Volksdeutscher Selbstschutz
Prior to the World War 2, the region partially overlapped with the Kosznajderia or "Koschneiderei" former ethnocultural region inhabited by a relatively secluded community of Catholic German settlers brought from the Prince-Bishopric of Osnabrück by the Teutonic Order State during its brief control of the area at the end the 14th century, who maintained their original culture (including clothing) and spoke Koschneiderisch, a distinct South-East-Pomeranian or Süd-Hinterpommersch dialect of Low German which preserved many features of Westphalian dialect of Middle Low German (spoken by the original pioneer founding settlers), itself heavily influenced by the Middle Dutch. Almost the entire population of Kosznajders fled or were expelled to Germany upon the end of the war, having cohabitated peacefully for centuries with their Polish, Kashubian or Jewish neghbours, before finally succumbing to Nazi German propaganda during the increasing hostilities of the German Reich towards Poland in the months preceding the impeding invasion, when a number of Kosznajders joined the Volksdeutscher Selbstschutz, participated in the preparation of Sonderfahndungsbuch Polen, or even played an active role in atrocities against Poles, such as the Rudzki Most massacre, a part of the larger genocidal "Intelligenzaktion Pommern".
