by Nazi Germany, such as the Reichsgau Wartheland, the Reichsgau Danzig-Westpreußen, and the Polish General Government. In 1941 postal codes were introduced. The Feldpost military mail organisation of the Wehrmacht not only served Army, Luftwaffe and Kriegsmarine service members, but also SS-Verfügungstruppen, Waffen-SS and Reichsarbeitsdienst members in the field, becoming the general postal authority of the occupied territories. Deliveries were more and more affected by the advance of Allied troops from January 1945 on. The Reichspost finally ceased to function with the German Instrument of Surrender on 8 May. The last Reichspostminister Julius Dorpmüller, a member of the Flensburg Government, was arrested two weeks later, and governmental authority was officially taken over by the Allied Control Council with the Berlin Declaration of 5 June. Successors The Reichspost was initially replaced by Allied-controlled postal authorities that provided mail services in the occupation zones. From 1947 a united agency served the British-American Bizone area. With the emergence of two German states, the Deutsche Bundespost (German federal post office) was established in West Germany, and the Deutsche Post in East Germany. In addition, there was a separate Deutsche Bundespost Berlin for West Berlin, as well as the Saar postal authority (1947–1956). After the reunification of Germany in 1990, the state-owned Bundespost continued to function as the sole provider of postal services until 1995, when the postal, telecommunications, and banking divisions were spun off as separate entities. The Deutsche Bundespost eventually became Deutsche Post AG, a share holding company, later reintegrating the Postbank, and Deutsche Telekom. Other use Between 1894 and 1938, a daily newspaper called Reichspost was issued in Vienna, Austria. During the Second World War there was an additional use for the postal vans: "01.05.1942 Transfer of Postschutz in the SS (see Gottlob Berger), shortly after that also the 'remote power mail' ('front help of the Deutsche Reichspost') used as 'SS power driving season'. During 1942, these buses were used for transporting psychiatric patients to the gasification facilities of [the] T-4 euthanasia program."
