I was arrested on 8 July 1940 and charged with helping Wiejowski from somewhere around Tarnów – the first [Polish] prisoner to escape, as well as with seeking contact with prisoners and wanting to restore the Polish State. For this reason, I was first detained in the bunker for 18 days and interrogated by Grabner during that time. I was given food only once during my 18-day detention in the bunker. I was then sentenced to death, but the verdict was changed to five years of labor in a quarry and 75 lashes. Having received 75 lashes, I was sent to hospital because two of my ribs were broken, my clavicle was fractured and a piece of flesh in my right thigh was actually torn off.
When I recovered, on 18 June 1941 I was sent to Mauthausen, where I stayed until the end. Since I spent almost the entire time of my stay at Auschwitz in the hospital, I cannot provide any important information on [illegible] of the armed crew of the former Auschwitz camp.
