According to Ukrainian historian Yaroslav Tsaruk (Ярослав Царук), who commented on data collected by Siemaszkos, the number of ethnic Poles given by them, in some of the villages he is familiar with, does not correspond with his Ukrainian research. According to Tsaruk, Siemaszkos included in the number of Polish citizens also those who emigrated before the commencement of hostilities according to him, and included population points which were not administrative units, thus enlarging the number of Polish victims of ethnic cleansing while minimizing the Ukrainian casualties. Tsaruk claims that although according to Siemaszkos 1,915 Poles died in the hands of Ukrainian Nationalists in the area of Volodymyr, according to him – only 430. Siemaszkos in their own monograph replied to this kind of criticism by stating that claims made by Tsaruk are based on statements made by Ukrainian villagers half a century after the war ended, therefore the discrepancies in what is being said by the locals can be "explained by psychological defense mechanisms".

Another Ukrainian historian, Ihor Ilyushin, echoed Tsaruk's observations and questioned whether Siemaszkos approach, based on testimony from one side, can be truly objective – wrote Canadian historian David R. Marples in Heroes and villains. Marples quoted Ilyushin as saying that because Władysław Siemaszko was a participant in the conflict he is not a credible witness. However, Marples also noted, that Ilyushin failed to reach a reasonable conclusion in his article and made no distinction between Ukrainian atrocities committed against officials and innocent civilians; men, women and children.
