Growing his grandfather's „Białka”, Mr. Julian (Julian Jamróz – comment by: Stanislaus Żurek) witnessed the preparations for the murder of a group of prisoners, among whom at least one hundred belonged to the Polish underground. The murder took place in the suburbs of Rivne – in the so–called Brickyard. Its author was the Gestapo and the Ukrainian police. – This brickyard was the so–called clay pits, i.e. pits from which clay was selected for bricks to build Rivne, he says. – They were surrounded by meadows, which local residents did not advise to enter when the flowers are in bloom. They gave off such an intense odor that it made you feel dizzy and even unconscious. In one of the pits from which the clay was selected, the Germans organized the „killing room”. Me and a group of boys who often accompany me to shepherd the cows became interested in why the Germans go to this clay pit. It wasn't easy to sneak up on her. There was a watch at the clay pit. We somehow managed. With my own eyes I saw some beams, boards, a pile of ropes, a lot of cut Christmas trees, axes and some barrels with black goo. A few days later, black smoke began to spread over Rivne from the clay pits. It turned out that the Germans built gallows in the clay pit and hanged some of the prisoners. Others were shot. The bodies of the murdered were arranged in piles, covered with Christmas trees, poured with slime from barrels and set on fire.
People knew what was happening. They walked around depressed, prayed, etc. Today I remember that although historians write about only one murder, there were probably more in these clay pits. One of them took place at the turn of July and August. Some of the cereals were still in the fields.
