were also part of the viceroyalty, and began their push for autonomy during the conflict, becoming independent states afterwards. The vast area of the territory and slow communications led most populated areas to become isolated from each other. The wealthiest regions of the viceroyalty were in Upper Peru (modern-day Bolivia). Salta and Córdoba had closer ties with Upper Peru than with Buenos Aires. Similarly, Mendoza in the west had closer ties with the Captaincy General of Chile, although the

was isolated from all other regions. In the political structure most authoritative positions were filled by people designated by the Spanish monarchy, most of them Spanish people from Europe, also known as peninsulares, without a strong commitment for South American problems or interests. This created a growing rivalry between the Criollos, white people born in Latin America, and the peninsulares, Spanish people who arrived from Europe (the term "Criollo" is usually translated to English as "Creole", despite being unrelated to most other Creole peoples). Although they were all considered Spanish, and there were no legal distinctions between Criollos and Peninsulares, most Criollos thought that Peninsulares had undue influence in political matters.

, promoted desires of social change among the criollos. The full prohibition imposed by Spain to trade with other nations was also seen as damaging to the viceroyalty's economy. The population of Buenos Aires was highly militarized during the British invasions of the Río de la Plata, part of the Anglo-Spanish War. Buenos Aires was captured in 1806, and then liberated by Santiago de Liniers with forces from Montevideo. Fearing a counter-attack, all the population of Buenos Aires capable of bearing arms was arranged in military bodies, including slaves. A new British attack in 1807 captured Montevideo, but was defeated in Buenos Aires, and forced to leave the viceroyalty. The viceroy Rafael de Sobremonte was successfully deposed by the criollos during the conflict, and the Regiment of Patricians became a highly influential force in local politics, even after the end of the British threat. The transfer of the Portuguese Court to Brazil generated military concern. It was feared that the British would launch a third attack, this time allied with Portugal. However, no military conflict took place, as when the

The Revolution

The military conflict in Spain worsened by 1810. The city of

to discuss the fate of the local government. The military gave their support to the request, forcing Cisneros to accept. The discussion ruled the removal of viceroy Cisneros and his replacement with a government junta, but the cabildo attempted to keep Cisneros in power by appointing him president of such junta. Further demonstrations ensued, and the Junta was forced to resign immediately. It was replaced by a new one, the Primera Junta. Buenos Aires requested the other cities in the viceroyalty to acknowledge the new Junta and send deputies. The precise purpose of these deputies, join the Junta or create a congress, was unclear at the time and generated political disputes later. The Junta was initially resisted by all the main locations around Buenos Aires: Córdoba, Montevideo, Paraguay and the Upper Peru. Santiago de Liniers came out of his retirement in Córdoba and organized an army to capture Buenos Aires, Montevideo had naval supremacy over the city, and Vicente Nieto organized the actions at the Upper Peru. Nieto proposed to José Fernando de Abascal y Sousa, viceroy of the Viceroyalty of Peru at the North, to annex the Upper Peru to it. He thought that the revolution could be easily contained in Buenos Aires, before launching a definitive attack. Buenos Aires was declared a rogue city by the Council of Regency, which appointed Montevideo as capital of the viceroyalty of the Río de la Plata, and Francisco Javier de Elío the new viceroy. However, the May Revolution was not initially separatist. Patriots supported the legitimacy of the Juntas in the Americas, while royalists supported instead the Council of Regency; both acted on behalf of Ferdinand VII. All of them believed that, according to the

Armed conflict

The Primera Junta sent military campaigns to the viceroyalty, in order to secure support to the new authorities and retain the authority held as the capital of the viceroyalty. The victories and defeats of the military conflict delimited the areas of influence of the new United Provinces of the Río de la Plata. With the non-aggression pact arranged with Paraguay early on, most of the initial conflict took place in the north, in Upper Peru, and in the east, in the Banda Oriental. In the second half of the decade, with the capture of Montevideo and the stalemate in Upper Peru, the conflict moved to the west, to Chile.Camogli, pp. 32–33


Initial campaigns

The first two military campaigns ordered by the revolutionary Junta in Buenos Aires were launched against Cordoba, where former Viceroy Santiago de Liniers organized a counter-revolution, and the Intendency of

, which did not recognize the outcome of events at the May Revolution. However, the improvised army gathered by Liniers at Cordoba deserted him before battle, so the former Viceroy attempted to flee to the Upper Peru, expecting to join the royalist army sent from the Viceroyalty of Peru to suffocate the revolution at Buenos Aires. Colonel Francisco Ortiz de Ocampo, who led the patriot army, captured Liniers and the other leaders of the Cordoba counter-revolution on 6 August 1810, but, instead of executing them as he was instructed, he sent them back to Buenos Aires as prisoners. As a result, Ocampo was demoted and Juan José Castelli was appointed as the political head of the army. On 26 August, Castelli executed the Cordoba prisoners and led the Army of the North towards the Upper Peru. * First Upper Peru campaign (1810–1811) After securing the loyalty of the northwestern Provinces to the May Revolution through elections of representatives to the Junta in Buenos Aires, Castelli sent General

Thus, this campaign ended in failure as well from a military point of view; however, some months later, inspired on the Argentine example, Paraguay broke its links with the Spanish crown by declaring itself an independent nation. *First Banda Oriental campaign (1811)


Renewed offensives

The undesired outcomes of the Paraguay and Upper Peru campaigns led the Junta to be replaced by an executive Triumvirate in September 1811. This new government decided to promote a new campaign to the Upper Peru with a reorganized Army of the North and appointed José de San Martín, a veteran of the Napoleonic Wars who had recently arrived from Spain, as lieutenant colonel. San Martín was ordered to create the professional and disciplined cavalry unit known as Regiment of Mounted Grenadiers ( es, Granaderos a caballo). * Second Upper Peru campaign (1812–1813) General Manuel Belgrano was appointed as the new commander of the Army of the North. Facing the overwhelming invasion of a royalist army led by General Pío de Tristán, Belgrano turned to scorched-earth tactics and ordered the evacuation of the people of

and Salta, and the burning of anything else left behind to prevent enemy forces from getting supplies or taking prisoners from those cities. This action is known as the Jujuy Exodus. Turning against the Triumvirate orders, however, Belgrano decided to fight the royalists at Tucumán, obtaining a great victory and then decisively defeating the royalist army at the Battle of Salta, in northwestern Argentina, forcing the bulk of the royalist army to surrender their weapons.

The Battle of San Lorenzo ended further Spanish raids on the west bank of the Paraná river and the Triumvirate awarded San Martín the rank of general. The Granaderos unit was instrumental in the

for that role. One of the first actions of Posadas was to create a naval fleet from scratch, which was to be financed by Juan Larrea, and appointed William Brown as lieutenant colonel and chief commander of it, on March 1, 1814. Against all the odds, on 14 May 1814 the improvised patriot navy engaged the Spanish fleet and defeated it three days later. This action secured the port of Buenos Aires and allowed the fall of Montevideo, which could not stand the siege any more, on 20 June 1814.


The march towards Independence

The fall of Montevideo eliminated the royalist menace from the Banda Oriental and meant the actual end of the Spanish Viceroyalty of the Río de la Plata. Soon afterwards, William Brown was awarded the rank of admiral, and Carlos María de Alvear, who was put in charge of the siege of Montevideo just a few days before the surrender of the city, succeeded his uncle Gervasio Posadas as the Supreme Director of the United Provinces, on January 11, 1815. Alvear, however, was resisted by the troops, so he was quickly replaced, on April 21, by

(1815) :In 1815, the Northern Army, unofficially commanded by José Rondeau, started another offensive campaign in the Upper Perú, without the formal authorization of Supreme Director Álvarez Thomas. Lacking official support, however, the army was faced with anarchy. Moreover, soon after it would lose as well the aid of the Provincial Army of Salta, commanded by Martín Miguel de Güemes. After the defeats of Venta y Media (October 21) and Sipe-Sipe (November 28), the northern territories of the Upper Peru were effectively lost to the United Provinces. However, the Spanish Army could not advance further south as they were successfully stopped at Salta by the Güemes ''guerrillas'' from then on. The unsuccessful outcome of the third Upper Peru campaign would spread rumors in Europe that the May Revolution was over. Furthermore, King Ferdinand VII was restored to the Spanish throne on 1813, so an urgent decision was needed regarding the political status of the United Provinces. On July 9, 1816, an assembly of representatives of the Provinces (including three Upper Peru departments but excluding representatives from Santa Fe, Entre Ríos, Corrientes and the Banda Oriental, united into the Federal League) met at the Congress of Tucumán and declared the Independence of the United Provinces in South America from the Spanish Crown, with provisions for a national Constitution.


Army of the Andes (1814–1818)

In 1814, General José de San Martín had taken command of the Army of the North to prepare a new invasion of the Upper Peru. However, he quickly resigned as he foresaw yet another defeat. Instead, he developed a new strategy to attack the Viceroyalty of Perú through the Captaincy of Chile, inspired on the writings of Sir Thomas Maitland, who was quoted as saying that the only way to defeat the Spanish at Quito and Lima was attacking Chile first. San Martín asked to become the Governor of the

Installed in the city of Mendoza, San Martín reorganized the ''Granaderos'' cavalry unit into the Army of the Andes, which he created out of patriots from both the United Provinces and exiles from Chile. In early 1817, San Martín led the crossing of the Andes into Chile, obtaining a decisive victory at the battle of Chacabuco on February 17, 1817, and took

, and advanced towards the capital. San Martín then turned to scorched earth tactics and ordered the evacuation of Concepción, which he thought was impossible to defend. On 18 February 1818, the first anniversary of the battle of Chacabuco, Chile declared its independence from the Spanish Crown. On March 18, 1818, Osorio led a surprise attack on the joint Argentine-Chilean army, which had to retreat to Santiago, with heavy losses. In fact, among the confusion, Supreme Director O'Higgins was thought to be killed, and panic seized the patriot camp. Crippled after his defeat at Cancha Rayada, O'Higgins delegated the command of the troops entirely to San Martín in a meeting on the plains of Maipú. Then, on April 5, 1818, San Martín inflicted a decisive defeat on Osorio in the

, after which the depleted royalists retreated to Concepcion, never again to launch a major offensive against Santiago. The Chile campaign is generally considered to be the conclusion of the Argentine War of Independence, as the further actions of the United Army into Peru were carried on under the authority of the Chilean government, not the United Provinces. However, defensive actions continued to be carried on in the northern frontier of the United Provinces until the 1825 Battle of Ayacucho, which ended the royalist threat from the Upper Peru. The uprising of San Martin's army in Peru took place and they were passed en bloc to the Spanish army, except for a squadron of horsemen of the Granaderos that did not pass, the fact meant the disappearance of the forces taken to Peru by General José de San Martín, so the Argentine historian Bartolomé Mitre wrote: "being thus dissolved by the mutiny and treason the memorable Army of the Andes."
