After the partisan attack on German soldiers near Topola on 2 October 1941, general Franz Böhme ordered the shooting of 2,100 hostages, of whom 805 "Jews and Gypsies" should have be taken out of the camp in Sabac. The Jewish community in Sabac at the time had only a few dozen members, but there were about 1,200 Jewish refugees from Austria, Poland, Czechoslovakia and other countries in the city from before the invasion of Yugoslavia. It was the so-called "Kladovo Transport" group, which had previously been stopped in 1940 in Kladovo, a town on the Danube, on the border with Romania, and returned to Sabac, where they were caught in the Nazi occupation.
All men over 16 were separated from the group and shot on 12 and 13 October in Zasavica with Jews and Roma men from Sabac.
After the war, the National Commission of Serbia for the Investigation of the Crimes of Occupiers and their Accomplices set up a special committee with the task of carrying out exhumations in in Zasavica. Stevan Jovicic, an official from Sabac, who took part in this work, testified that, during the exhumations the Commission had found the bodies of 868 killed, around seventy of whom were Roma from Sabac. Their nationality was established using personal documents found on them, while others were recognized by their families.
The execution site is not marked and is used in farming. In its vicinity there is a small monument in memory of those shot.
