Themes: War

Invited by Peruvian president Luis José de Orbegoso to help end a civil war in Peru, Santa Cruz leads a Bolivian army across the border. At Yanacocha near Cusco he defeats the forces of his old rival Agustín Gamarra, opening the way for a deep Bolivian intervention in Peruvian politics.

## Why it matters
The victory launched Santa Cruz's project of uniting Peru and Bolivia under his own leadership in a single Andean state.
