Reich Security Head Office Referat IV B4, known as RSHA IV B4, was a sub-department of Germany's Reich Security Head Office (Reichssicherheitshauptamt or RSHA) and the Gestapo during the Holocaust. Led by SS-Obersturmbannführer Adolf Eichmann, RSHA IV B4 was responsible for "Jewish affairs and evacuation" in German-occupied Europe, and specifically for the deportation of Jews from outside Poland to concentration or extermination camps. Within Poland, the liquidation of the ghettos and transport of Jews was handled by the SS and local police departments.
Created after a reorganization of the RSHA in March 1941, RSHA IV B4 managed the categorization of Jews, the imposition of anti-Jewish legislation in the country concerned, the eventual removal of Jews from that country, and their deportation to a camp and usually the gas chamber. Unit IV B4 was also in charge of the Reich Association of Jews in Germany, which oversaw all Jewish organizations.
Jews were carried to the camps in freight trains that had to be booked and paid for. The Deutsche Reichsbahn (German state railway) charged a one-way fare for the deportees and a return fare for the guards. The RSHA was billed for trains carrying Jews.
