In his account of the incident, Paul Bernard claimed that the friendly fire incident caused 10,000 casualties;[4] however, he provided no source for this claim.[5] Neither the Austrian war archives' records nor those who have examined them corroborate Bernard's claim.[6] Bernard's account of the war has been dismissed as inaccurate.[7] Nevertheless, Bernard's claim of 10,000 casualties was repeated by Geoffrey Regan,[8] but it has also been dismissed as "extremely exaggerated".[9]
