On August 10, 1942 the German Security Police from Brześć nad Bugiem, with the assistance of the German regional order police (Gendarmerie) and the Ukrainian auxiliary police, headed by Yakov (Akim) Blyashuk, surrounded the ghetto. The Jews were ordered to gather with their belongings at the main gate of the ghetto on the pretext that the entire area had to be disinfected. According to another testimony, the Jews were told that they would be sent for work. Then they were taken from the ghetto on foot, under the guard of Ukrainian auxiliary police, outside the town to the Jewish cemetery. The old and sick Jews were taken by cart. When they arrived close to the Jewish cemetery, the Jews were taken to a fenced-off area where military barracks, constructed initially for Soviet POWs, were located. Then a selection was conducted by Fritz Michaelis, the Gebiteskommissar of Kamień Koszyrski, assisted by the members of Judenrat, on the basis of permits issued to specialist workers. Several hundred Jews, mainly young specialists, who were given those work permits, were locked in the barracks. The rest, after being forced to strip naked, were taken in groups to pits that had been prepared in advance at the Jewish cemetery, made to lie facedown, and then shot to death in the back of the head with machine-guns by the members of a Security Police unit. Along with the Jews, several dozen or more Roma [Gupdy] people were shot to death at the site at the same time. According to a German report, in mid-August the Security Police reported the "special treatment" of 3,399 Jews in Kamień Koszyrski County; of those at least 1,700 were shot in the town itself. Gebietskommissar Fritz Michaelis personally headed this murder operation. In the course of the following days, some Jews who had hid in the ghetto were dragged out of their shelters and shot to death at the murder site by Ukrainian policemen. On November 2, 1942 the Kamień Koszyrski ghetto was liquidated: its remaining inmates were taken to the site and shot to death by a German unit.
