The freedman Gregorio Cosme Osorio’s extant letters from Madrid in 1795 are the focus of Chapter 6. They provide a direct perspective of a cobrero leader’s legal culture, his views on the case, and his activities as liaison between Madrid and El Cobre (including an alleged meeting with the king). Cosme’s missives from the royal court, which high colonial officials considered subversive, critiqued politics of the law in the colony and kept the cobreros abreast of the imperial edicts issued in Madrid in their favor which colonial authorities ignored. His liaison role during fifteen years was crucial to keep the case alive in the royal court.
