Battle of Tumusla

This battle was fought on 1 April 1825, near the village of Tumusla (Potosí), in the current territory of Bolivia.

After the decisive defeat of the main royalist armies in the Battle of Ayacucho in Peru, on 9 December 1824, and the capture of Spanish Viceroy José de la Serna e Hinojosa, the only remain royalist army on the continent was that of Pedro Antonio Olañeta in Upper Peru (today's Bolivia).

Other versions claim that the importance of the battle was later diminished by Sucre, because he actually failed to defeat and capture Olañeta.

[3] This battle of the Bolivian war of independence was the last engagement in an open field by regular armies in South America.

After the battle Antonio José de Sucre, who had reached Potosí, called a congress of Upper Peru and saw the creation of Bolivia as a new independent nation on 6 August 1825.
