I first noticed that the Germans were executing people in Firlej in the spring of 1940, although I don’t remember the exact date. That day a number of trucks drove up to the sands of Firlej. One of them carried the people who were condemned to die. The victims were taken from the trucks to the sands and shot there. In the meantime, other vehicles loaded with prisoners were waiting their turn. The empty trucks returned in the direction of Radom, while those carrying arrestees drove up to the sands. Some 200 people were executed that day. I went up to the execution site in the evening and saw bone fragments and pools of blood in the sand.
From that time on, the executions became frequent and regular. On average, the shootings were held two or three times a week.
In the autumn of 1943, the local residents were evicted. The Germans screened the area with mats and started burning the bodies. You could see smoke rising above the sands and smell the stench of rot from that direction.
Once they had finished the incinerations, in the spring of 1944, the executions resumed afresh. Once again we heard the sound of shots coming from the direction of the sands.
In the summer of 1944, the Germans forced me to work on the burying of the bodies of the murdered victims. At the time, I saw the corpses of around 40 people, although by the time of my arrival a number of the bodies had already been buried.
These executions lasted until the final days before the entry of the Red Army.
The report was read out.
