Passage 2:As the Treaty of Versailles came into force on 10 January 1920, the German government had to drastically reduce the headcount of its regular armed forces, and dissolve paramilitary units like the right-wing Freikorps. Consequently, the German Reichswehrminister (defence minister) Gustav Noske ordered the dissolution of the Freikorps Marinebrigaden "Ehrhardt" and "Loewenfeld". The highest ranking general of the Reichswehr, Walther von Luttwitz refused to comply, which resulted in what became known as Kapp Putsch or Luttwitz-Kapp-Putsch. On 13 March 1920, the right-wing Marinebrigade Ehrhardt led by von Luttwitz marched into Berlin, occupied the government buildings and installed Wolfgang Kapp as new chancellor, calling for a return of the monarchy. To restore order, Noske then asked Hans von Seeckt, who at the time was the head of the Truppenamt im Reichswehrministerium, to order the regular army, the "Transitional Reichswehr", to put down the putsch. Von Seeckt and the other senior commanders with the exception of General Walther Reinhardt refused and the government was forced to flee from Berlin.
