The Expedición Libertadora del Perú (Liberating Expedition of Peru) was organized in 1820 by the government of Chile, with elements belonging to the Liberating Army of the Andes and to recently restored Army of Chile, whose target was to free the Viceroyalty of Perú from Spanish rule. The expedition was the continuation of the plan of liberation that General Bernardo O'Higgins and General José de San Martín conceived for the Spanish colonies of South America. While the Chilean government headed by Bernardo O'Higgins played a pivotal role in organizing the expedition, the control of the Chilean Squadron was given to Thomas Cochrane, 10th Earl of Dundonald and the control of the ground force relapsed into the Argentine General José de San Martín. The expedition managed to liberate parts of Peru.
