The Ustaše themselves claimed that they had killed many more people. Vjekoslav "Maks" Luburić, commander-in-chief of all the Croatian camps, once bragged about Jasenovac's "efficiency." At a ceremony on October 9, 1942 - just a year after the camp was created - he said: "We have slaughtered here at Jasenovac more people than the Ottoman Empire was able to do during its occupation of Europe." The Ustaše general headquarters once published a pamphlet that said: "the concentration and labor camp in Jasenovac can receive an unlimited number of internees [prisoners]." Finally, Miroslav Filipovic-Majstorovic, once captured by Yugoslav forces, tried to minimize the crimes committed in Jasenovac by saying that during the three months that he ran the camp, 20,000 to 30,000 people died. In other sources, that three months' death toll is displayed as 40,000.
