War of the Pacific: The Battle of Topáter, the first battle of the war, is fought between Chile and the joint forces of Bolivia and Peru.

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 war demonstrated Chile's military-technological superiority over its opponents at the time.
