The battle of Carmen de Patagones (1827): an archaeological-historical approach to a fluvial-maritime conflict landscape using GIS spatial models
Main Article Content
Abstract
The battle of Carmen de Patagones was part of the war between the United Provinces of the Río de la Plata and the Empire of Brazil (1825-1828). This conflict took place between late February and early March 1827, and comprised several events in different locations of the Negro river coast, nowadays Province of Buenos Aires, Argentine Republic. In this article, the methodology used to assess the location of the coastal battery used to defend the mouth of this watercourse against the Brazilian warships is presented. With this aim, information from historical sources (travel journals, cartography, and artillery manuals) and digital elevation model were mainly used. This data was processed using the Geographic Information Systems and their multi-criteria analyses. These models were improved after the remains of the 19th- to early 20th-century pilot’s station were found on April 2021. The obtained results allowed planning a surveying strategy used for searching the remains of the defence battery.
