Timeline of The Chilean War of Independence - Reconquista

Reconquista

The viceroy Abascal confirmed Mariano Osorio as governor of Chile, although a later disagreement between the two would result in Osorio's removal and the installation of Francisco Marcó del Pont as governor in 1815. In any case, the Spanish believed that it was necessary to teach the revolutionaries a good lesson and embarked on a campaign of fierce political persecution, led by the infamous Vicente San Bruno. The patriots found in Santiago—among whom were members of the First Junta—were exiled to the Juan Fernández Islands. Far from pacifying the patriots, these actions served to incite them, and soon even the most moderate concluded that anything short of independence was intolerable.

A large group of patriots (among them Carrera and O'Higgins) decided to flee to Mendoza, an Andean province of the newly independent Argentina. At the time, the governor of this province was José de San Martín, a leader of the Argentine independence movement who would become regarded as the "Simón Bolívar" of the southern part of Spanish South America. Upon the arrival of the exiles, San Martín immediately began to favor O'Higgins (probably because of their shared membership in the Logia Lautaro, a pro-independence secret society).Carrera's influence begun to fade and ended finally when he was executed by firing squad in 1821.

While San Martín and O'Higgins organized an army to recross the Andes and recapture Santiago, they charged the lawyer Manuel Rodríguez with the task of mounting a guerrilla campaign. The goals of the campaign were to keep the Spanish forces off balance, ridicule San Bruno, and generally bolster the morale of the patriots. Through his subsequent daring exploits, Rodríguez became a romantic hero of the revolution. In one of his more celebrated actions, he disguised himself as a beggar and succeeded in obtaining alms from Governor Marcó del Pont himself, who by that time had put a price on Rodríguez's head.

The liberating Army of the Andes was prepared by 1817. After a difficult crossing the Andes, royalist forces led by Rafael Maroto were encountered on the plain of Chacabuco, to the north of Santiago. The resulting Battle of Chacabuco, on February 12, 1817, was a decisive victory for the independence forces. As a result, the patriots re-entered Santiago. San Martín was proclaimed Supreme Director, but he declined the offer and put O'Higgins in the post, where he would remain until 1823. On the first anniversary of the Battle of Chacabuco, O'Higgins formally declared independence.
