I saw that everyone had gone behind the barn. There we saw a sight beyond words. It was Monday, July 12, 1943. Polish farms in the colony named Zapust are burning. It was one and a half kilometers from our Wólka. There was a small village of Krzemieniec between Zapust and our village – there were The Ukrainians – there was silence. At first we thought that the fire was carried by the wind, but after a while we saw that the buildings were lit up against the wind and we could hear people screaming, cattle roaring and terrible barking of dogs, plus single shots. Dad and uncle said at the same time: „They are murdering Poles, what to do, in a few minutes they will be murdering us. Let's go to Mr. Kowalczuk – we will learn something” there. Izydor Kowalczuk was a Ukrainian, but he was a very smart, educated, rich man, he stayed with Poles more. He had no company with the Ukrainians. Before the war of 1939, he was the head of the commune of Chorów. When he saw his father and uncle in his backyard, he said with horror: „Gentlemen, run away, load the most necessary things on the carts and run away. A band of Banderites murders everyone without exception. I am also leaving”. He lived in a Ukrainian village, but the first buildings from our village were separated only by a road, it was easy to get to. When Father and Uncle were coming back, they told all the neighbors that we were leaving. We started loading on carts. We had two carts, three horses and two 6–month–old foals, three cows and a one‑year‑old heifer, pigs, sheep, chickens, dogs. All of this was left unattended. Grain supply – close to a hundred quintals, all agricultural tools: reapers, threshers, grain cleaners, sash bags, furniture, utensils – all this was taken by the Ukrainians  […] The whole village, all the carts were on the road ready to depart. The sentries saw someone running from the side of the fire. They thought they were bandits. After a few minutes, they realized that someone was escaping. Indeed, it was a young boy, 18, Tadeusz Kicki. The bandits murdered his parents and sister. He hid in the crop, dislocated his leg while running to our village, and somehow he reached us on a stick. My mother entered the apartment again, took the Cross off the wall, went out onto the road, crossed the entire transport with her Cross, sat on the cart and we set off.

All Poles escaped from Zapust, except Marian and Stefania Kuźmiński, who had six children, the oldest of whom was 13 years old. During the night, the children were taken to the Ukrainians they knew, and they slept in the corn. When they went to fetch the children in the morning, they did not find anyone in the house, neither them nor the children. Most likely, someone reported that the Ukrainians were hiding Polish children and were murdered with them. Most likely, they were taken to the church in Kisielin and murdered there. It was a very common practice then used by UPA thugs, who probably could not stand that they did not manage to murder all Poles in the Kisielińska temple, and some of them defended themselves in the presbytery. When the Kuźmiński family did not find their children, they came to Zaturzec. He's tearing his hair out.
