No part of the Nazi movement contributed more to Hitler's success than the Sturmabteilung (SA) - the notorious Brown Shirts. Bruce Campbell offers the first in-depth study in English of the men who held the three highest ranks in the SA. Organized on military lines and fired by radical nationalism, the Brown Shirts saw themselves as Germany's paramilitary saviors. By tracing the activities, both individual and collective, of these men's adult lives through 1945, Campbell shows where members acquired the experience necessary to build, lead, and administer the SA. These men were instrumental in creating the Nazi concept of "political soldiering, " combining military organization with political activism.
