During the war between Brazil, Uruguay and Argentina against Paraguay (1865–1870), the Paraguayans deployed Congreve rockets in several battles including: Battle of the Riachuelo (June 11, 1865) when land-based rockets were used against Brazilian naval forces without success; Battle of Paso de las Cuevas (August 12, 1865) when the Paraguayans utilized artillery and rockets; combat of Corrales (January 31, 1866) when Paraguayan rockets were used against the Allied infantry and cavalry; Battle of Tuyutí (May 24, 1866) when Paraguayan forces used them to attack the advancing allied cavalry; battle of Yatayti Corá (July 10, 1866) where Paraguay used two launchers of 68-pound rockets; again in "Yatayti Cora" (January 20, 1867) when Paraguayan rockets caused a fire in the Argentinian camp. The Brazilian Navy employed them during the Battle of Curupayti (September 22, 1866), trying to destroy the reinforced Paraguayan trench field, but the rockets went short.
