They couldn't even agree about where they were supposed to have been located. This is also true of the so-called scholarly literature, which is full of contradictions. But they know more about that than I do. I want to try to explain how such stories get started. When I tell fairy tales to my grandchildren, I often speak as if I am there in the story myself, so that the children will believe them.
Many people also have a tendency to embellish what they say.
Some enjoy getting others to believe their false tales. Every veteran knows about these. Those interned in prison camps particularly like to invent and spread such stories. So I have an explanation for how the story got started that corpses were burned in open fires at Auschwitz. My maid, Olga, once told my mother, who was visiting me at Auschwitz, about a fire in which people were being burned.
