1863
The guerrillas in Western Virginia are still troublesome. Two secessionists belonging on the Valley River, in the upper end of Marion County, were shot this day by a detachment of Capt. Showalter's company. Their names were Sack Barker and Levi Ashcraft. A band of guerrillas (supposed to belong to the same gang from which Riblet and Conway were captured) had taken prisoners a couple of young men, soldiers in Capt. Showalter's company, and their comrades in rescuing them captured the two guerrillas above named, and killed them on their attempting to escape. This took place near Texas, on the Baltimore and Ohio Railroad.
