Surviving the holocaust 'Freddie' on bbci player now is another fascinating story.
Very powerful stuff, I agree it's hard to really feel the horror until you see it, story's don't carry the same message as the pictures, the army was right to video it to as they they say it is not forgotten in history, or denied in future, as terrible and difficult as it is to watch.
People returning were changed people, we all change with experiences and age and these experiences were as life changing as anything we are likely to experience, sometime telling the story's were a form of therapy, maybe they felt the need to tell someone so they could tell the tale in future years, torn between the pain and the need to inform, trauma that must have been difficult on a daily basis. Many never spoke of the war, easier to box it away in your mind.
