Battle of Pisagua

Battle context

The Battle of Pisagua was the opening amphibious operation of the Chilean land campaign in the War of the Pacific. By driving Bolivian-Peruvian defenders under Gen. Juan Buendia back from the shore, Chilean forces under Erasmo Escala, supported by the Chilean Fleet, secured a beachhead that allowed an initial force of approximately 1,000 soldiers to disembark in two assault waves onto Peruvian territory. The landing placed Chilean troops inside the Tarapacá Department, described as the principal territory in dispute in the war. Control of this port gave Chile a foothold from which to project force inland, making Pisagua a strategically consequential entry point into the contested nitrate-producing region that lay at the center of the broader conflict.
