The Nemmersdorf massacre was an event during World War II in which soldiers of the Red Army killed many civilians. During the war, Nemmersdorf was a village in East Prussia (it is now called Mayakovskoye, in Kaliningrad Oblast). The people living there were ethnic Germans. It was captured by the Red Army in October 1944. On 21 October, the Russian soldiers shot and killed women and children. The total number killed is not known: reports talk of between 50 to 100 people. The event has been labelled a war crime.
