The death certificates recorded in the death books tell us. They show that only 2060 of the 68,864 deaths were from typhus. Butz and Mattogno place the cremation capacity of Auschwitz at about 1000 per day, or 30,000 per month after the new ovens were built. In August 42 during the worst period of the typhus epidemic, the Auschwitz-Birkenau camp had 21,451 male prisoners. The information on the female population is missing. However, it is known that the female population was about 8200 in December 1942. This means that the camp authorities were building enough crematorium capacity in the summer of 1942 to incinerate the entire population of the camp in a month.
