From 17 January 1943 to 22 July 1944 I was incarcerated in the concentration camp in Majdanek. At the time of my arrival at the camp, Muhsfeldt served as the heard of the Krematorium kommando and Waldkommando (a group of laborer-prisoners who opened mass graves and burned bodies in the vicinity); I recognize him in the photograph presented to me (the witness was presented with a photograph with the following inscription: Erich Muhsfeldt, appended to a letter from the Kraków District Commission for the Investigation of German Crimes, dated 7 August 1947, no. 779/47). At first, I didn’t come across Muhsfeldt at all; I only heard that he was a cruel man, but I am unable to provide more details. After a partial evacuation of Majdanek in the spring of 1944, Muhsfeldt was appointed a commandant of the camp field, and at that time I met him almost every day. I don’t know who ran the crematorium at the time. As a commandant of the field, Muhsfeldt was very cruel and took every opportunity to beat the prisoners. On several occasions I found myself in a group of prisoners selected by Muhsfeldt for punitive exercises. They were organized because the food that had been brought in by two prisoners was intercepted.
At this time Muhsfeldt severely beat Władysław Krupski, currently residing in Poznań and employed in a branch office of the General Board of the Cooperative Publishing House “Czytelnik” (“Głos Wielkopolski”).
The function of Schreiber [camp registrar] in Majdanek was performed by Olszański, currently employed in the state-owned Tractors [and Agricultural Equipment] Manufacturing Company with its main seat in Łódź. Olszański can provide a lot of information about Muhsfeldt.
At this point the report was brought to a close and read out.
