Lead
The Naval campaign of the War of the Pacific or Saltpeter war, was a naval campaign that took place from 1879 to 1884, involving Peru (as well as Bolivia), and Chile, undertaken in order to support land forces in the Atacama Desert. Although the conflict lasted until 1884, the primary naval engagements occurred between 1879 and 1880. Due to the rough terrain and few transport methods it was imperative to have control of the ports in order to have a good supply source in the region. It resulted in a successful campaign by Chile, and the success of their land campaigns eventually led to a Chilean victory, which cut off Bolivia's access to the coast.

Navies and ships involved
(needs editing) In 1879 Bolivia did not possess any ships, but on March 26, 1879, Bolivian President Hilarion Daza Groselle formally offered letters of marque to any ships willing to go to combat for Bolivia. Bolivia had not signed the Paris Declaration Respecting Maritime Law but the United States, Britain and France stood by the treaty and refused to accept the legality of Bolivia's act. Since Bolivia did not have any ports because Chile had occupied them, and because Peru discouraged the use of Letters of Marque, the naval conflict was left to be resolved between Chile and Peru.

The power of the Chilean navy was based on the twin central-battery ironclad frigates, Cochrane and Blanco Encalada. The rest of the fleet was formed by the corvettes O'Higgins, Chacabuco, Abtao, and Esmeralda, the gunboat Magallanes, and the schooner Covadonga.

The Peruvian navy based its power on the broadside ironclad frigate Independencia and the monitor Huáscar. The rest of the fleet was completed by the corvette Unión, the gunboat Pilcomayo, and the coastal monitors Atahualpa and Manco Cápac, purchased from the United States at the end of the Civil War The coastal monitors cannot be classed among the seagoing ships of Perú as they were permanently stationed, one at Callao and the other at Arica. Although both the Chilean and Peruvian ironclads seemed evenly matched, the Chilean ironclads had twice the armor and held a greater range and hitting power.

Battle of Angamos and the Capture of the Huáscar
Due to their successes, the Huáscar, and her captain Miguel Grau Seminario, became the primary target for the Chilean navy. In September of 1879, the decision was made to launch a land invasion of Peru with the intention of sectioning off Callao and Arica. The navy was split into two parts, under the control of Admiral Galvarino Riveros Cárdenas, and planned to blockade Callao and Arica. In order to be successful, Grau and the Huáscar needed to be eliminated. The battle took place on October 9, 1879, it involved the Chilean ironclads Cochrane and the Blanco Encalada, and the Peruvian ironclad Huáscar and wooden Unión. Admiral Grau believed he could evade the Cochrane due to his perceived speed advantage, but he was unaware of the upgrades to the ironclad that elevated its speed to 12 knots, which equaled the Huáscar. After falling into the Chilean trap, the Huáscar had no choice but to engage the Cochrane. At 9:25 AM, the Huáscar fired on the Cochrane, which prompted the ironclad to move close to the Huáscar. After getting closer to the Huáscar, the Cochrane open fired, striking the Huáscar multiple times. At 9:45 AM, one of the shots hit the conning tower of the Huáscar, which was occupied by Admiral Grau, killing him instantly. By 10:10 AM, the Blanco Encalada arrived, and by 10:55 AM, the battle was essentially over. After failing to intentionally sink the ship, the remaining crew of the Huáscar were captured and the ship was added to the Chilean fleet. By eliminating the most formidable Peruvian ship and Admiral Grau, the Chilean gained control of the sea, which they would retain for the remainder of the conflict. This was the last engagement at sea between the two navies. The Chilean navy began to focus on blockades, used their weaponry to support land troops, and bombarded cities.

Blockade of Arica[edit]
The blockade of Arica was conducted by the Chilean navy's ships Cochrane, Covadonga, and an unnamed armed transport, all three having arrived by the 7th of December, 1879. The town of Arica was relatively well defended, with four batteries including one on a bluff, the other three built of sand and turf. Several foreign ships observed during the blockade, including corvettes from the US, France, and the UK. They also observed, on the 13th, an allied army of mixed armament, about 2,000 strong, augmenting the garrison to around 8,000. Many were native Amerindians from the mountains.

Arica was later taken by Chile in the Battle of Arica, on June 7,1800, after the town had been weakened by the blockade, which prevented supply from the sea.

Blockade of Callao[edit]
Main article: Bombardment of Callao

Callao was the primary port in Peru, located only eight miles (13 kilometers) from the capital city, Lima. The blockade began on April 10, 1880 and would last until January 17, 1881. Lima was captured by Chilean land forces on December 17,1880, and when the Peruvian navy got word of this, they preceded to scuttle all the ships that still resided in Callao's port. The city would be taken a month after Lima on January 17, 1881, which led to the eventual Chilean victory.
