Further, the Chilian envoy Irizarri, passing through Buenos Ayres on his way to England, there signed a treaty of alliance with the Argentine Government:—“To put an end to Spanish domination in Peru by means of a combined expedition.”
In June, 1818, Bolívar stretched out the right hand of fellowship to the Argentine people by an official letter to the Government, and by a proclamation to “the inhabitants of the River Plate,” in which he sets forth his favourite policy of a union of all the peoples of South America. Some months later on O’Higgins wrote to Bolívar, proposing to him an alliance based upon the continental ideas of San Martin.
San Martin had written from Mendoza to the Government of Chile and to Balcarce, informing them of his plans for the expedition to Peru, giving three months for collecting the necessary supplies. When he reached Santiago nothing had been done, and the revenues were mortgaged for months to come. He then wrote to the Argentine Government, giving a most miserable account of the financial state of Chile, and the consequent inefficiency of the Army of the Andes, which he suggested should be withdrawn from Chile as the projected expedition was for the time impossible. He also wrote to the Government of Chile, expressing his fears of the speedy dissolution of the united army, and proposed that a part of it should be employed in desultory attacks on the coasts of Peru, while he himself resigned the command.
On receiving no satisfactory reply, he concentrated the Army of the Andes at the upper part of the valley of Aconcagua, crossed over himself with a small detachment to Mendoza, and was soon after followed by a division of 1,200 men, by which operation he brought pressure to bear on the Chilian Government by leaving them to their own resources, while he recruited his cavalry in their own country, and preserved Cuyo from being drawn into the vortex of anarchy which at that time desolated the United Provinces. In this internecine strife he took no part whatever, but the presence of a portion of his army in Mendoza strengthened the hands of Government and aided greatly in bringing about a truce.
The first news which San Martin heard on his arrival in Mendoza was an account of a terrible tragedy which had just occurred in San Luis. This city was the prison of the principal captives of Maipó and Chacabuco. They were well treated by Dupuy, the Deputy-Governor, who had only a picket of militia under his orders, and who trusted more to the wide Pampa which surrounded them than to prison walls for their security. The officers were not confined in the public prison, but lived in houses and mixed freely with the people. They were so many that they thought they would have no difficulty in overpowering the small garrison. A plan of escape had been for months discussed among them, when, on the 1st February, 1819, Dupuy, on account of the disturbed state of the country round, issued an order that they were not to leave their houses after sundown. Captain Carretero of the Burgos regiment was the head of the conspirators. On the evening of the 7th he invited a number of his comrades to breakfast with him the next morning, proposing to spend the day killing vermin in his orchard. At six o’clock next morning twenty officers met at his house; he led them into the orchard and gave them a light breakfast of bread and cheese washed down with brandy; then, drawing a poniard, he told them that in an hour they would all be free or dead, and distributed ten knives among them, telling the rest to arm themselves with sticks. Captain La Madrid was sent with ten men to seize the barracks, Captain Salvador, with six, to capture the prison and set the prisoners at liberty; while he went off to join Ordoñez, Primo de Rivera, and Morla, who, with their orderlies, would make sure of the Deputy-Governor.
The first party reached the barracks, disarmed the sentry, and overpowered the guard. In an inner yard were a number of Gaucho rebels under arrest, among them being one who afterwards acquired terrible notoriety as a Gaucho chieftain—Juan Facundo Quiroga. Quiroga led his fellow-prisoners to the assistance of the soldiers, and, armed only with the broken shaft of a lance, fought so fiercely that all the assailants except one were killed, and he was badly wounded.
The party sent against the prison on crossing the great square were met by the officer in command of the militia, who was galloping about with his sabre drawn, calling the people to arms. Armed men poured out of the houses upon them; only one escaped, the rest being killed.
Meantime Carretero, Morgado, and Morla had gone to Dupuy’s house and asked to see him. Being admitted, they set upon him, and after a short struggle threw him down, when Ordoñez and Primo de Rivera entered with their orderlies, bringing the sentry with them, after shutting the outer door. But a militia captain and a doctor who were with Dupuy, had escaped and gave the alarm. A number of the townspeople, headed by a young officer named Pringles, surrounded the house with shouts of “Death to the Goths.” Dupuy rushed to the door and opened it, the crowd poured in. Ordoñez, Morla, Carretero, and Morgado were killed. Primo de Rivera, finding a loaded carbine in an ante-room, shot himself through the head.
Of forty conspirators twenty-four were killed, the rest were tried by a court-martial, of which Dr. Monteagudo was President. Eight were acquitted, seven were shot, but young Ordoñez, a nephew of the General, was spared, partly on account of his youth, and partly because he was engaged to a young lady of the city, whose relatives interfered on his behalf. He was afterwards set at liberty by San Martin, who also gave Quiroga his freedom as a reward for his bravery, a favour which Quiroga never forgot.
Marcó del Pont, ex-Governor of Chile, was also at that time a prisoner in San Luis, but took no part in the conspiracy and was not molested.
