Vicente San Bruno

San Bruno and the Talavera Regiment embarked on July 19, 1814, arriving at the naval base of Talcahuano, the nucleus of royalist activity, on August 13. Brigadier Osorio succeeded in organizing local elements into a mobile army of some 5,000 men, of which the troops of the Talavera Regiment were practically the only Spaniards. This circumstance led the Talavera Regiment to manifest a marked disdain for its opponents and the Criollo troops in general, typical of Peninsulares recently arrived in the Americas.

On October 1, the two sides fought in Rancagua, an attempt to prevent the expeditionaries from taking Santiago. The Talavera attacked the enemy fortifications without bothering to send in either scouts or guerrillas. The result was that bombarded by the volley of shots, they were forced to retreat with heavy losses. Nevertheless, by November Spanish control had been reestablished, and San Bruno was put in charge of carrying out the orders of imprisoning the civilians suspected of having helped or sympathised with the independentists. On February 6, 1815, he became infamous when he opened the doors of the public jail of Santiago, and when the prisoners came out, had them all killed under the pretext that they were trying to escape.

After Francisco Marcó del Pont became Royal Governor, San Bruno acquired almost unlimited authority. Two of the squadrons of the Talavera Regiment were sent back to Perú, but San Bruno stayed in Chile as commander of the remaining squadron. On January 17, 1816, he was named president of the Court of Vigilance and Public Security, which acted as secret political police. As such he instituted a reign of terror in order to quash any possible rebellion.
