War of the Pacific: The Battle of Arica, the assault and capture of Morro de Arica (Arica Cape), ends the Campaña del Desierto (Desert Campaign).

The War of the Pacific, also known by multiple other names, was a war between Chile and a Bolivian–Peruvian alliance from 1879 to 1884. Fought over Chilean claims on coastal Bolivian territory in the Atacama Desert, the war ended with victory for Chile, which gained a significant amount of resource-rich territory from Peru and Bolivia.

The Battle of Arica, also known as Assault and Capture of Cape Arica, was a battle in the War of the Pacific. It was fought on 7 June 1880, between the forces of Chile and Peru.

Morro de Arica is a steep hill located in the Chilean city of Arica. Its height is 139 metres above sea level. It was the last bulwark of defense for the Peruvian troops who garrisoned the city during the War of the Pacific (1879–1883). Morro de Arica was assaulted and captured on June 7, 1880, by Chilean troops in the last part of the Tacna and Arica campaign. Morro de Arica rises steeply from the city and the sea, with a more gentle slope towards the east. A giant flag of Chile is flown on its summit. Morro de Arica was declared a national monument on October 6, 1971.
