“Cliffton”
On this location Maj. R. G. Watson and his daughter Mary, both Confederate agents, lived and carried on a direct mail and slave route between the North and the South during the entire Civil War. Because of the unobstructed view from these cliffs, this was an ideal location. Maj. Watson would meet the boat while Mary would watch from an upstairs window and signal if it was unsafe by placing a black flag in the window.
Within a short distance from this point John Wilkes Booth, Abraham Lincoln's assassin crossed the Potomac in his historic flight.
Marker is on Overlook Circle.
