The Prebilovci massacre was a mass murder that occurred in the Independent State of Croatia during the second world war ,committed by the croatian ustaše. On the 6th of August 1941 the ustaše killed 600 women and children by throwing them, still alive, into the Golubinka pit.
The massacre began in the village of Prebilovci itself, with the ustaše targeting young children, holding infants by the feet and dashing their heads against the walls of the school to kill them. They then drove the women and children prisoners they had captured to the local cave formations. Golubinka was one of these caves, and the ustaše took small groups of prisoners to this cave, pushing them down into the depths - with an initial vertical drop of 27m, followed by a steep slope that measure 100m in height. 300 children and infants were thought to have been killed that day alone, having been tossed into the air before falling into the pit.
In 1990 the Golubinka pit was opened for serbian priests to hold a memorial service over the remains of the victims. In total 1550 remnants were removed from the pit and, combined with the remains found in other local caves, 4000 bodies were recovered.
