I grew up in Chantilly. My buddy lived in Centerville and there was and old stone bridge that dated back to the Civil War near his house (20 years ago). And what I believe used to be an old mill foundation.
It may have been hunted already but, there were troop movements through the area by both sides.
Find where "Cub Run" runs under Old Centerville Highway (runs across the old stone bridge) on a map and the mill foundation is about a third of a mile downstream.
