Ituzaingó, Battle of

Battle of Ituzaingó, the most important contest in the war between the Brazilian Empire and the United Provinces of the Río De La Plata (1825–1828) over the territory referred to by some as the Provincia Oriental and by others as Cisplatine Province. In Brazil this battle is often known as the Passo do Rosário. Ituzaingó is located in present-day Argentina. The battle took place 20 February 1827 and ended in a decisive victory for the troops of Río de la Plata. The number of combatants is estimated at approximately 16,000. The Brazilian forces were slightly superior in numbers and more so in arms and supplies. General Carlos de Alvear commanded the troops of Río de la Plata, among whom figured 3,000 men from the Provincia Oriental, led by General Juan Antonio Lavalleja. The victory of the forces of Río de la Plata at Ituzaingó dealt a strong blow to Brazilian hopes of extending its territory to Río de la Plata. Brazil was further frustrated in this effort by the Preliminary Peace Pact of 1828, out of which was born the independent nation of Uruguay.
