It's painfully difficult to think of the horrors faced on a daily basis by those interned in concentration camps during WW2.
It's also gratifying to know there were people like Master Sgt. Roddie Edwards, Sir Nicholas George Winton, Oscar Schindler and I'm sure many others who did what they could to save lives. I saw a documentary where a young girl of 4-5 named Sara Reichman was saved by a good German family during the war. They lied and told neighbors she was a relative displaced by the war. When the war ended, relatives of the young girl located her but the German family regarded her as part of their family and didn't want to give her up but of course reluctantly let her go.
In the Documentary, Sara goes back to Niemodlin, Poland to visit with the Polish family that saved her from the Nazis.

There is also the story of Cantor Moshe Taube and his father Maximillian who were one of the lucky few to be included on " Schindler's list " and survived. Sadly, Moshe Taube's mother and young sister were killed in a concentration camp.
