Warsaw, 8 January 1970. Assistant public prosecutor Zbigniew Grędziński, delegated to the District Commission for the Investigation of Nazi War Crimes in Warsaw, heard the person named below as a witness without an oath. Having been warned about the criminal liability for giving false testimony, the witness testified as follows:
| Name and surname | Antoni Czesław Ostrowski |
| Parents’ names | Antoni and Bronisława |
| Date and place of birth | 13 January 1902, in Warsaw |
| Place of residence | Warsaw, [...] |
| Occupation | clerical worker |
| Criminal record | none |
| Relation to the parties | none |
During the occupation, I lived all the time in Praga, Warsaw, in the building at Wileńska Street 3, flat 12. On the first day of the Warsaw Uprising, that is, 1 August 1944, in the afternoon, after the outbreak of the Uprising, some German soldiers came into the courtyard of the building where I lived, dressed in green military uniforms, wearing steel helmets.
I don’t know to what division these Germans belonged. They gave instructions that all the men should go out into the courtyard. Therefore, following this command, I also went out. I remember that in addition to me in the yard there were: Piotr Zdzisław Zajączkowski, Antoni Ablewski (currently residing in Warsaw in the area of Hale Mirowskie, probably on Świerczewskiego Street), Henryk Piotrowski, now deceased, Matusiak and Kubikowski (also deceased) and Raczek, who is probably alive, but I don’t know his address.
The Germans took these men to the square in front of the church to bury victims murdered beforehand. However, the Germans ordered me to stay at home, because they had enough people to carry out these tasks. In view of the above, I didn’t see how many people were buried at the church, who the victims of this crime were, nor do I know the names and the division of the criminals who perpetrated this genocide.
In this case, I know nothing more.
I have read this report personally and I hereby sign it as being truthful.
