Before the Nazis came into power in early 1933, this political figure, in collaboration with the exiled Russian physiologist and specialist of specific methods of political propaganda, Sergei Chakotin (S.S.Chakotin, 1883-1973), created as new as active aggressive propaganda-techniques. The very slogan of Mierendorff and Chakotin was: "Whenever we will fight successfully against the Nazi - we must beat them within their own central political field: the political propaganda." Mierendorff called this specific fight against the Hitler-Goebbels-Goering-gang "the war of the symbols".

Chakotin later named it “the violant propaganda of non-violance”. The anti-fascist struggle in Germany as three-arrow campaigne 1931-32, a relevant political event of militant socialists, was also registered in other European countries like Denmark, France, and insular United Kingdom (“three cheers on the Three Arrows”).

The three-arrows campaigne had the ´theoretical´ basis in Mierendorffs concept of social democracy (1922) and his grounded analysis of the Nazi movement and its social dynamics (1930); it applied also features of the Russian behavioural concept of ´conditional reflexes´ (I.P.Pavlov) as well as imaginations of Russian vanguard artists (like El Lissitzkys poster 1920: “We´ll Beat the Whites With Our Red Wedge”). The three-arrow episode within traditional working class movement in the early 1930ies was not at all successful. Nevertheless Mierendorff and Chakotin regarded their political campaigne, and the methods applied, as a relevant political strategy for preventing Germany from civil war which was, in 1932, an impending doom in Germany.
