as the death camp was liberated by british and canadian troops in 1945 , it was torched , and at least part of that suffering was destroyed forever as the buildings , along with the reichskriegs flag and hitler portrait which adorned them , were consumed by flames .
these never-before-seen images were captured by reverend charles martin king parsons , who said he is proud that his great-grandfather was brave enough to take the pictures , so future generations do not forget what happened .
