The Gwardia Ludowa military wing of PPR (with which Parczew partisans aligned themselves, for the weapons), engaged in robberies and terror expeditions aimed at local domination over the competing political structures. On one occasion, the unit of Gwardia Ludowa commanded by Grzegorz Korczyński from Kraśnik County near Lublin, committed mass atrocities in the village of Ludmiłówka on 6 December 1942 killing dozens of Jews in retaliation for the PPR action in Grabówka against their own men. These murders were hushed up in Stalinist Poland by the Ministry of Public Security engaged in brutal persecution of the AK soldiers.
