Extract from the trial of Anton Kaindl, former commandant of Sachsenhausen Death Camp

On Jewishgen.org you can read an extract from the trial of Anton Kaindl, former commandant of Sachsenhausen Death Camp:

Kaindl: In march 1943, I introduced gas chambers for the mass exterminations.
Public Prosecutor: Was it your own decision?
Kaindl: Partially yes. Because the existing installations were too small and not sufficient for the exterminations, I decided to have a meeting with some SS officers, including the SS Chief Doctor Baumkotter. During this meeting, he told me that poisoning of prisoners by prussic acid in special chambers would cause an immediate death. After this meeting, I decided to install gas chambers in the camp for mass extermination because it was a more efficient and more humane way to exterminate prisoners. [...]
Public Prosecutor: Accused Kaindl, did you receive the order to destroy any evidence of the murders committed in the camp?
Kaindl: Yes. On February 1st, 1945, I had a conversation with the chief of the Gestapo, Muller. He ordered me to destroy the camp with artillery bombing, aerial bombing or by spraying gas. But due to technical problems, this order coming directly from Himmler was impossible to fulfill.
