I witnessed two executions carried out by the Germans in 1944 in the market square in Zwoleń. The first took place on Good Friday 1944, before noon I think. I observed it from a window. I saw the victims being led towards the wall, and then I heard shots. I didn’t see the bodies. I heard that more than 20 people were killed. In the evening of 19 June [19]44, the Germans (gendarmes and Gestapo men) brought two truckloads of Poles to the marketplace. The Germans stumbled upon me while I was returning from the cemetery, and turned me back to the market square. Many other people were also forced to assemble there and watch the killing. A few men, nearly all of them handcuffed, would be taken from the trucks, arranged in a row and ordered to kneel by the wall. Revolvers were then aimed, point blank, at the backs of their heads, and the triggers pressed.
I saw that a larger group of Germans was standing some distance away. The kneeling men were dispatched by no more than two men at a time; they wore Gestapo uniforms, for I distinctly remember that they had death’s heads on their helmets and caps. I recognized the following residents of Zwoleń, friends of mine, amongst the victims: Nowakowski, Kordziński and Koseł. All the victims passed by me on the way to their deaths, however they said nothing, and indeed emitted no sound. The dead were placed on horse-drawn carts and buried near the cemetery in Zwoleń on the same day. I know that before this act of murder was committed, German aircraft dropped leaflets informing of a planned execution of citizens of Zwoleń, which would be held if two officials of the Radom District – previously kidnapped by partisans – failed to turn up.
