Having been familiarized with the wording of Article 165 of the Code of Criminal Procedure, the witness testified as follows. After I married Henryk Sieradz I moved to the township of Zambrzyniec, about five kilometers away from the township of Stoczek Węgrowski. My paternal uncle Stanisław Postek with his wife Julianna and their children, that is seven boys and three girls, lived in Stoczek and ran a farm. I don’t recall the exact date, but it was in 1941. I know that Stanisław Postek sheltered Jews [who] lived in a hoophouse near the forest. This family was persecuted by the Germans for sheltering Jews. When [they] learned – actually, were tipped off – that there were Jews at my uncle’s, they came over and immediately shot all the Jews, my uncle and aunt. I should just clarify [this part of the testimony]: my aunt Julianna Postek was murdered on the spot; she was bludgeoned. Next [the Germans] set the living quarters and farm buildings on fire and took my uncle Stanisław Postek and his sons Henryk and Wacław to Treblinka or Auschwitz. The rest of the children were not home, so they were hidden by neighbors – I was among them, sheltering the Postek children Celina Postek, Zofia Postek and Jerzy Postek in my house in Zambrzyniec. [During the action] those children were at school. They were told what happened to their parents, so they ran from the school in Stoczek to my house; otherwise, they would’ve been murdered by the Germans. I do not know what military unit those Germans were from. I believe it was the Gestapo. The Postek children spent about a month with us and later their eldest sister picked them up and took them to Stoczek. Had those children been at home, they certainly would have been murdered.
That is the end of my testimony in this case.
At this the report was concluded and read out on 7 April 1991 at 12:30 p.m. I have signed the report after having confirmed it is consistent with my testimony.
