Although reluctant, Sucre agreed with O'Connor and ordered the army to set up a defensive position where the Irishman had suggested. The Spanish army attacked and were defeated by the patriots. This battle is considered the end of the Spanish-American Wars of independence. Spanish General Canterac confessed to O'Connor after the battle that the choice of position made by the patriot army was a major factor in the defeat of the royalists.


Upper Peruvian Campaign

In 1825
Antonio José de Sucre Antonio José de Sucre y Alcalá (; 3 February 1795 – 4 June 1830), known as the "Gran Mariscal de Ayacucho" (), was a Venezuelan general and politician who served as the president of Bolivia from 1825 to 1828. A close friend and associate ...

The nascent years of the Bolivian Republic (1825-1829)

In 1826, Francisco O'Connor was appointed military governor of

, as he was in Sucre the night of the President's untimely assassination. Not completely certain of what had occurred that night, O'Connor finally uncovered the truth years later from one of Blanco's guards the night of his death, writing it years later in his ''Recuerdos''. The Irishman writes the following account of the murder:
There were rumors, of course, that General Blanco had been assassinated by the orders of the captain of the National Guard and that the first Chief of First Battalion, Colonel José Ballivian. In fact, many suppose it that way until now in Chuquisaca; however, finding myself in Peru in the year 1836 with the Bolivian Army... Lieutenant Colonel Prudencio Deheza, the same one who commanded the guard corps in the Recoleta convent of Chuquisaca the night of the cruel assassination of General Blanco, told me about that tragic event as follows: The order that was posted to the guards that day was: that in case of any attempt by the ''cholada'' he indigenous popular masses of Boliviato rescue the prisoner, that he not be allowed to escape with his life. This order was read to all the troops that made up the guard; and that same night, at midnight, the sentinel stationed in the corridor, sounded the alarm, and stated that groups of ''cholos'' were approaching the high wall in front of the convent. All guards armed themselves, and Deheza set up in his designated position. All this happened next to the cell in which the unfortunate General Blanco was imprisoned. With a sentinel at the door and another inside the same cell. At this time, Blanco was sleeping on a pallet in his cell, and hearing the noise in the corridor he was awaken. He was going to the door to see what was happening, when the sentinel in sight pushed him with his bayonet onto the pallet and shot him. The captain of the guard entered the cell and the sentinel told him that the prisoner had tried to escape; the gatekeeper also entered the cell, and shot Blanco a second time. Deheza then entered and finished him off with his sword.


The Presidency of Santa Cruz

O'Connor had retired to his hacienda in Tarija after the tragic end of President Blanco, where he planned to remain unless called upon by his country. The possibility of a Peruvian invasion and the souring of relations between Peru and Bolivia compelled President
Andrés de Santa Cruz Andrés de Santa Cruz y Calahumana (; 30 November 1792 – 25 September 1865) was a Bolivian general and politician who served as interim president of Peru in 1827, the interim president of Peru from 1836 to 1838 and the sixth president of ...

, a region long considered to be Argentine by the citizens of that country. Santa Cruz, in a letter to O'Connor, stated:
No one knows that territory he borderlands of the Tarija Departmentbetter than you, which could soon become the theater of a campaign. You will take an Infantry battalion and a Regiment of Cavalry, will march to Tarija, and will put the whole province in a state of defense against that gaucho uiroga
Quiroga's invasion never came, and Santa Cruz attempted to incorporate an uninterested O'Connor into his administration. He served on an interim basis as Minister of War yet again in the year 1833, and was made President of the Council of War, for which he participated in the infamous trial of Colonel Manrique. Santa Cruz had wanted a death sentence for the colonel, however, when O'Connor ruled to fire Manrique from the army instead, a clash between the President and the Irishman took place. O'Connor, insulted by said clash, decided to retire to the borderlands in Tarija, declaring he would never serve in his administration again.


The Peru–Bolivian Confederation


The formation of the Confederation

However, in 1835, Santa Cruz wrote a letter, calling him to arms. In 1833, General
Agustín Gamarra Agustín Gamarra Messia (27 August 1785 – 18 November 1841) was a Peruvian soldier and politician, who served as the 4th and 6th President of Peru. Gamarra was a Mestizo, being of mixed Spanish and Quechua descent. He had a military life s ...

. It was at this point that Santa Cruz entered into an alliance with Orbegoso, with the promise of a Confederation between Peru and Bolivia. In 1836, O'Connor marched alongside Santa Cruz and the Bolivian Army to the city of
Arequipa Arequipa (; Aymara language, Aymara and ), also known by its nicknames of ''Ciudad Blanca'' (Spanish for "White City") and ''León del Sur'' (Spanish for "South's Lion"), is a city in Peru and the capital of the eponymous Arequipa (province), ...
, where Salaverry and his army were located. When the Bolivian Army entered the city, Salaverry's army was leaving, heading toward Uchumayo. Santa Cruz decided to remain in the city instead of pursuing the enemy, and, on the other side of the river, Salaverry's army rained heavy fire onto the city for six days. On 4 February, General Ballivián led a charge which was completely defeated by Salaverry, with O'Connor's division having to cover for the defeated and retreating first division. On the morning of 7 February, O'Connor spotted Salaverry's army marching toward Huascacachi. Salaverry's intention was to cut off the Bolivian supply, preventing any possible retreat by Santa Cruz into Bolivia. Sensing an opportunity, since the enemy forces were marching in thin files and were not in a position to fight, O'Connor informed Santa Cruz who ordered an immediate attack. A charge led by General

effectively decided the outcome of the so-called Battle of Socabaya, ending in the capture and later execution of Salaverry and several of his officers.


The war against Chile

With the new Confederation secured, Santa Cruz made three major mistakes: the annulment of the treaty of peace and friendship with Chile; the promotion of the civilian Mariano Enrique Calvo to

in 1839. O'Connor describes these as "the major blunders which cost Santa Cruz", the first being the anger of the army at the promotion of Calvo:
Congress passed a law... which had Doctor Mariano Enrique Calvo, Prosecutor of the Supreme Court and then appointed Vice President of Bolivia, in charge of the Executive Power in the absence of General Santa Cruz, promoted to division general. The soldiers of the army were very offended by the appointment of Calvo, and they told me that they did not want to accept a ''peso'' of the money that had been granted to them by Congress, and that they did not approve and could not approve the appointment of a civilian to the rank of division general.
The second major blunder which O'Connor describes is the annulment of the treaty with Chile signed under Salaverry, which had led to the declaration of war by said nation:
s for the war with Chile the cause was the decree passed by General Santa Cruz which annulled the treaty of peace, friendship, and trade concluded between Salaverry, the intrusive president of Peru, and the Government of Chile... and the Captain General anta Cruzknew it and must have weighed on him; however, he was so proud as a result of the victory at Socabaya that he imagined himself in a position to do whatever occurred to him at will, without looking at one side or the other, and this fact, which seemed insignificant to him, was the cause of his downfall and that of all the Confederation.
The third major blunder O'Connor mentions is the disrespect toward and marginalization of General Velasco, whose defection in 1839 would be the event which finally toppled Santa Cruz in Bolivia:
I received from Lima the plaque of a Great Dignitary of the Legion of Honor of Bolivia, which was worth the pension of five hundred ''pesos'' for life. This dignity was not conferred on General Velasco, who had been Vice President of Bolivia for many years, and President also after the death of General Pedro Blanco, on the last night of 1828, and Chief of Staff of the Bolivian Army during the Battle of Yanacocha. Another reckless decision by General Santa Cruz, as this was the real cause behind the defection of General Velasco in Tupiza, and his pronouncement for the Restoration in February 1839, when he learned of the defeat of the Confederation Army in Yungay.
The war with Chile continued when
Diego Portales Diego José Pedro Víctor Portales y Palazuelos (; June 16, 1793 – June 6, 1837) was a Chilean statesman and entrepreneur. As a minister of president José Joaquín Prieto's government, he played a pivotal role in shaping the state and po ...
was assassinated by his own men, followed by a mutiny in Oruro against Santa Cruz. Sensing an opportunity, the Chileans invaded Peru and were able to occupy the city of Arequipa. The Army of the Confederation far outnumbered that of the Chilean Army in Arequipa. However, instead of achieving a decisive and crushing victory over Chile, Santa Cruz opted for the signing of a peace treaty, known as the Treaty of Paucarpata, celebrated on 17 November 1837. O'Connor vehemently disagreed with such a treaty, telling Santa Cruz that he did not believe the Chilean government would abide by such a treaty. After the treaty was signed, Santa Cruz negotiated with General

had, like the Chileans, also declared war on Santa Cruz. O’Connor was sent hurriedly to Tarija alongside General Braun to prevent the Argentine army under Gregorio Paz from seizing the province. The Argentines intended to claim the province of Tarija, long disputed with Bolivia. Although the Bolivian high command believed the enemy was located in San Luis, the Argentines were actually advancing toward Tarija. O’Connor and Braun pursued Paz and eventually caught up to his army near the Montenegro mountain range, on the banks of the

on 24 June 1838. The Bolivians led an uphill charge against the Argentines, who were holding a defensive position. Although Paz's men were firing ferociously, the Bolivians under O’Connor led an impressive charge which resulted in the Argentine army abandoning their positions and fleeing to safety. Braun eventually caught up with O’Connor to discover the Argentine troops fleeing and abandoning all their belongings in the process. Thus, the Battle of Montenegro came to an end with a decisive Bolivian victory. Previously, on 11 June, the second division of the Argentine army, led by

The second Chilean campaign and the revolution of General Velasco

The Chileans were quick to resume hostilities with Santa Cruz, as the so-called treaty of Paucarpata was not ratified by the Chilean government. Landing in Peru, the Restoration Army, composed of Peruvian exiles and Chileans, was able to crush Santa Cruz in the decisive
Battle of Yungay The Battle of Yungay (or Yungai) was the final battle of the War of the Confederation, fought on January 20, 1839, near Santo Domingo de Yungay, Yungay, Peru. The United Restoration Army, led by Chilean General Manuel Bulnes, consisting mainly ...
, leading to the unravelling of the Confederation. On 9 February 1839, General Velasco proclaimed himself against Santa Cruz, and in the following days the Departments of Chuquisaca, La Paz, and Cochabamba declared themselves in favour of the rebellion. Velasco would erase O'Connor from the military list of Bolivia, resulting in the banishment of the latter from political and military affairs. O'Connor retired to his estate in Tarija, never to offer his services again for any government, especially not Velasco's.


Death and legacy

He died in Tarija on 5 October 1871 at eighty years of age. His memoirs entitled ''Independencia Americana: Recuerdos de Francisco Burdett O'Connor'' were published in 1895. O'Connor played a key role during the battles of Junin and Ayacucho, loyally serving Sucre and organizing with Santa Cruz what came to be among the fiercest and most well-trained armies in all of South America. This army united Peru and Bolivia and, although ephemeral, would score major victories against the armies of Chile and Argentina. He is among the few military officers during the Spanish American Wars of Independence to have received the title of Liberator.
