For years there have been intensive debates about Nazi Germany’s war of extermination between 1939 and 1945. What has been lacking so far is a comprehensive account of the war carried out by the German armed forces in Italy. The exact numbers and distribution of German military units are unknown and there are few details concerning the circumstances of killings and injuries in front line combats or partisan wars. Detailed research on memoirs and war logs has often uncovered deficiencies in these accounts. This data base is designed as a research tool for historians in this field as well as for institutional or private research for communal purposes. The data was assembled by Carlo Gentile (Cologne) between 2000 and 2004 on behalf of the German Historical Institute Rome. The data base includes more than 16,000 entries that were taken from contemporary sources and further edited. Sources were primarily provided by the “Deutsche Dienststelle” (formerly “Wehrmachtsauskunftsstelle”) as well as the department for military archives of the Federal Archive in Freiburg. The data base lists places in Italy (cities, communes, villages, hamlets, farm houses, junctions) where German troops were undoubtedly located between 1943 and 1945.
