Warsaw, 30 March 1945. The testimony of citizen Stanisław Kleniewski, born on 20 November 1901, residing in Warsaw at Koleńska [Kobielska?] Street 10/7.
Concerning: the mass execution carried out on 12 November 1943 at 11.00 at Kępna Street, corner of Jagiellońska Street.
On 12 November 1943 at 11.00, I observed the following through the front window of house no. 14 on Kępna Street: Two Black Marias, one open police vehicle and four motorcycles with armed Gestapo officers drove up from Zygmuntowska Street. The first Black Maria was filled with prisoners, while the second carried the SS men who would carry out the execution. The rest were escorts.
While the vehicles were driving up, opposite the house at Jagiellońska Street 16, one of the prisoners jumped off. He was about 22 years old. He was dressed in a light steel-grey suit. Having jumped, he started running in the direction of Brukowa Street. After covering a few metres, he was shot down by the escorting gendarmes and finished off with a Luger by one of the Gestapo officers.
Following this incident the vehicles stopped at Kępna Street (the area had been previously surrounded) and all of the prisoners – 24 in total – were led out of the first Black Maria. All wore light steel-grey suits (regulation clothing, in all probability) and had their eyes covered with black blindfolds. They were placed along the wall of the grain warehouses of the municipal slaughterhouse at Kępna Street. They were executed in two groups (I couldn’t determine the number). The condemned persons stood facing the wall, with their backs to their murderers and their hands stretched backwards. The SS execution squad was gathered in the street (some kneeling, six standing with their rifles), and they fired when their officer commanded. Single salvoes. After each salvo other murderers would approach and finish off the wounded with their revolvers. The next group of condemned persons would be brought up to the same spot immediately after the preceding execution, and be dispatched in the same manner.
I would like to add that if any of the prisoners who were brought out of the Black Maria struggled and refused to go forward, they would be hit with rifle butts.
After the execution was over, an open truck with eight workers arrived on the scene. These people loaded the bodies and drove off in the direction of Zygmuntowska Street. Next, a truck from the Municipal Department of Sanitation drove up and used motor pumps to wash the blood off of the street. Some 40 minutes after the execution, a priest in a surplice walked up to the spot and blessed it.
I have testified truthfully. I have read the report before signing it.
