I was born and currently live in Stoczek Węgrowski (Siedlce voivodeship). Certain periods of my life under occupation I can recall quite well [as they are sealed in] my memory. I remember that in July or June of 1942 three Jews from Warsaw came to my father. I do not remember the names of those Jews, but I know that they arrived at my father’s right after or [just] before the ghetto in Warsaw was liquidated. We did not know them before. There were three of them: two men, about 25 years of age, and a girl, about 20 years old. My father sheltered them in the potato cellar, about 100 meters away from our house. They spent days and nights there. My [father] would not visit them during the day, only in the evenings. During the day us siblings would do the shopping in Stoczek, our mother would cook meals [for the Jews], [but] only in the evenings did my father deliver the food to them. Some evenings they would come by the house, but very rarely. I would speak with them sometimes. My mother would bring them the bread she baked, soup and groceries. My parents ran a farmstead. After about two or three months, when [the Germans] organized a roundup of Jews in Stoczek, three more Jews from Stoczek joined us. I knew one of them, his name was Hajkel and he was a groat maker, about 30 years old. The second man I did not know. He was about, or narrowly over, 30 years old, but I do not know his name or profession. The girl could have been about 30 years old or under, I do not know her profession. My father prepared a second hideout for them at our farmstead, in a close proximity of about 50 meters. These three Jews stayed in this hideout separately and my father also would bring them food which we, that is my mother and our entire family, prepared for them. The evening deliveries of food by my father went on for a year and a half. I remember that when the revolt broke out in Treblinka, several more Jews sheltered in these two hideouts, 17 people altogether. Until September 1943 my father provided them with food in the hideouts. I remember that one day in September 1943 at 6:00 a.m. a man leading a cow to pasture visited us. He told us that the Germans were in the forest near our buildings. I drove the cows to pasture and came back home. As soon as I came back, I saw Germans in the yard and I saw that my brothers Henryk and Wacław were at home together with my mother and father. While my mother stayed inside the house, I was at the well with my brothers. I asked if I should go get the grazing cows which I was in charge of and he [sic!] agreed, ordering me to go get them. I ran towards the forest, moved the cows a bit and ran to the house of my brother Józef, who lived in the township of Stoczek Gajówka Wschodnia. I told him that the Germans were at our place and instead of returning home, I ran to the house of my brother Kazimierz Postek, who lived in Stoczek Wieś Kolonia. I stayed there without saying anything to him at first, only assisting my brother in threshing the grain with flails. Once my brother’s wife arrived, she said that the Germans killed many of the Jews who were staying with us and planned to murder our entire family. That same day, my brother Kazimierz and I ran to his brother- in-law’s house in Lipki, and spent the night there. The following day I went to the house of my first cousins, who lived in Marianów. Kazimierz, my eldest brother, returned home to care for his farm and I stayed in Marianów with my first cousin for a month. Then I returned
