On the evening of February 1, 1943 Buczacz was surrounded by a commando unit of German security police from Czortków and Ukrainian auxiliary policemen. Some Jews tried to escape, but were killed by the Germans and Ukrainians; others hid in improvised "bunkers." The Germans and their local accomplices rounded up 3,600 Jews of both sexes and all ages. A few hundred Jews were murdered on the spot. On February 2 the rest were led in groups to the pit at Fedor Hill, prepared in advance by members of a Ukrainian construction unit. At the edge of the pit the Jews were ordered to throw their valuables and money into buckets. Then they were shot.
On April 13, 1943, a week before Passover, members of the Czortków security police carried out an additional murder operation in Buczacz, which lasted three days. Between 2,800 and 3,600 Jews, mainly those discovered hiding, were collected and taken to Fedor Hill (some 600 had already been shot in the city). There, according to one survivor, some local Ukrainians tore the gold teeth from the mouths and wedding rings from the fingers of those about to be killed. All these Jews were shot dead by the Germans and their Ukrainian helpers.
