What happened in those camps was all too real.
My father had the misfortune to see some of them, as he was a professional soldier, so he stayed in the Army after the War and they had to clean them up….he told my brother about some of it, but would never speak of it willingly….I never heard him say a word…..but apparently the atmosphere in them was bone chilling.
So anyone who denies their existence, is a cretin.
