I saw several plots of buried USSR soldiers and their monuments, while in Poland. They are being left to rot. I had commented on them as we passed them. The old polish saying,”We fought the Germans for revenge, the Russians for fun.” (I don’t remember the exact words but it was like that.)
I was surprised to learn there’s a fairly well maintained German cemetery in Normandy for the German soldiers that fell there.
