White's Ford was an important ford over the Potomac River during the American Civil War. It was used in many major actions, including the crossing into Maryland of the Confederate army prior to the Maryland Campaign and Confederate Major General J.E.B. Stuart's ride around Union Major General George B. McClellan on October 10, 1862, when he used the ford to cross into Loudoun County, Virginia. It is located a few miles above present-day White's Ferry.
