Abstract

In a rare example of how Humanities and Exact Science can come together in the same project, this study used technology to unravel the gaps in history and historical research to contextualize the content of confidential documents about the Canudos War (1896-1897). Cryptanalysis tools were used to decipher the text of four secret telegrams, held for over a century at the Army Historical Archives. In order to understand their content, it was necessary to consult documentary and bibliographic sources that allowed additional information to the encrypted reports about the failure of the third military expedition and what happened to the body of its leader, Colonel Moreira César.
