Anywhere from 100k to 400k Jews died in concentration camps. The total numbers of deaths is still unknown due to the massive disinformation campaign. Most Jews who died, did so from lack of nutrition and illness with lack of medical supplies the last 3 years of the war in Europe.

How do I know this? The website bestgore had a holohoax section with several concentration camp survivors interviewed . One of them was a surviving woman who at the time of the events was 12 years old. She said she was allowed to organize plays for the camp and was often moving around different sites because the guards trusted her and she saw many different sites organizing plays for their entertainment. She says most of the death at the camps came in the form of mall nutrition and illness due to lack of supplies. She says no one died in showers with toxic chemicals, only those who tried to escape would be shot at.
