In early-twentieth-century Argentina, anarchist expropriators employed direct, violent means to fund their movement. They used the proceeds to bankroll the production of books, newspapers, and other forms of propaganda; to assist plans to spring their comrades from prison; and to support the families of those who remained behind bars or in early graves. Bayer tells the thrilling story of bank robberies, payroll heists, counterfeiting rings, and other “crimes” committed in the name of revolutionary justice—as well as the contentious, often bloody infighting among anarchists willing to take extreme measures to achieve their ideals.
