Throughout the War of the Pacific, General Andrés Avelino Cáceres had organized the Ejército de la Breña to conduct guerrilla resistance against Chilean forces in the Peruvian Andes. Despite Chile's dominance in coastal regions, Cáceres continued to mount a stubborn campaign in the highlands, prompting Chile to commit forces to eliminate this remaining organized resistance.
On 10 July 1883, Chilean forces under Colonel Alejandro Gorostiaga engaged and decisively defeated the Peruvian army commanded by General Cáceres near the town of Huamachuco. The battle resulted in the destruction of the Ejército de la Breña and the death of prominent Peruvian officer Colonel Leoncio Prado, effectively ending organized military opposition in the Andes.
The Chilean victory at Huamachuco eliminated the last significant Peruvian resistance force, removing any remaining military leverage Peru held in the war. This paved the way for the Treaty of Ancón, which formally ended the War of the Pacific and imposed significant territorial concessions on Peru.
