It is hurtful to see. I met some Poles in NYC in the 70’s that lost their whole family except for themselves and 2 daughters. They hid in caves and Paul stole food at night. The stories were very frightening.
Such a tragic sight caused me to read and pay attention to the subject. They were revolting times, possibly the most written about than other mass murders and inhumane treatment.
Reading about it gives one understanding of why we should learn history and how mankind can revert to heinous cruelty.
