The Fight at Waterford was a small skirmish during the American Civil War that took place in Waterford, Virginia on August 27, 1862 between the local partisan cavalry units of White's Rebels, fighting for the Confederates, and the Loudoun Rangers fighting for the Union. The Rebels surprised and routed the newly formed Loudoun Rangers in their camp at Waterford, capturing nearly the whole unit before subsequently paroling them, thus resulting in a Confederate victory. The action was the first significant partisan fighting in Loudoun County.
