When the Civil War erupted, celebration erupted in Trout's Hill and the American flag was replaced by the Virginia flag. In late August 1861, a three-day skirmish raged in the streets of Trout's Hill as Union troops from Ceredo tried to obtain the county records. The Union men camped in the courthouse, and local Rebels tried to force them out. Having accomplished their goal, the Yankees returned to Ceredo. Several more Union raids were launched against Trout's Hill During the war.
