Sometime towards the end of 1941 a story spread across the camp that a new SS-Sturmbahnführer had come to the camp from Berlin and he was later revealed to be Franz Krause. With his arrival, a change for the better was expected. Sadly, the direct observations of my fellow prisoners and myself did not bear out these hopes.
I saw for myself when during an evening roll call, when prisoners were usually whipped at the box, Krause, the same person whom I recognize in the photograph presented to me, came up to the prisoner being whipped by SS men and kicked him a few times.
Later, in the course of processing food transports on the camp ramp, where prisoners’ transports also arrived and where Krause used to be present for selections of the newcomers, I saw him personally strangle elderly Jews, grabbing them by their throats, and kick people in the stomach so that they would fall to the ground, and I had no opportunity to see if they ever got up. Krause proved his utter vileness not only to the prisoners but also to the SS guards, from among whom those of better moral qualities and those who could be trusted warned me and my comrades against Krause. A Slovak from the guard company told me that Krause had come to his watchtower and carried out a surprise inspection. Then, having found some cigarettes, he had placed him under arrest for two weeks. It appears that Krause had been sent specifically to tighten up discipline and see to it that the camp crew would treat prisoners with greater ruthlessness.
Some time after that, Krause was transferred to the Birkenau camp, from where word spread that he had been transferred. It was as if they had opened a stage for him to harass women imprisoned at that camp.
In January 1945 the camp was evacuated. I was looking for any hideout so I would not have to leave together with the prisoners being evacuated. I had just seen that Krause, flanked by a couple of SS men, was heading toward the kitchen where I worked. He held a revolver in each hand and the SS men had guns ready to fire. This was how Krause was searching for prisoners hiding in the blocks, i.e. prisoners who did not want to leave the camp under German escort and go West. When I saw Krause, I ran with a few comrades of mine to the camp hospital, where those suffering from typhus lay in the barrack, and I hid in the attic. In the meantime, Krause with his SS team had been prowling around the blocks for some ninety minutes, shooting at prisoners he came across. When he left and I could come out of hiding, I saw a very talented young Belgian doctor shot dead at the desk in the office, and another man, a medical student, I think, also a Belgian, who was severely wounded. A prisoner from the kitchen, a Reichsdeutscher who was an acquaintance of mine, told me that Krause had executed these people personally. Apart from these two, I saw two bodies in the kitchen, next to the caldrons, and these people had also been shot by Krause. In that way, Krause, through terror, collected some two hundred people from among those who had been hiding and rushed them west, despite the fact that this group included people who could not walk because they had not completed their treatment at the hospital.
