"In the company of his old Italian friend Enrico Arrigoni, and urged on by him, Ferro commenced “to write several articles about the Cuban reality” which, with the help of Arrigoni’s translations, were published in the anarchist press of France, Italy, Mexico, and Argentina. According to Ferro, “In the majority of our milieus [these articles] were received with displeasure,” owing to the “enthusiasm” with which the Cuban Revolution had been received in them. But in other cases anarchists rallied to the Cuban libertarian cause. Reconstruir (“To Reconstruct”) in Buenos Aires, whose publishing house, Colectivo, fully identified with the Cuban anarchists, published all of Ferro’s works."Frank Fernández.
