Until approximately 30 August 1944, I was in the Śródmieście [City Center] district, at Hoża and Krucza streets. Next, at the beginning of September, I found myself in Tamka Street. Until Sunday in the first days of September, I do not now remember the date, I remained at Tamka Street 4. On that day the house was bombed. Nearly all of the residents left the building; some went to Śródmieście, while I moved to Tamka Street 33. The house was bombed on Wednesday, I do not remember the date either, early in the morning, and therefore I moved to the garden of the Sisters of St. Casimir, which was adjacent to house no. 33.
Around noon that day the Germans commenced an attack and quickly occupied the area of the nunnery. Speaking through an interpreter, they informed those gathered there that if anyone used a weapon, everyone would be shot. Next, they ordered all the people to vacate the premises of the nunnery, leaving only some of the sisters and wounded in the hospital that had been set up there during the Uprising.
The rest of the populace – the number of whom increased steadily while walking along the streets, since the Germans were throwing people out of all the houses – was led along Topiel and Browarna streets to Bednarska Street, and from there along Krakowskie Przedmieście Street, Ossolińskich Street, through Teatralny Square, and then along Senatorska Street and Chłodna Street to the church in the Wola district.
Here the women were separated from the men, and then – on the same day – everyone was transported from the Western Railway Station to the transit camp in Pruszków.
At this point the report was brought to a close and read out.
