One of the few English-language studies of the Sturmabteilung (SA), the Nazi Brownshirts whose street violence and ideological fervor enabled Hitler's rise to power in '20s and '30s Germany. During the Weimar era, they evolved from a fragmented group of far-right militias into a unified paramilitary squad who presented an ever-present threat to Hitler's enemies. Its early membership consisted largely of working class, urban Germans whose fanaticism bred interparty feuds, from renegade Walter Stemmens (who led an abortive SA coup to displace Hitler in the early '30s) to their leader, Ernst Rohm, who broke with Hitler over the latter's refusal to push for a "Second Revolution" after seizing power. The common narrative of the SA is that, after Hitler's rise to power, he no longer needed these fanatics' assistance, leading to the Night of the Long Knives in June 1934, where Nazi officials murdered Rohm and dozens of other Brownshirt leaders. Siemens argues this portrait is incomplete, if not misleading; while never as politically powerful after Rohm's death, the Brownshirts remained the most visible enforcers of fascist ideology in and outside of Germany. Their uniformed presence in towns and cities provided a constant reminder of the regime's beliefs and violence, whether in events like Kristallnacht or commonplace attacks on Jews, Communists and critics of the regime. Its leaders (from Viktor Lutze, the SA chief who constantly maneuvered to defend his group against Himmler's SS and other bureaucratic rivals, to Siegfried Kasche, who coordinated genocide in Croatia and other Balkan states) spearheaded Nazi plans for resettlement and Nazification of conquered territories. Brownshirts actively joined in the conquests, too, whether by enlisting in the Wehrmacht, forming separate military units of their own, or participating in the purges of Jews and Slavs behind the lines. Afterwards, SA veterans promoted an image of themselves as detached from the regime's atrocities and centers of power, allowing them to escape the scrutiny afforded the SS, or even the Wehrmacht in postwar Germany. Few historians, German or otherwise, have bothered to pushback against this myth; in doing so, Siemens provides a valuable addition to scholarship on the Third Reich.
