Czewel Forest
According to one testimony, on August 22, on the eve of the liquidation of the ghetto, its inmates set many buildings on fire to distract the Ukrainian auxiliary policemen who were guarding the ghetto and to run away. Several dozen succeeded in escaping, but they were later caught by Ukrainian auxiliary policemen and shot to death. The next day the remaining Jews of the town were shot to death in the forest near Czewel village, apparently by a German unit.

Somow Lake
According to one testimony, on August 5, 1941 early in the morning, a truck with several Gendarmerie (German rural order police) men and Ukrainian auxiliary policemen arrived in the town. They drove the Jews out of their houses or caught them on the streets and collected them in the town's synagogue. After a selection was carried out, during which skilled artisans and women with little children were separated from the others, a group consisting of the remaining 260 Jewish residents (men, women, teenagers, and old people) was taken on foot to the town of Maciejów. They were told that they were going to work. According to the same testimony, upon arriving in the vicinity of Somow Lake [Somne Lake] they were all shot to death, apparently by the Gendarmerie men.
