I saw this totally unknown film in a program dedicated to silent movies from Latin America in the Argentine cinematheque maybe some ten years ago, so I don't remember a lot about it (except that I like it). The movie dramatizes the last Indian uprising in Argentina, which happened in the north of the country, in the Chaco region, in the early 1900s. It was easily defeated by the Argentine troops, as expected. But what interested me when I saw it were certain dramatic devices not seen in cinema until decades later. For example, the very first scene shows the writer director writing the script of the movie. Then he is congratulated by an official of the province where the action took place for dramatizing these events. After that, the action takes place very much in the form of a southern (that is, a western set in South America). I don't remember much about the rest of the movie, except that it seemed somewhat sympathetic to the plight of the Indians, living in extreme poverty, which I don't think it was the characteristic view of the elites of the time (of which the director belong, of course).
