When the Warsaw Uprising broke out, I was at Bieniewicka Street 34. Until 14 September 1944, our area, controlled by the insurgents, was relatively peaceful. It was under fire from the Germans at the barracks in the Gas School at Gdańska Street 6, so we couldn’t move around freely. At theend of August or at the beginning of September, I don’t remember the date, some inhabitants of Marymont, on German orders, left, heading in the direction of Żoliborz. However, although the Germans were supposed to execute those who had stayed behind, many people didn’t obey the order. Around 10 September, the Germans from the barracks ordered us to move from our area to the house at Gdańska Street 4. The inhabitants from all the neighboring streets had been gathered in the shelter of that house.
On 14 September, at about 10.00 a.m., the house at Gdańska Street 4 was surrounded by German troops and Vlasovtsy. The insurgents had already managed to retreat from the house to Żoliborz. The Germans threw a grenade into our basement, as a result of which three people were killed, including Zofia Gandys and Jan Kowalski. The others left the basement on German orders. We were led down Gdańska Street to the corner of Kaskadowa Street. There, the Germans segregated us. Women with children remained on the corner of Kaskadowa and Gdańska streets, and the men were taken back to house no. 21, which the Germans had already burnt down. The corpses of six executed people were lying on the pavement near the debris of the house. It looked as if they had been trying to escape and had been killed on the run. Since there were no inhabitants on Gdańska Street, as all had left on German orders, we couldn’t find out who these people were and how they had been killed. I recognized the body of the owner of the house no. 15 on Gdańska Street, Janina Józińska née Kwiecińska. The others – a man, a boy and a number of women – were allegedly her relatives. The Germans told us to dig a grave by the paling of the garden of property no. 23 and bury the corpses there. We found a few more corpses in the garden. In total, we buried some ten people in that grave.
Next, the Germans told us to go all together, along with the women, to the Central Institute of Physical Education. From there, the Germans led all the civilians gathered at the institute through the Bielany fields to the Kościuszko camp in Powązki, and on the following day to St. Adalbert’s Church in Wola. The Germans took young men from the church.
I don’t know what happened to them.
The others were transported from the Western Railway Station to the Pruszków transit camp.
As for other crimes committed in our area during the Uprising, I heard that on Gdańska Street vis à vis Kaskadowa Street the Germans executed the family of the owner of house no. 25 on Gdańska Street, Filipkowski, currently living somewhere in the West. I don’t know who could provide more details about this crime.
At that the report was concluded and read out.
