International outrage at a series of similar acts of violence committed by the Polish military ( Pinsk massacre ) and the civilian population ( Kielce pogrom ) against the Jews led to the appointment of an investigation commission by the United States President Woodrow Wilson in June 1919 . On 3 October 1919 , the commission led by Henry Morgenthau , Sr. published its findings . According to the Morgenthau Report , excesses in Lwów were " political as well as anti-Semitic in character " . At the same time , the Morgenthau Report cleared the Polish government of any responsibility for the events and attributed the casualties to " the chaotic and unnatural state of affairs " . Independent investigations by the British and American missions in Poland stated that there were no clear conclusions and that foreign press reports were exaggerated
