United Liberating Army of Peru

The United Liberating Army of Peru (Ejército Unido Libertador del Perú),   known during the last years of the war as the United Peruvian–Colombian Liberating Army of Peru (Ejército Unido peruano colombiano Libertador del Perú),  was an army during the Peruvian War of Independence that had its origin in the Liberating Expedition of Peru, under the command of José de San Martín in 1820.

Successively, new Peruvian regiments were created, organized until the end of the war, and which are the origin of the Peruvian Army. Units from the royalist side also switched sides, such as the Numancia Regiment. These troops were led by generals Rudecindo Alvarado and Andrés de Santa Cruz in the successive campaigns against the ports of southern Peru. Finally, in 1823, the newly arrived units of the army of Gran Colombia under the command of Simón Bolívar joined this United Liberating Army. This Peruvian-Colombian army was commanded by Antonio José de Sucre in the final Ayacucho campaign.
