Because executions by gunfire were inefficient, expensive, and potentially identifiable, intoxication by poison gas--a method used by the Germans to kill over 50,000 mental patients since 1939--was agreed on as the method of choice. Zyclon was originally brought to Auschwitz as a disinfectant and vermin killer. On September 3, 1941, Fritzsch experimented with Zyclon B. on 600 Russian prisoners of war and 250 tubercular patients. He was amazed at the number of people who could be killed at once. On October 15, 1941, a plan for the future camp of Birkenau, designed by one of the prisoners, was approved.

Every morning these prisoners had to endure roll call whereby they would stand for hours at attention outdoors in the cold, wind, and rain or snow. Anyone who fell was gassed.
