Very rare occupation map of Königshütte (Chorzow) printed by OKW (Oberkommando der Wehrmacht). It's broken in several parts and repaired with adhesive type, but it's complete. Chorzów (German: Königshütte, Silesian: Chorzōw) is a city in Silesia in southern Poland, near Katowice. Chorzów is one of the central cities of the Upper Silesian Metropolitan Union - a metropolis with a population of 2 million. It is located in the Silesian Highlands, on the Rawa River (a tributary of the Vistula). On the day of the outbreak of World War II in September 1939, Chorzów was taken by Nazi Germany. Polish irregulars, mainly Silesian uprising veterans and Scouts, put up resistance to the regular German forces for three days, most of them were murdered in mass executions. Polish property was confiscated, and Chorzów (with the balance of Polish Silesia) was promptly re-incorporated into German Silesia. There were 2 satellite camps of Auschwitz in this city.
