Written by Lucio V. Mansilla

"In 1868, at the end of the presidency of Mitre, he enthusiastically supported the candidacy of Sarmiento who rewarded him by appointing him as colonel and Commander of Borders in Rio IV province of Córdoba. There he made his campaign against the aborigines that will be immortalized in his work An excursion to the Ranqueles Indians. The work was published in installments in the newspaper La Tribuna throughout 1870. Five years later she would be awarded the first prize of the International Geographical Congress of Paris." – Philip Pigna
