Today in Labor History March 18, 1918: U.S. authorities arrested Mexican anarchist Ricardo Flores Magón under the Espionage Act. They charged him with hindering the American war effort and imprisoned him at Leavenworth, where he died under highly suspicious circumstances. The authorities claimed he died of a "heart attack," but Chicano inmates rioted after his death and killed the prison guard who they believed executed him. Magon published the periodical “Regeneracion” with his brother Jesus, and with Licenciado Antonio Horcasitas. The Magonostas later led a revolution in Baja California during the Mexican Revolution. Many American members of the IWW participated. During the uprising, they conquered and held Tijuana for several days. Lowell Blaisdell writes about it in his now hard to find book, “The Desert Revolution,” (1962). Dos Passos references in his “USA Trilogy.”
