The Battle of La Concepción (Spanish: Batalla de Concepción) was fought between Chilean and Peruvian forces on July 9 and 10, 1882, during the Breña campaign of the War of the Pacific. Heavily outnumbered, the Chilean detachment of 77 men under the command of Captain Ignacio Carrera Pinto was annihilated by a 1,300-strong Peruvian force, many of them armed with spears, commanded by Col. Juan Gasto and Ambrosio Salazar after a 27-hour fight in the small town of Concepción in the Peruvian Andes.
