Battle of Tucumán
The Battle of Tucumán was a battle fought on 24 and 25 September 1812 near the Argentine city of San Miguel de Tucumán, during the Argentine War of Independence. The Army of the North, commanded by General Manuel Belgrano, defeated the royalist troops commanded by General Pío de Tristán, who had a two-to-one advantage in numbers, halting the royalist advance on Argentina's northwest. Together with the Battle of Salta, on 20 February 1813, the victory at Tucumán allowed the Argentine troops to reaffirm the borders under their control.
