Heinz Guderian presides the German–Soviet military parade in Brest-Litovsk (now Brest, in Belarus), 22 September 1939. At his right is Generalleutnant Mauritz von Wiktorin -later discharged from the Army after the 20 July Plot- and at his left, Soviet tank commander Semyon Moiseevich Krivoshein. The building shown is nowadays the Brest Regional Executive Committee, located in Lenin St., in the city center. The 22th day of September, a joint parade of German and Soviet troops paraded in the occupied Polish town of Brest. The operation was in reality a show of strength before the Nazi high command ordered the mobilisation of its forces behind the new established German-Sovier frontier signed under the Molotov–Ribbentrop Pact.
