The War between Argentina and Peru–Bolivian Confederation was an armed conflict that occurred between 1837 and 1839. Because it happened simultaneously when the Peru-Bolivian confederation was engaged in a parallel war against the Republic of Chile, in the so-called War of the Confederation, the first conflict referred here is often confused with the second. The war began on May 19, 1837  when the then in charge of managing foreign relations for the Argentine Confederation and governor of the Province of Buenos Aires, Juan Manuel de Rosas, declared war directly on President Andres de Santa Cruz, both for the Question of Tarija and its support for the Unitarian Party. The operations began in August 1837 when Bolivian confederate troops invaded most of the Province of Jujuy, the Puna de Jujuy and the north of the Province of Salta. Continuing with a series of combats and skirmishes between both forces, all of them without conclusive results.Robert L. Scheina "Latin America's Wars: The age of the caudillo, 1791-1899 - The Peru Bolivian Confederation" pág. 136 In May and June 1838, the Confederate army defeated Rosas's troops in a series of encounters, the most important of which was the Combate de Montenegro or Combate de la Cuesta de Coyambuyo, which in practice led to the Argentine withdrawal from the war that from then on he maintained a defensive posture, although the state of war continued until the victory of the Chilean-Peruvian restorative army at the Battle of Yungay, which put an end to the Peru-Bolivian Confederation. On December 28, 1836  Rosas wrote to the governor of Salta Felipe Heredia: 1) The war would not be against the peoples of Peru and Bolivia, but rather against Santa Cruz, who would be forced to evacuate Peru; 2) Santa Cruz would not be allowed to remove armies or armaments from Peru and the Bolivian army should be reduced to maintaining internal order; 3) Tarija would be restored to Argentina, Chile would receive compensation for Freire's pronouncement, and Argentina for the expenses of the war of independence and the unitary incursions; 4) Bolivia and Peru should grant Argentina and Chile favorable trade conditions and adjust limits with them. Portales was upset by the delay in the declaration of war by Rosas and did not accept to include in the alliance the restitution of Tarija nor the compensation for the damages caused by the Unitarians from Bolivia,because the Government of Chile had not participated in these matters. Consequently, the treaty of alliance was suspended, but a de facto alliance was agreed, so that Rosas would declare war on Santa Cruz and not on the Peruvian states.Historia Argentina: Unitarios y federales ( 1826-1841 ). pp. 264-265. Volumen 4 de Historia Argentina. Autor: José María Rosa. Editor: Editorial Oriente, 1841 On May 19, 1837  Rosas declared that "the Argentine Confederation is at war with the government of Santa Cruz, and its supporters," without waiting for the pronouncement of the other provinces. Santa Cruz had appointed Otto Philipp Braun as commander of operations in the south, seconded by Generals Francisco Burdett O'Connor, Sebastián Ágreda and Timoteo Raña. Braun's barracks were established in Tupiza where an army that did not exceed 2,400 men was concentrated, almost all of them from Chicheños and Tarijeños, distributed in the following units: 1st Battalion of “La Guardia”, 5th line, 6th “Socabaya”, 8th of "Nationals", with 300, 380, 700 and 600 infantry men respectively; Regiment "Guides de la Guardia" and Regiment 2º de "Nacionales", both cavalry with a total of 4 squadrons, 2 of them hunters, 1 cuirassiers and 1 guides. The artillery had a brigade with 4 pieces under the command of Commander García. On  24 of June 1837  the Battle of Montenegro occurs, in the vicinity of Padcaya. Paz thad to withdraw to Argentine territory, being continually harassed by Bolivian troops. In this battle the Bolivians captured 20 Argentine officers.David Marley "Wars of the Americas: a chronology of armed conflict in the New World, 1492 to the present"
