Rosa crossed the borders towards her freedom with her sons Eugênio, Francisco, Flaubio and Domingos and “one still suckling in the breast.” When her masters, cattle breeders in Uruguaiana, Rio Grande do Sul, refused to grant her manumission, she and her family fled to the Uruguayan border. Rosa was part of a larger movement which saw many enslaved people fleeing from different areas of Rio Grande to the neighboring country and also to Argentina between the 1840s and 1870s.
