Near Babiy Yar the fascists built a concentration camp that was called Sirez. It was the place where the Nazi kept their captives and forced them to work before murder. Those who managed to survive after the Sirez recall that they had to live in inhuman conditions. Every evening all the concentration camp prisoners had to align on the square, and each fifth or each tenth was shot. If someone managed to escape from the camp, each third captive was murdered. The hospital of the camp was full of ill, weak, bleeding and exhausted people. When it became too crowded, the Nazi removed the patients from the hospital and shot. Every day the Sirez was filled up with new victims. Some of them after a few weeks or months of living in the concentration camp were taken to Babiy Yar, where they were shot or just covered with earth. Small groups of people were put to the basket of the car that functioned so that the gas evaporations penetrated into the basket and people died of asphyxiation. Later the captives were forced to disinter the corpses, which were then burnt in the ovens made of old Jewish tombstones. The ash of burnt people was used as a fertilizer for German fields. The camp prisoners were suffering malicious insults; they lived and dyed in horrible conditions.
