In August 1944, my son Kazimierz Chojnacki (residing in Warsaw at Muranowska Street 14) took part in the Warsaw Uprising. My brother, Stanisław Wiesław Olszewski, then residing at Górnośląska Street 12 in Warsaw, saw my son fighting at the barricades in the Old Town. My son was accompanied by my son-in-law, Telesfor Hedrysiak (residing in Warsaw at Muranowska Street 14). He was wounded during fighting on 20 August 1944 and since that time I haven’t heard from my son. He has disappeared without a trace.
