After landing in Italy, Galleani returned to publishing Cronaca Sovversiva. After Mussolini came to power in 1922, the anarchist was charged with sedition and sentenced to 14 months in prison. He was re-arrested in 1926, and sent again to the island of Pantelleria, then the island of Lipari, and finally to Messina. Later he was allowed to return to the Italian mainland, where he lived in the village of Caprigliola (Lunigiana) but the police surveillance continued. Galleani died of a heart attack at age 70 on November 4, 1931. Galleanist activities Galleani attracted numerous radical friends and/or followers known as "Galleanisti", including Frank Abarno, Gabriella Segata Antolini, Pietro Angelo, Luigi Bacchetti, Mario Buda also known as "Mike Boda", Carmine Carbone, Andrea Ciofalo, Ferrucio Coacci, Emilio Coda, Alfredo Conti, Nestor Dondoglio also known as "Jean Crones", Roberto Elia, Luigi Falzini, Frank Mandese, Riccardo Orciani, Nicola Recchi, Giuseppe Sberna, Andrea Salsedo, Raffaele Schiavina, Carlo Valdinoci, and, most notably, Nicola Sacco and Bartolomeo Vanzetti. Galleani and his group promoted radical anarchism by speeches, newsletters, labor agitation, political protests, secret meetings, and, above all, direct action. Many used bombs and other violent means to promote their political position, practices that Galleani actively encouraged but in which he apparently did not participate, except for writing the bomb-making manual La Salute è in voi!. Historians believe that Galleani's followers began their bombing attacks in 1914. Galleanists were involved in at least two bombings in New York after police forcibly dispersed a protest at John D. Rockefeller's home Kykuit near Tarrytown. Over the next several months, bombings took place at several New York City sites, including police stations, churches, and courthouses. On November 14, 1914, a bomb was placed in The Tombs police court, under the chair of Magistrate Campbell, who had sentenced an anarchist for inciting to riot. In January 1915, police uncovered a plot to blow up St. Patrick's Cathedral in New York, and a copy of La Salute è in voi! was found at a suspect's house. One Chicago-based Galleanist, chef Nestor Dondoglio, known by the alias Jean Crones, laced soup with arsenic in an attempt to poison some 100 guests, all figures in industry, business, finance, or law, at a banquet in 1916 to honor Archbishop Mundelein. J.B. Murphy, a doctor among the guests, furnished a hastily prepared emetic that induced vomiting. None of the guests died, though many suffered greatly. Police discovered
