Alexandre Gomes de Argolo Ferrão Filho was a Brazilian Marshal of the Balaiada and the Paraguayan War.

[1] Argolo is of Spanish descent as his descendants can trace their origins to the initial colonization of Brazil under Tomé de Sousa and they had historically settled in Salvador, Bahia.

[2] He entered military service on December 2, 1837, as a cadet within the 1st Artillery Battalion[1][3] and was promoted to Second Lieutenant by the next year.

During his service in the war, the Duke of Caxias ordered the Argolo Ferrão Battalion to construct the Grão-Chaco Road which would improve Brazilian navigation within the Gran Chaco.

Antônio Loureiro de Souza, referring to the Viscount's bravery, stated: The great Caxias with whom he served, held him in high regard, never getting tired of praising him on various orders of the day.
