With regard to the matter at hand, I know the following: the events of which I am giving an account took place on 18 March 1942. Early in the morning, the village administrator, Jan Wawrzan, arrived at my place and told me to take an ax, a spade and a pickax. I was ordered to go with him to a place indicated by the German Gestapo.
When we arrived on the spot, we were ordered to dig a pit. In the course of digging the hole, we were kicked and beaten. The Germans didn’t allow us to look around. Once the hollow had been dug, Gestapo men accompanied by German colonists from Karolin led the prisoners, whom they had tied together in fives, to the pit and killed them all, every single group. This was followed by the execution of several more people whom the Germans brought from other places. We were then ordered to level the top of the pile of bodies and fill up the grave. The soil with which the pit was filled immediately became soaked with blood, quivering for some time with the death throes of those who hadn’t succumbed immediately after being shot.
When the massacre was over, the Germans gave us a speech. They threatened to put the whole village to the sword if any of us were proved to be active in the underground movement or if we failed to report the appearance of any partisans in our area. Then they ordered us to run away home. The killing was carried out by the Gestapo and German colonists led by Hejniak and Józef Gramm. The men who were executed were accused of being part of some clandestine organization. Their relatives are still alive, working on their farms in Karolin and all the other villages that suffered the disaster. I know for certain that during their interrogation, which was conducted at the school in Karolin, the convicts were severely beaten. Soaked in blood, unconscious, they were beyond recognition.
I wish to note that some people were murdered in front of their houses, right after the Germans led them outside. This is how, for example, Józef Gładysz and Stanisław Sałek were killed. The residents of Karolin were then ordered to take their bodies to the grave.
At this the report was concluded, read out and signed.
