"On this day in 1944, a German-born Jewish girl and her family, who had been hiding in German-occupied Holland, are found by the Gestapo and transported to various concentration camps. The young girl's diary of her time in hiding was found after her death and published. The Diary of Anne Frank remains one of the most moving testimonies to the invincibility of the human spirit in the face of inhuman cruelty."

But I expect you are right= Anne Frank was not murdered at Bergen-Belsen- had she avoided becoming ill, she would have been just fine. We should just lighten up.
