War of the Pacific
The War of the Pacific (Spanish: Guerra del Pacífico), also known as the Nitrate War (Spanish: Guerra del salitre) and 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.
This article is about the 19th-century war between Bolivia, Chile and Peru. For the Pacific theater of World War II, see War in the Pacific.
The direct cause of the war was a nitrate taxation dispute between Bolivia and Chile, with Peru being drawn in due to its secret alliance with Bolivia. Some historians have pointed to deeper origins of the war, such as the interest of Chile and Peru in the nitrate business, a long-standing rivalry between Chile and Peru for regional hegemony, as well as the political and economical disparities between the stability of Chile and the volatility of Peru and Bolivia.[A]
On February 1878, Bolivia increased taxes on the Chilean mining company Compañía de Salitres y Ferrocarril de Antofagasta (CSFA), in violation of the Boundary Treaty of 1874 which established the border between both countries and prohibited tax increases for mining. Chile protested the violation of the treaty and requested international arbitration, but the Bolivian government, presided by Hilarión Daza, considered this an internal issue subject to the jurisdiction of the Bolivian courts. Chile insisted that the breach of the treaty would mean that the territorial borders denoted in it were no longer settled. Despite this, Hilarión Daza rescinded the license of the Chilean company, seized its assets and put it up for auction. On the day of the auction, February 14, 1879, Chile's armed forces occupied without resistance the Bolivian port city of Antofagasta, which was mostly inhabited by Chilean miners. War was declared between Bolivia and Chile on March 1, 1879, and between Chile and Peru on April 5, 1879.
Battles were fought on the Pacific Ocean, in the Atacama Desert, the Peruvian deserts, and the mountainous interior of Peru. For the first five months, the war played out in a naval campaign, as Chile struggled to establish a marine resupply corridor for its forces in the world's driest desert. Afterwards, Chile's land campaign overcame the Bolivian and Peruvian armies. Bolivia withdrew after the Battle of Tacna, on May 26, 1880, leaving allied Peru fighting alone for most of the war. Chilean forces occupied Peru's capital Lima in January 1881. Remnants and irregulars of the Peruvian army waged a guerrilla war but could not prevent war-weary Peruvian factions from reaching a peace deal with Chile involving territorial cessions.
Chile and Peru signed the Treaty of Ancón on October 20, 1883. Bolivia signed a truce with Chile in 1884. Chile acquired the Peruvian territory of Tarapacá, the disputed Bolivian department of Litoral (turning Bolivia into a landlocked country), and temporary control over the Peruvian provinces of Tacna and Arica. In 1904, Chile and Bolivia signed the Treaty of Peace and Friendship, which established definite boundaries. The 1929 Tacna–Arica compromise gave Arica to Chile and Tacna to Peru.
Peace[edit]
Peace treaty between Chile and Peru[edit]
On October 20, 1883, hostilities between Chile and Peru formally came to an end under the Treaty of Ancón, whose terms had Peru formally cede Tarapacá Province to Chile, and the use of the guano and nitrate resources to repay Peru's debts were regulated. Chile was also to occupy the provinces of Tacna and Arica for 10 years, when a plebiscite was to be held to determine nationality. For decades thereafter, the two countries failed to agree on the terms of the plebiscite. Finally, in 1929, mediation under US President Herbert Hoover caused the Treaty of Lima to be signed by which Chile kept Arica, and Peru reacquired Tacna.
Military analysis[edit]
Comparison[edit]
As the war began, the Peruvian Army numbered 5,241 men of all ranks, organized in seven infantry battalions, three squadrons of cavalry and two regiments of artillery.[166] The most common rifles in the army were the French Chassepot and the Minié rifles. The artillery, with a total of 28 pieces, was composed mostly of British-made Blakely cannons and counted four machine guns. Much of the artillery dated from 1866 and had been bought for the Chincha Islands War against Spain.[167] The mounts used by the cavalry were small and inferior to those used by the Chileans.[167]
The Bolivian Army numbered no more than 2,175 soldiers and was divided into three infantry regiments, two cavalry squadrons, and two sections of artillery.[94] The Colorados Battalion, President Daza's personal guard, was armed with Remington Rolling Block rifles, but the remainder carried odds and ends including flintlock muskets. The artillery had rifled three pounders and four machine guns, and the cavalry rode mules given a shortage of good horses.[167]
The regular Chilean Army was well equipped,[168][169][170][171] with 2,694 soldiers. The regular infantry was armed with the modern Belgian Comblain rifle, of which Chile had a stock of some 13,000. Chile also had Gras, Minié, Remington and Beaumont rifles, most of which fired the same caliber cartridge (11 mm). The artillery had 75 artillery pieces, most of which were of Krupp and Limache manufacture, and six machine guns. The cavalry used French sabers and Spencer and Winchester carbines.[172]
Strategy[edit]
Control of the sea was Chile's key to an inevitably difficult desert war: supply by sea, including water, food, ammunition, horses, fodder, and reinforcements, was quicker and easier than marching supplies through the desert or across the Bolivian high plateau. While the Chilean Navy started an economic and military blockade of the Allies' ports, Peru took the initiative and used its smaller navy as a raiding force. The raids delayed the ground invasion for six months and forced Chile to shift its fleet from blockading to hunting and capturing the Huáscar. After achieving naval supremacy, sea-mobile forces proved to be an advantage for desert warfare on the long coastline. Peruvian and Bolivian defenders found themselves hundreds of kilometers from home, but the Chilean forces were usually just a few kilometers from the sea.
The Chileans employed an early form of amphibious warfare, which saw the co-ordination of army, navy, and specialized units. The first amphibious assault of the war took place when 2,100 Chilean troops took Pisagua on November 2, 1879. Chilean Navy ships bombarded beach defenses for several hours at dawn, followed by open, oared boats landing army infantry and sapper units into waist-deep water under enemy fire. An outnumbered first landing wave fought at the beach; the second and third waves in the following hours were able to overcome resistance and move inland. By the end of the day, an expeditionary army of 10,000 had disembarked at the captured port. In 1881 Chilean ships transported approximately 30,000 men, along with their mounts and equipment, 500 miles (800 km) in order to attack Lima.[173] Chilean commanders were using purpose-built, flat-bottomed landing craft that would deliver troops in shallow water closer to the beach, possibly the first purpose-built amphibious landing craft in history:[174] "These 36 shallow draft, flat-bottomed boats would be able to land three thousand men and twelve guns in a single wave."
Chile's military strategy emphasized preemption, offensive action, and combined arms. It was the first to mobilize and deploy its forces and took the war immediately to Bolivian and Peruvian territories. It adopted combined arms strategy that used naval and ground forces to rout its allied foes and capture enemy territory.[10]: 163 It landed ground forces in enemy territory to raid in strength to split and to drive out defenders, and it then garrisoned the territory as the fighting moved north. Chileans received the support of Chinese immigrants who had been enslaved by Peruvians and joined the Chilean Army[175] during the campaign of Lima and in the raids to the north Peruvian cities.
Peru and Bolivia fought a defensive war, maneuvering through long overland distances and relied when possible on land or coastal fortifications with gun batteries and minefields. Coastal railways reached to central Peru, and telegraph lines provided a direct line to the government in Lima.
The occupation of Peru from 1881 and 1884 took a different form. The theater was the Peruvian Sierra, where the remains of the Peruvian Army had easy access to the population, resource, and supply centers far from the sea, which supported indefinite attrition warfare. The occupying Chilean force was split into small garrisons across the theater and could devote only part of its strength to hunting down dispersed pockets of resistance and the last Peruvian forces in the Sierra. After a costly occupation and prolonged counterinsurgency campaign, Chile sought a diplomatic exit. Rifts within Peruvian society and Peruvian defeat in the Battle of Huamachuco resulted in the peace treaty that ended the occupation.
Technology[edit]
Both sides used late 19th-century military technology, such as breech-loading rifles and cannons, remote-controlled land mines, armor-piercing shells, naval torpedoes, torpedo boats, and purpose-built landing craft. The second generation of ironclads, designed after the Battle of Hampton Roads, were used in battle for the first time. That was significant for a conflict in which no major power was involved and attracted British, French, and US observers. During the war, Peru developed the Toro Submarino ("Submarine Bull"), which never saw action and was scuttled at the end to prevent capture.
The USS Wachusett (1861) commanded by Alfred Thayer Mahan, was stationed at Callao, Peru, to protect American interests during the war's final stages. Mahan formulated his concept of sea power while he was reading history in a British gentlemen's club in Lima, Peru. The concept became the foundation for his celebrated The Influence of Sea Power upon History.[176][177]
