My stepdad, God rest his soul, was a member of the 296th Combat Engineers, and assisted in liberating the Buchenwald camp. His unit compelled the citizens of Bad Berka, Germany, to witness the atrocities at the camp. It was very difficult for him to talk about it.
Many liberators have already passed on, thus it is our job to remind the public of both the victims & their liberators, while countering those which state, 'it never happened'.
