But i think it's just artistically exaggeration
Maybe, but mind that in 200 years the ground was probably levelled a lot by natural erosion or man's action....
There were first the burial of thousands of men and horses, peasants searching what they can catch, (or cultivating on naturally fertilized ground
), then curiosity, collectors, archeologists -amateurs or not- and probably some heavy circulation
in WWII !
This is why I look seriously at paintings and drawings made on the spot a short time after the events and also memoirs of fighting men or witnesses.
If you have a look at Waterloo's battlefield sites, you will find how it was almost totally remodelled ( mostly for erection of Wellington's atrocious memory
) - to the point that many features are completely out of significance....This is explained by British historian themselves
One of the best preserved battlesite I know is Gettysburgh, but only because it was protected immediately and benefits of regular cares ( up to keeping the vegetation as close as possible of the time of battle) so, you can look at the Panorama and find many points in the landscape.
Now, this is not to discourage you, as you did a very good job and much work for our pleasure of warGaming
