A chronological account traces the emergence of anarchist agitation in America through the events that culminate in the Haymarket bombing in Chicago, documenting alleged conspiracies, police investigations, arrests, and the detailed courtroom proceedings. It presents evidence and counterarguments offered by prosecution and defense, witness testimony including undercover operatives, jury selection and instructions, verdicts, motions and appeals, and the ultimate executions and final letters of the condemned. The narrative situates these legal events within broader labor, political and social tensions, and includes documentary excerpts, trial costs, petitions for clemency, and episodes of penitence and suicide among prisoners.
