Rudnia Łęczyńska was a Polish village with about 300 inhabitants during the Second World War. In April 1943, a detachment of German gendarmerie and Ukrainian police pacified the village, murdering about 200 people. The pretext for the pacification action was a report that the Poles were collaborating with Medvedev's Soviet partisans. The victims were buried in a common grave, which was a large pit dug on the order of the executioners before the execution began.

On the common grave of the murdered, the surviving inhabitants erected a cross. After several years, the cross fell over. The Soviet authorities then placed an obelisk with a star on the grave. The grave is located by the roadside, fenced off with a wooden fence more than a metre high, measuring 5 x 2 m, with evenly planted decades-old pine trees around it. The inscription (in Ukrainian) is painted on the obelisk. The inscription (translated into Polish) reads: "Here were buried the inhabitants of Rudni Łęczyńska / who became victims of the German fascists in 1943... [further part of the inscription is illegible]".
