Operation Zamość
The ethnic cleansing of Zamojszczyzna by Nazi Germany (German: Aktion Zamosc, also: Operation Himmlerstadt) during World War II was carried out as part of a greater plan of forcible removal of the entire Polish populations from targeted regions of occupied Poland in preparation for the state-sponsored settlement of the ethnic German Volksdeutsche. The operation of mass expulsions from Zamojszczyzna region around the city of Zamość (now in Lublin Voivodeship, Poland) was carried out between November 1942 and March 1943 on direct order from Heinrich Himmler.
