During the Warsaw Uprising, I lived at Dobosza Street 5 in Warsaw. The “Ukrainians” came to our street on 5 August 1944, throwing out the residents from particular houses on Dobosza Street and its vicinity. Around 5.00 p.m., they stormed into the house where I lived. There was an order for all present to go outside.
Taking my child, I went into the yard, and then with the rest of the residents, numbering around 20, onto the street. We were led along Szczęśliwicka Street to Piotrkowska Street. On the corner of Piotrkowska Street and Opaczewska Street, one of the “Ukrainians” stopped me and ordered me to give our child to my wife. Next, after knocking my work certificate from my hand, he shot me with a handgun in the back of the head. The bullet went near my right ear and stopped on a tooth, having come through the hinge of my jaw. I fell and lost consciousness. When I regained consciousness, I felt that the “Ukrainian” was inspecting me, taking money from my pocket. When he left, I managed to crawl into some potatoes by the road. I got through to Szczęśliwice at night. Dr Jasiałkowski and Bober from Okęcie gave me medical help. I had an X-ray done in the City Hospital in Pruszków.
Currently, as a result of the shot, I cannot move the lid of my right eye, the eye often weeps.
(The witness is showing a scar behind his right ear, which looks like a gunshot scar).
The group from which I was taken was led to Zieleniak. I know from the reports of my wife that apart from me, Janiszewski, a resident of the house at Piotrkowska Street 7, was also killed on the way. A “Ukrainian” shot him.
At this the report was concluded and read out.
