Vinnytsia massacre was a mass execution of between 9,000 and 11,000 people in the Ukrainian town of Vinnytsia by the Soviet secret police NKVD during the Great Purge or Yezhovshchina in 1937 – 1938 . Mass graves in Vinnytsia were discovered during the German occupation of Ukraine in 1943 . The investigation of the site first conducted by the international Katyn Commission coincided with the discovery of a similar mass murder site of Polish prisoners of war in Katyn . Because the Germans utilized this evidence of Communist terror to discredit the Soviet Union internationally , it became one of the better researched sites of the politically motivated NKVD massacres among many in Ukraine
