The Battle of Viluma, also known as Battle of Sipe-Sipe, was a major battle in the South American wars of independence in which the United Provinces of the Río de la Plata (formerly the Spanish Viceroyalty of the Río de la Plata) were decisively defeated in Upper Peru (now Bolivia) by the Royal Army of Viceroyalty of Peru. The battle took place on November 29, 1815 on a plain west of Cochabamba, and resulted in the loss of Upper Peru for Buenos Aires. The area was reannexed by the Spanish Viceroyalty of Peru.^[1]
