For this engineer Becker invented "gazenvagen" - "gas chamber." Test "successfully" passed in Taganrog - under different engine operating modes, different load body, different weather, to people of different ages. The results are reported directly to the Reichsfuhrer. But "gazenvagen" did not meet the low "bandwidth", destroyed at 15-25 people per flight, a problem arose and unloading corpses. Another matter - the gas chambers. In order to assess their effectiveness Himmler in early 1943, he visited the concentration camp Sobibor. Already knowing the tastes superior, especially for his arrival had been brought here from other places of detention 300 girls who have not had time to become emaciated. Try to bring them into "marketable" good food, washed. And during the visit were herded into the gas chambers. Himmler watched through the peephole of agony, and this time did not fall into a swoon, was pleased, even awarded the Commandant Wagner medal. And it was followed by an order to kill women reyskhfyurera continue in this way. And if that is not possible, if you have to shoot in the field, to attract for execution Ukrainian, Belarus, the Baltic police forces from the Russian "volunteers".
