Abstract
This scientific paper analyzes the materials of a collection containing documents on the crimes committed by the German and Romanian occupiers and their accomplices in the Mykolaiv region between 1941 and 1944. The documented acts of violence against civilians and prisoners of war, validated by the investigation, contribute to a broader understanding of crimes against humanity in Ukraine during the German-Soviet War (1941–1945). These records allow for a more precise assessment of the scale, forms, and methods of mass extermination and enable comparisons with crimes committed by Russian invaders in Ukraine today. Considerable attention is given to the articles by Valerii Vasyliev and Roman Podkur.
