No. 13 of the circular "Do Not Yield," produced in Florence by a circle of intellectuals led by the young historian Nello Rosselli and one of the most forceful of the early clandestine anti-Fascist publications. It demanded much of its readers: "Chi riceve il bolletino è moralmente impegnato a farlo circolare" [Whoever receives this document is morally obligated to circulate it]. The Fascists tried to destroy all issues. A dozen years later Nello Rosselli and his brother Carlo, recovering in France from wounds he had received fighting in Spain in the International Brigade, were assassinated by French Fascists acting on Mussolini's orders. The story is the basis of the novel The Conformist by Alberto Moravia, cousin of the Rosselli brothers.
