Nemmersdorf massacre
The Nemmersdorf massacre was a civilian massacre  perpetrated by Red Army soldiers in the late stages of World War II. Nemmersdorf (present-day Mayakovskoye, Kaliningrad Oblast) was one of the first prewar ethnic German settlements to fall to the advancing Red Army during the war. On 21 October 1944, Soviet soldiers killed many German civilians as well as French and Belgian POWs.

Incident
The 2nd Battalion, 25th Guards Tank Brigade, belonging to the 2nd Guards Tank Corps of the 11th Guards Army, crossed the Angerapp bridge and established a bridgehead on the western bank of the Rominte river on 21 October 1944. The German forces tried to retake the bridge, but several attacks were repelled by the Soviet tanks and the supporting infantry. During an air attack, a number of Soviet soldiers took shelter in an improvised bunker that was already occupied by 14 local men and women. According to the testimony of a seriously injured woman, Gerda Meczulat, when a Soviet officer arrived and ordered everybody out, the Soviets shot and killed the German civilians at close range. During the night, the Soviet 25th Tank Brigade was ordered to retreat across the river and take defensive positions along the Rominte. The Wehrmacht regained control of Nemmersdorf and discovered the massacre.

Evidence
Nazi German authorities organized an international commission to investigate, headed by the Estonian Hjalmar Mäe and other representatives of neutral countries, such as Francoist Spain, Sweden and Switzerland. It heard the report from a medical commission, which reported that all of the dead females had been raped (they ranged in age from 8 to 84). The Nazi Propaganda Ministry (separately) used the Völkischer Beobachter and the cinema news series Wochenschau to accuse the Soviet Army of having killed dozens of civilians at Nemmersdorf and having summarily executed about 50 French and Belgian noncombatant prisoners-of-war, who had been ordered to take care of thoroughbred horses but had been blocked by the bridge. The civilians were allegedly killed by blows with shovels or gun butts. 
 
The former chief of staff of the German Fourth Army Major General Erich Dethleffsen, testified on 5 July 1946 before an American tribunal in Neu-Ulm:

Karl Potrek of Königsberg, the leader of a Volkssturm company present when the German Army took back the village, testified in a 1953 report:

War-time propaganda 
At the time, the Nazi Propaganda Ministry disseminated a graphic description of the events to dehumanize Soviets in eyes of German soldiers. On the home front, civilians reacted immediately, with an increase in the number of volunteers joining the Volkssturm. More civilians, however, responded with panic and started to leave the area en masse.

To many Germans, "Nemmersdorf" became a symbol of war crimes committed by the Red Army and an example of the worst behaviour in Eastern Germany. Marion Gräfin Dönhoff, the post-war copublisher of the weekly Die Zeit, lived at the time of the reports in the village of Quittainen (Kwitany) in western East Prussia, near Preußisch Holland (Pasłęk). She wrote in 1962:

Re-investigation
After the 1991 fall of the Soviet Union, new sources became available and the dominant view among scholars became that the massacre had been embellished and actually exploited by Goebbels in an attempt to stir up civilian resistance to the advancing Soviet Army. Bernhard Fisch, in his book, Nemmersdorf, October 1944. What actually happened in East Prussia, concluded that liberties were taken with at least some of the photographs, some victims on the photographs were from other East Prussian villages, and the notorious crucifixion barn doors were not even in Nemmersdorf. Additionally, the writer Joachim Reisch, who also claimed to be witness to the events, placed the Soviet presence in Nemmersdorf to less than four hours of heavy fighting in front of the bridge, before pulling back to defensive positions.

Sir Ian Kershaw is among the historians who believe that the Soviet forces committed a massacre at Nemmersdorf, but the details and numbers are disputed. The German Federal Archives (Bundesarchiv) contain many contemporary reports and photographs by officials of Nazi Germany of the victims of the Nemmersdorf massacre. They hold evidence of other Soviet massacres in East Prussia, notably Metgethen. In the late 20th century, Alfred de Zayas interviewed numerous German soldiers and officers who had been in the Nemmersdorf area in October 1944, to learn what they saw. He also interviewed Belgian and French prisoners-of-war who had been in the area and fled with German civilians before the Soviet advance. De Zayas incorporated those sources into two of his own books: Nemesis at Potsdam and A Terrible Revenge.
