Original:  In 1879, Chile began to exact a tax of 40 cents per "quintal métrico" (100 kg), increasing to $1.60 in 1880.Thomas F. O'Brien, "The Antofagasta Company: A Case Study of Peripheral Capitalism", Duke University Press, Hispanic American Historical Review, 1980, pp. 21–23 As provided by the secret treaty, the allies agreed in the Protocol of Subsidies for Bolivia to bear the costs of the war. The agreement, which regulated the tax income for many years, caused resentments and fears in Bolivia, whose deployment of forces to Tacna was seen as helping Peru. Also, Bolivia knew that its army would be sent not to free the occupied region of Bolivia but to protect Peru. As Daza and his officers came to Tacna and Arica, they failed to see the expected Peruvian military strength and understood that their position of power in Bolivia was threatened by a defeat of the Allies. The Bolivian historian Querejazu suggests that Daza successfully used the Chilean offer of Tacna and Arica for Bolivia to exert pressure on Peru to get a more favorable Protocol of Subsidies. The reason that Daza abandoned the Peruvian forces in Iquique and turned back to Arica just before the Battle of San Francisco is uncertain. Some historians say that he wanted to keep the "Regimiento Colorados" untouched since the force secured his political power in Bolivia. Daza later stated that his officers refused to continue the march through the desert, but his shameful withdrawal accelerated his downfall, and he was succeeded by Narciso Campero. In the new government, there was a strong tendency to accept the Chilean offer of Tacna and Arica, but it was eventually refused. Bolivia signed the creation of the United States of Peru and Bolivia, a political fantasy without any practical consequences. Bolivia helped Peru with money and weapons, but the Bolivian army never again intervened in the war. In Peru, the political situation was complicated. President Prado had declared war on Chile for longstanding economical and political reasons but without the funds or international credit to finance the war. He turned over the administration of the state to Vice President Luis La Puerta de Mendoza to assume for himself the command of the army. Because of the Chilean blockade, Peru could not export revenuemaking goods via its ports. As a consequence, public revenue was half of what had been expected, and spending tripled. The Peruvian government in 1879 experienced several political crisis and seven ministers of finance. General Buendía, who led the defeated allied troops in Iquique, and More, chief of the sunken warship Independence, were both put on trial but were eventually acquitted. The Peruvian government was confronted with widespread rioting in Lima because of its failures. On December 18, 1879, as the fall of Iquique became known in Peru, Prado went from Callao to Panama, allegedly with the duty to oversee the purchase of new arms and warships for the nation. In a statement for the Peruvian newspaper El Comercio, he turned over the command of the country to Vice President Luis La Puerta de Mendoza. History has condemned his departure as a desertion. Cap. IV "La crisis hacendaria y política" Nicolás de Piérola overthrew Puerta's government and took power on December 23, 1879. Piérola has been criticised because of his sectarianism, frivolous investment, bombastic decrees, and lack of control in the budget, but it must be said that he put forth an enormous effort to obtain new funds and to mobilize the country for the war. Basadre considered his work an act of heroism, abnegation in a country invaded, politically divided, militarily battered, and economically bloodless.

In 2008, 280 women were receiving a pension as the daughter or wife of a veteran. Landing and deployment of Chilean and Allied troops during the Campaign of Tacna and Arica from January to June 1880. Meanwhile, Chile continued its advances in the Tacna and Arica Campaign. On November 28, ten days after the Battle of San Francisco, Chile declared the formal blockade of Arica. On December 31, a Chilean force of 600 men carried out an amphibious raid at Ilo as a reconnaissance in force, to the north of Tacna and withdrew the same day. On February 24, 1880, approximately 11,000 men in 19 ships, protected by Blanco Encalada, Toro, and Magallanes and two torpedo boats, sailed from Pisagua. Two days later, on February 26, the Chileans arrived off Punta Coles, near Pacocha, Ilo. The landing took several days to conclude but faced no resistance. The Peruvian commander, Lizardo Montero, refused to try to drive the Chileans from the beachhead, as the Chileans had expected. On March 22, 3,642 Chilean troops defeated 1,300 Peruvian troops in the Battle of Los Ángeles, cutting any direct Peruvian supply from Lima to Arica or Tacna (supply was possible only through the long way, via Bolivia). "Baquedano could not simply bypass the Peruvian troops, whose presence threatened Moquegua as well as the communications network extending southeast across the Locumba Valley to Tacna and northwest to Arequipa and northeast to Bolivia" After the Battle of Los Ángeles, only three allied positions remained in southern Peru: General Leyva's 2nd Army at Arequipa (including some survivors from Los Ángeles), Bolognesi's 7th and 8th Divisions at Arica, and at Tacna the 1st Army. These forces were under Campero's direct command. specifies 3,100 men in Arequipa, 2,000 men in Arica and 9,000 men in Tacna, but this figure contradicts the total numbers given (below) by William F. Sater in page 229. However, the numbers proved meaningless, as the Peruvians were unable to concentrate troops or even to move from their garrisons. "...it became evident that there was a total lack of the necessary transport for even the minimum amount of supplies and water" "The allied force, he [Campero] concluded lacked sufficient transport to move into the field its artillery as well as its rations and, more significantly, its supplies of water." After crossing of desert, on May 26 the Chilean army (14,147 men) destroyed the allied army of 5,150 Bolivians and 8,500 Peruvians in the Battle of Tacna. The need for a port near the army to supply and reinforce the troops and to evacuate the wounded compelled the Chilean command to concentrate on the remaining Peruvian stronghold of Arica. On June 7, after the Battle of Arica, the last Peruvian bastion in the Tacna Department fell. After the campaign of Tacna and Arica, the Peruvian and Bolivian regular armies largely ceased to exist, and Bolivia effectively left the war. Lynch's Expedition Lynch's Expedition to Chimbote, Supe, Paita, Eten and islas de Lobos, from September to October 1880. To show Peru the futility of further resistance, on September 4, 1880 the Chilean government dispatched an expedition of 2,200 men "Lynch's force consisted of the 1° Line Regiment and the Regiments "Talca" and "Colchagua", a battery of mountain howitzers, and a small cavalry squadron for a total of twenty-two hundred man" to northern Peru under the command of Captain Patricio Lynch to collect war taxes from wealthy landowners. "[The Chilean government thought that it was possible to demonstrate to the enemy the futility of any defense of Peruvian territory not only against the whole [Chilean] army but also against small [Chilean] divisions. That was the purpose of the expedition, which the claims, insults, and affliction in the official documents of Peru and in the press had made famous" (Original: "[El gobierno chileno] Creía entonces que todavía era posible demostrar prácticamente al enemigo la imposibilidad en que se hallaba para defender el territorio peruano no ya contra un ejército numeroso sino contra pequeñas divisiones. Este fué el objeto de una espedicion que las quejas, los insultos i las lamentaciones de los documentos oficiales del Perú, i de los escritos de su prensa, han hecho famosa.") On September 10, Lynch's Expedition reached Chimbote, more than 300 km (186 mi) north of Lima. The expedition levied taxes of $100, 000 in Chimbote, $10,000 in Paita, $20, 000 in Chiclayo, as well as $ 4, 000 in Lambayeque in local currencies;
