Manuel Belgrano's operations: Paraguay Expedition, Jujuy Exodus and the Battle of Salta (1810–1813)

  1. Primera Junta launches the Paraguay campaign

    Labels: Primera Junta, Manuel Belgrano, Paraguay campaign

    After the May 1810 revolution in Buenos Aires, the new government (the Primera Junta) sought recognition from other former viceroyalty regions, including Paraguay. It sent a force under Manuel Belgrano to try to bring Paraguay into the revolutionary cause, using a mix of political outreach and military pressure. This decision opened a new front that would shape Belgrano’s early wartime reputation.

  2. Belgrano crosses the Paraná into Paraguay

    Belgrano’s expedition advanced north and crossed the Paraná River into Paraguayan territory, aiming to move toward Asunción. The campaign depended on gathering local support and moving supplies through difficult terrain and river routes. The crossing marked the point of no return from political pressure to direct military operations.

  3. Belgrano defeated at the Battle of Paraguarí

    Belgrano’s force fought Paraguayan defenders near Paraguarí and was defeated, forcing a retreat southward. The outcome showed that Paraguay’s authorities and militias would not be easily compelled to accept Buenos Aires’ leadership. The battle also weakened the expedition’s momentum and increased the campaign’s dependence on reinforcements and diplomacy.

  4. Tacuarí defeat ends Belgrano’s Paraguay expedition

    Belgrano made a defensive stand near the Tacuarí River but suffered a second major defeat. After the battle, he negotiated terms that allowed his remaining troops to withdraw, effectively ending the campaign. The failure meant Paraguay would not be incorporated by force into the Buenos Aires-led revolution.

  5. Belgrano takes command of the Army of the North

    With royalist pressure rising from Upper Peru (today largely Bolivia), Belgrano was assigned to lead the northern patriot army (often called the Army of the North or Auxiliary Army of Peru). He assumed command during a period of low morale and shortages after earlier setbacks. This transfer shifted him from the Paraguay front to the war’s most dangerous invasion route into the Río de la Plata heartland.

  6. Belgrano rebuilds the army base at Jujuy

    Belgrano established headquarters in San Salvador de Jujuy to reorganize battered forces and strengthen discipline. The strategic problem was urgent: royalist troops were advancing down the northern corridor toward Jujuy and Salta. This rebuilding phase set the conditions for later decisions to retreat, deny supplies to the enemy, and then counterattack.

  7. Jujuy Exodus begins under scorched-earth orders

    Facing a stronger royalist advance, Belgrano ordered a mass civilian evacuation from Jujuy while destroying or removing supplies that could aid the enemy. This scorched-earth retreat—later called the Jujuy Exodus—moved people and resources south toward Tucumán. The exodus aimed to slow the royalists, preserve the patriot army, and prevent a decisive defeat in the north.

  8. Combat of Las Piedras boosts patriot morale

    During the withdrawal, Belgrano’s troops defeated an advancing royalist detachment at the Las Piedras River. Although smaller than the major battles that followed, it helped restore confidence after months of retreat and loss. The action supported Belgrano’s case that the army could still fight effectively if it chose the right moment and ground.

  9. Belgrano fights at Tucumán despite retreat orders

    Belgrano chose to stop retreating and defend Tucumán, even though authorities in Buenos Aires had ordered continued withdrawal. Over two days of fighting, his smaller force defeated the royalist army and halted the invasion into the interior. The victory changed the campaign’s direction from retreat to pursuit and made a follow-up offensive possible.

  10. Belgrano advances to recover Salta and Jujuy

    After Tucumán, Belgrano reorganized and moved north to push royalist forces back. The campaign aimed to regain key cities and secure the frontier against renewed attacks from Upper Peru. This advance set up the decisive confrontation near Salta.

  11. Belgrano wins the Battle of Salta

    Labels: Battle of, Manuel Belgrano, P o

    Belgrano’s Army of the North defeated the royalist forces under Pío de Tristán near Salta, capturing large numbers of prisoners and securing a major battlefield success. This victory followed Tucumán and confirmed that the northern defense strategy—retreat, deny resources, then counterattack—could work. It also temporarily pushed the royalist threat away from Argentina’s northwest provinces.

  12. Royalist invasion route disrupted after Salta

    Labels: Royalist retreat, Jujuy safety, Upper Peru

    With the royalist army defeated and driven back toward Upper Peru, the immediate danger to Jujuy and Tucumán eased. The campaign’s outcome highlighted a clear arc: the failed attempt to compel Paraguay (1810–1811) contrasted with a successful defensive-offensive cycle in the northwest (1812–1813). Belgrano’s operations during these years became a key early foundation for sustaining the wider independence struggle in the Río de la Plata.
