Battle of Angamos

Battle context

The Battle of Angamos concluded a five-month Chilean naval campaign whose singular objective was the destruction of Peruvian naval power. The capture of the ironclad monitor Huáscar, commanded by Rear Admiral Miguel Grau Seminario, removed the most capable Peruvian warship from the conflict and ended Peru's ability to contest control of the Pacific. With Chilean naval supremacy established, Chile gained freedom to move troops and supplies along the coast at will, a prerequisite for the land campaigns that would follow deeper into Peruvian and Bolivian territory. Angamos thus marked the transition of the War of the Pacific from a contest for sea control to a largely one-sided ground offensive.
