As I heard it related from an old guy in VA, you could still find the equipment of the soldiers scattered around the old battlefields, mostly in woods, in the 50’s and 60’s.
When I was a kid there, I found wagon wheel rims, spokes and other such debris in the N. VA woods.
Not far from where I grew up (inside the then building beltway) was, in the woods, the brick ruins of an old mill that had been destroyed during war. We played there a bunch.
