The Battle of Punta Gruesa took place on May 21, 1879 during the War of the Pacific between Chile and Peru. This may be labelled as the second part of the Naval Battle of Iquique, although it is described in many sources as a separate battle. During the first year of the war, Chilean war efforts were focused on destroying the Peruvian Navy, since the strategic importance of sea domination. This was in order to enable the Chilean Navy to help the army to conquer Bolivian and Peruvian territories with troop landings and port blockades without interference.
