In this letter, Paul Rassinier disputes claims made in a book review about his works on concentration camps and the Holocaust. He argues that there is no evidence Hitler or other top Nazis ordered the extermination of Jews. While deaths occurred, he believes the number is around 1 million rather than 6 million. He also argues there is no evidence gas chambers existed in most camps, including Dachau and those in Germany. The question of gas chambers at Auschwitz remains unclear.
