This is one of those widely repeated things that coincidentally is never backed up by any numerical evidence whatsoever. Bolsheviks, per modern historical analysis, killed a total of less than 20 anarchists in the entire Spanish Civil War, and at least some of those because a spy in Nazi Germany called Harro Schulze-Boysen confirmed a Nazi plot to generate an anarchist insurrection in Barcelona to weaken the Republic's defenses. You tell me to read a book: well, point me towards a historiographical analysis of the Spanish Civil War pointing out NUMERICALLY HOW MANY anarchists were actually repressed by the communists.
Then simply tell me: which book can I read that details a numerical analysis of this repression, because I've asked several anarchists and never got a response.
