Also on this subject, Hitler later remarked: 'He would have his security men at rallies haul out political opponents so roughly that the opposition press which otherwise would have remained silent about the rallies ended up reporting the physical injuries at NSDAP rallies and thus drew attention to them' (Picker, tischgesprache). A vivid supplement to this is supplied by the memoirs of Hans Kallenbach, a member of the 'Stosstrupp Adolf Hitler 1923'. it says there of 'the men of the shock troop': 'All false sense of fair play and treading softly were alien to them. They remained faithful to might makes right, the old law of the club, and when hard pressed they were inhibited by no commandment. .. When Josef Berchthold or his deputy Julius Schreck blew the whistle and the command "Shock troop - to the attack! Left, right, step out, forward, march !" called us to action, the fur started to fly and in minutes the streets and squares were swept clean of opponents. We always played rough when we were let loose, when Berchthold, Schreck and Maurice let go so that the sparks flew.' (Kallenbach, Mit Adolf Hitler auf der Festung Landsberg.)
