In 1598, Mapuche warriors began destroying Spanish settlements in present-day Chile founded by conquistador Pedro de Valdivia. When Villa Rica, one of the last strongholds, fell in 1602, only twenty-four of its five hundred inhabitants survived—thirteen of them women. By 1610, some captives had been freed, and the surviving men testified in legal proceedings against former Governor Alonso de Rivera. One charge concerned his exoneration of Captain Francisco Hernández de Ortiz, who failed to rescue Villa Rica despite being provided with troops and resources. Nevertheless, the all-male testimonies were not enough to convict him. In response to this failed justice and the limitations of official historical narratives, Chilean writer Carmen Gloria López, in La venganza de las cautivas (2018) [The Revenge of the Captives], reimagines archival records to foreground the voices of women erased from historical narratives. This chapter argues that La venganza functions as a multi-layered adaptation, exposing how legal and historical texts are themselves constructed narratives. By adapting the history of a trial, López not only recovers marginalized perspectives but also reshapes the production of historical knowledge, offering a more inclusive view of the past and expanding the critical possibilities of adaptation studies in Latin American literature.
