 Contemporary figures are much higher.According to research conducted by Polish historians on the data released by the prison services in 1993, the list of prisoners who died at COP Jaworzno and its filias between 1945 and 1956 consists of 6,987 names, which was a figure much greater than in any other Polish detention center (for a comparison, approximately 2,915 prisoners died at the second most-lethal work camp in the Stalinist Poland, the Central Labour Camp in Potulice, mainly from typhus and dysentery).The victims were mostly the German "Volksdeutsche".
