War has a feminine face...

I'm sharing what I heard, unfortunately, I don't remember which documentary film about World War II it was. And I didn't hear it from my relatives, but from people who fought. I was shocked when I learned this. I'm sure I didn't make it up.

A reference to "I don't remember what, I don't remember where" is unlikely to be convincing. Moreover, you previously referred to the film "Come and See," which, firstly, is not a documentary but a fictional film, and secondly, does not contain anything of what you are saying, as badping already pointed out in this thread.
"Heard from people who fought" - are these Nazis? Or did Russians tell you that they burned their own civilians? You have some interesting acquaintances...
