"The war with the Soviet Union began in June 1941, I think. And I believe it was two months later, or maybe three, that Heydrich sent for me. I reported. He said to me: "The Führer has ordered physical extermination." These were his words. And as though wanting to test their effect on me, he made a long pause, which was not at all his way. I can still remember that. In the first moment, I didn't grasp the implications, because he chose his words so carefully. But then I understood. I didn't say anything, what could I say? Because I'd never thought of a … of such a thing, of that sort of violent solution. … Anyway, Heydrich said: "Go and see Globocnik, the Führer has already given him instructions. Take a look and see how he's getting on with his program. I believe he's using Russian anti-tank trenches for exterminating the Jews." As ordered, I went to Lublin, located the headquarters of SS and Police Commander Globocnik, and reported to the Gruppenführer. I told him Heydrich had sent me, because the Führer had ordered the physical extermination of the Jews. … Globocnik sent for a certain Sturmbannführer Höfle, who must have been a member of his staff. We went from Lublin to, I don't remember what the place was called, I get them mixed up, I couldn't say if it was Treblinka or some other place. There were patches of woods, sort of, and the road passed through — a Polish highway. On the right side of the road there was an ordinary house, that's where the men who worked there lived. A captain of the Ordnungspolizei welcomed us. A few workmen were still there. The captain, which surprised me, had taken off his jacket and rolled up his sleeves, somehow he seemed to have joined in the work. They were building little wooden shacks, two, maybe three of them; they looked like two- or three-room cottages. Höfle told the police captain to explain the installation to me. And then he started in. He had a, well, let's say, a vulgar, uncultivated voice. Maybe he drank. He spoke some dialect from the southwestern corner of Germany, and he told me how he had made everything airtight. It seems they were going to hook up a Russian submarine engine and pipe the exhaust into the houses and the Jews inside would be poisoned. I was horrified. My nerves aren't strong enough … I can't listen to such things... such things, without their affecting me. Even today, if I see someone with a deep cut, I have to look away. I could never have been a doctor. I still remember how I visualized the scene and began to tremble, as if I'd been through something, some terrible experience. The kind of thing that happens sometimes and afterwards you start to shake. Then I went to Berlin and reported to the head of the Security Police."
