Berlin sent in the military – called the "White Guards of Capitalism" by the communists. On 3 April 1919, Hitler was elected as the liaison of his military battalion and again on 15 April. During this time he urged his unit to stay out of the fighting and not to join either side. The Bavarian Soviet Republic was officially crushed on 6 May, when Lieutenant General Burghard von Oven and his forces declared the city secure. In the aftermath of arrests and executions, Hitler denounced a fellow liaison, Georg Dufter, as a Soviet "radical rabble-rouser." Other testimony he gave to the military board of inquiry allowed them to root out other members of the military that "had been infected with revolutionary fervor." For his anti-communist views he was allowed to avoid discharge when his unit was disbanded in May 1919. In June 1919, Hitler was moved to the demobilization office of the 2nd Infantry Regiment.

The DAP had been formed by Anton Drexler, Karl Harrer and others, through amalgamation of other groups, on 5 January 1919 at a small gathering at the restaurant Fuerstenfelder Hof in Munich. While he studied the activities of the DAP, Hitler became impressed with Drexler's antisemitic, nationalist, anti-capitalist and anti-Marxist ideas.
