Hitler's speech of 30th January 1935, Domarus, "Hitler",Vol. 1: also Joseph Goebbels in a speech to the 1933 Reich Party Congress, The Race Question and World Propaganda', reproduced in a collection of his speeches, 'Signale der neuen Zeit'. During a commemorative address of 30th January 1937, in which Hitler boasted that the National Socialist revolution had 'not broken even a windowpane', he added significantly, 'Don't misunderstand me, however. If this revolution was bloodless that was not because we were not manly enough to look at blood' (Baynes, Speeches of Adolf Hitler).
