During the Warsaw Uprising, after a few days of hiding in the ruins, on 11 August I was captured by the Germans and put to work mending Schutzpolizei cars at aleja Szucha 14. I worked in the second courtyard. I was employed there until 16 September 1944.
Working in the second courtyard, I didn’t see the mass executions which took place in the ruined building next to the third courtyard. However, during the period from 11 to 22 August, I saw Gestapo men (dressed in yellow shirts) leading groups of Poles (mostly men) through the second courtyard in the direction of the park. I always heard shorts and moans after a group had passed by. That is why I am stating that mass murders in the area of the former Main Inspectorate of the Armed Forces [GISZ] took place until 22 August 1944. Later, individual people or small groups were taken there, after which I heard shots.
I would like to add that after each execution an empty platform would arrive in the backyard and leave soon after, loaded with clothes. The platforms, I noticed, took the clothes to Litewska Street, I don’t remember the house number, but it had formerly held a nursery. I heard that men detained in the labor camp were made to clean up. They were executed around 20 August. I noticed that until 11 August, on average five, six parties were led in to be executed. The parties were led in particularly frequently during the first days I was working there.
