Victims were not all Italians because many killed citizen were anticommunist Croats and Slovens: many women were raped before killing. Historians like Raoul Pupo or Roberto Spazzali estimated the total number of victims at about 5,000; Guido Rumici calculates from 11,000 upwards including all people died in concentration camps; Giampaolo Pansa calculates around 15,000 always including all people died in concentration camps; fascist politician and historian Giorgio Pisanò calculated total from 10,000 upwards. It was never possible to extract all the thousands of corpses from foibes because some of them are deeper than several hundreds meters. Until few years ago it had been able to extract from the pits just a small number of bodies, less than six hundred while other sources are attempting to compile lists of locations and possible victim numbers. Almost all historians calculate hundreds of victims real assassinated by hard pushes to foibe while the estimated number of total people killed in concentration camps is disputed and varies in thousands; probably only a part of total cadavers was hided in foibe but a lot of bodies were accumulated in mass graves. Main concentration camps were in: Borovnica, Skofja Loka, Osijek, Stara Gradiska, Sisak, Zemun, Vrsac, Osseh, Aidussina, Maribor.
