In the early hours of September 1, 1942, the Ukrainian police surrounded the ghetto. At 6 a.m. the German Gendarmerie (rural order police) and Ukrainian police searched the ghetto for unskilled workers, i.e. "the dead ghetto." The Jews were forced out of their houses, collected at one of the gates of the ghetto (or, according to another testimony, near the Judenrat building), loaded onto trucks, and driven to Piatydni. The forced laborers in the ghetto for skilled workers were not allowed out to work. As the day wore on, trucks full of clothing began to return to Włodzimierz Wołyński. That afternoon, at 12:30, the Germans and Ukrainian police entered the ghetto for skilled workers ("the living ghetto") as well, and took many of its inmates to Piatydni. Upon arriving at the murder site, the Jews were forced to strip naked and to enter the pit in groups. Then, while lying facedown, they were shot to death in the back of the head with machine-guns by an SD unit (and some Gendarmerie men). Then another group had to lie down on top of the dead bodies and, in turn, was shot to death. The trucks with new victims shuttled back and forth during the next days. The members of the German administration set up a table at the killing site so that the killers could not only register their victims, but also eat and drink during the shooting. This murder operation ended on September 15, 1942.
On November 13, 1942, Ukrainian police and Gendarmerie surrounded the ghetto for unskilled workers. The latter were loaded onto trucks and taken to Piatydni, where all of them were shot to death in pits.
The Gebietskommissar of Włodzimierz Wołyński, Wilhelm Westerheide, was personally in charge of these two murder operations.
