On 16 May 1940, I was transported to the concentration camp in Ravensbrück, where I stayed until May 1944. I was then transported from Ravensbrück to Hanover, where I stayed in an ammunition factory until March 1945. I was transported back to Ravensbrück, where I was liberated by the Swedish Red Cross.
During my first detention in Ravensbrück, Maria Mandl was an ordinary overseer. During my second detention in Ravensbrück, she held the positions of senior overseer, camp commandant, and overseer of the punishment cell.
I would characterize Maria Mandl as a sadist, a woman profoundly hostile and abusive towards Polish women. Mandl tormented prisoners, tortured and beat them senseless. In the winter she ordered prisoners to stand outside in the cold with no stockings or shoes, until [some of them] died.
A fellow prisoner who could provide information about Maria Mandl’s conduct is Kazimiera Chytra [Hytra], residing in Szamotuły, Świerczewskiego Street 10.
The report was read out before signing and concluded.
