Roman battlefield found deep inside Germany

[jkaler48]

"-The fact that the weapons were left "on site" still riddles the excavators and an international circle of scientists/scholars will be constituted to discuss the "open" questions"

Either side would have "policed" the battlefield after a battle. The Romans
to keep weapons and metal to make weapons from the enemy and for salvage purposes - The "Barbarians" to reuse the weapons and metal.
Perhaps the ground was marshy, muddy or partly flooded during or shortly after the battle causing so many items to be not recovered by either side.
It may be that something like that could be concluded from detailed study of the soils that hasn't been completed yet. REVISION: OK looked at the photos of the find site on the side of a hill! Not marshy or flooded. Still maybe muddy. Maybe a mud slide buried the items.
