Callao, Battle of, Callao, Callao, Peru, 1866

The Battle of Callao (Spanish: Combate del Dos de Mayo, as it is known in South America) occurred on May 2, 1866, between a Spanish fleet under the command of Admiral Casto Méndez Núñez and the fortified battery emplacements of the Peruvian port city of Callao during the Chincha Islands War. The Spanish fleet bombarded the port of Callao (or El Callao), and eventually withdrew without any notable damage to the city structures, according to the Peruvian and American sources; or after having silenced almost all the guns of the coastal defenses, according to the Spanish accounts and French observers. This proved to be the final battle of the war between Spanish and Peruvian forces.
