The Tacna and Arica campaign is known as the stage of the War of the Pacific after the Chilean conquest of the Peruvian department of Tarapacá, ending with Chilean domination of the Moquegua department in southern Peru. During this campaign Bolivia retired from the war after the Battle of Tacna, and Peru lost the port of Arica. Also, Manuel Baquedano assumed command as the new Commander in Chief of the Chilean Army, and the Allied Presidents were thrown out of office and replaced by Nicolas de Pierola in Peru and General Narciso Campero in Bolivia.
