Rundstedt's Corps disintegrated in the wake of defeat and the German Revolution, but while most officers were demobilised, he remained in the Army, apparently at the request of General Wilhelm Groener, who assumed leadership of the shattered Army. He briefly rejoined the General Staff, but this was abolished under the terms of the Treaty of Versailles, signed in June 1919. In October Rundstedt was posted to the staff of Military District () V, based in Stuttgart, under General Walter von Bergmann. He was there when the attempted military coup known as the Kapp Putsch took place in March 1920. Bergmann and Rundstedt, like most of the Army leadership, refused to support the coup attempt: Rundstedt later described it as "a failure and a very stupid one at that." This was not an indication of any fondness for the Weimar Republic on Rundstedt's part – he remained a monarchist. It was a reflection of his view that Army officers should not interfere in politics, and should support the government of the day, whatever its nature: a view he was to hold firmly to throughout his career. He testified at the Nuremberg Trials in 1946: "We generals did not concern ourselves with politics. We did not take part in any political discussions, and we did not hold any political discussions among ourselves."
