The summer of 1920 was marked by escalating tensions on the borders of the German Reich. In the Rhineland, a neutral zone per the Versailles Treaty, the revolutionary uprising after the failed Kapp Putsch was put down with the help of the army and the Freikorps. In Upper Silesia, the conflict between Poland and Germany was escalating into a proxy war. And all that while the German government was negotiating the payments of reparations at the Spa Conference.
