During the Polish-Soviet War , Mayor Łuczyński was a commanding officer of Polish troops in the frontline city of Pinsk , whose population was overwhelmingly Jewish . On 5 April 1919 after receiving numerous reports about planned attacks on the Polish army , and even on him personally , he gave the orders for what became known later as the Pinsk massacre , where 35 local Jewish members were executed without trial one hour after being arrested and accused of being Bolshevik plotters . The Jews , attending a local meeting that includes a number of leaders of the local Jewish community , were meeting to discuss distribution of financial and food relief , including aid for Passover . Narbut-Łuczyński , however , interpreted the meeting as a gathering of subversives planning a rebellion . The incident gained international notoriety . An investigation into the massacre was called by President of the United States Woodrow Wilson . Henry Morgenthau Sr. , at the time a senior adviser , and formerly the U.S. ambassador to the Ottoman Empire , was appointed to head the investigation and described Major Łuczyński as “ incredibly stupid . ” According to William W. Hagen Łuczyński " embodied military anti-Jewish paranoia , discovering in trivia malevolent design and finding himself in a numerous throng of unfriendly foreign-speaking Jews , high fearful of ambush "
