On March 4, at 4 AM, the Latvian, Lithuanian, and Belorussian auxiliaries, commanded by SiPo officers, began to carry out a selection among the Jews: The holders of workers' certificates went to the eastern half of the ghetto, while the “non-workers” – mostly elderly and sick people, and women with children – went to its western half. The Belarusian police searched the ghetto for those who were hiding; they attempted to involve the Jewish ghetto police in this search, but the latter refused. Members of the German military police and the civil administration also took part in the operation. According to many survivors’ accounts, before the roundup the Germans demanded that Izykson provide them with a list of the elderly and the infirm, but the chairman refused, saying: “I am not God; I will not decide who lives and who dies” (several survivors give different versions of Izykson’s last words). On that day, Ovsey Izykson and his secretary were killed along with the other victims.
At 8 AM, trucks drove up to the ghetto gates and began to transport the doomed Jews to the murder site, where pits had been dug in advance. The Baranowicze SD had a quota of 3,000 Jews to exterminate. Being eager to fill this quota, they took many holders of “life certificates” from the eastern section of the ghetto to the pits.
Some eyewitnesses maintain that the trucks arriving at the ghetto gate on that day, or at least some of them, had been gas vans; thus, they transported the already dead bodies to the pits, which had been dug near the so-called Zielony Most (Green Bridge) on the northern outskirts of the town, near the northern railway depot. The victims of the massacre included Izykson and his secretary Henia Mann, as well as the entire Jewish police force, along with their commander, Chaim Weltman.
Nowadays, the killing site is known as Minskii Pereezd (the Minsk Crossing).
