During the Communist crackdown in Poland after World War II, most of the history related to the Polish-Soviet War and the Blue Army was censored, distorted and repressed by the Soviet authorities. Anti-Jewish violence Throughout the fighting on the Ukrainian front, soldiers from the Blue Army assaulted local Jews, believing that some of them were cooperating with Poland's enemies. In eastern Galicia this included fighting a Jewish battalion of the Ukrainian Galician Army under the leadership of Solomon Leinberg. On 27 May 1919 a soldier by the name of Stanisław Dziadecki who served in one of the Blue Army's rifle divisions in Częstochowa, was shot and wounded while on patrol. A Jewish tailor was suspected of the shooting, and was promptly executed by Haller's soldiers and accompanying civilians, who proceeded to loot Jewish homes and businesses, killing 5-10 Jews and injuring several dozen more.

Polish police and regular army soldiers were occasionally able to restrain Haller's troops. According to Howard Sachar, in the year and a half prior to the Blue Army's arrival, the total number of Jewish casualties in the region was between 400 and 500; Haller's troops' violence caused this number to double. The Morgenthau Report estimated that the total number of Jews killed as a result of actions made by the Polish military (including the Blue Army) did not exceed 200–300. As a result of the Blue Army's activities, General Haller's visit to the United States was met with protests from American Jewish and Ukrainian communities. Tadeusz Piotrowski wrote that in most cases it's impossible to disentangle gratuitous antisemitism from commonplace looting and soldier brutality. He claims that the term "pogrom" in the accepted sense of the deliberate killing of Jewish civilians could not be applied to the great majority of the incidents in which the Blue Army was involved. Causes According to Alexander Prusin there were a number of causes for the anti-semitic acts of the Polish forces. Socioeconomic tensions regarding land reforms and conflation of Jews with the landed class led to the feelings of hostility. Also, the lack of appropriate
