Rudolf Hess, Hitler's future deputy, who recently had moved to Munich and now lived in Elisabethstraße, close to the barracks in which Hitler resided… - Thomas Weber

Whatever his inner thoughts and intentions, Hitler now had to serve as a representative of his unit within the new Soviet regime. By his willingness to run for office as Bataillons-Rat, he had become even more significant cog in the machine of Socialism than previously had been the case. Hitler’s actions helped sustain the Soviet Republic.

[O]n surviving film footage of Eisner’s funeral we see Hitler with a few men from his unit walking behind Eisner’s coffin in the funeral procession of the Bavarian leader. We clearly see Hitler wearing two armbands: one black band to mourn the death of Eisner and the other a red armband in the colour of the Socialists revolution. Similarly, Hitler appears on one of Heinrich Hoffman’s photographs of the funeral process for Eisner.

Hitler’s undetermined political future becomes even less surprising if we bear in mind that the intellectual origins of Fascism share central tenets with the non-Marxist Left. According to one argument, despite its eventual collision with the conservative Right once Fascism tried to come to power, early Fascism had been in its promise, rather than in its eventual application, more socialist than capitalist, more plebeian than bourgeois.
