Wilhelm Groener
In the summer of 1919, the administration and command structures of the German armed forces were completely restructured. The "Oberste Heeresleitung" was dissolved in early July. Paul von Hindenburg and Wilhelm Groener, the highest-ranking officers, both resigned. In August, the Weimar Constitution came into force and Minister of Defence Noske became commander in chief of the new Reichswehr. The existing War Ministries of the individual German states (Bavaria, Saxony, Württemberg and Prussia) were dissolved or integrated into the new "Reichswehrministerium" in Berlin. On 13 September, the position of Prussian Minister of War was abolished and Reinhardt became commander of the "Reichswehrstelle Preußen" on 1 October. He expanded this position into that of "Chef der Heeresleitung", the highest-ranking military position within the landforces. He was promoted to General Major. Reinhardt's main tasks now became reducing the army's troop strength to 100,000 in accordance with the Treaty of Versailles and reorganising the army.
