The Granaderos unit was instrumental in the Revolution of October 8, 1812 which deposed the government and installed a new Triumvirate, considered to be more committed to the cause of Independence. In fact, this second Triumvirate convened a national assembly which was meant to declare Independence. The Assembly, however, first decided replace the Triumvirate with a new unipersonal Executive office, the Supreme Director of the United Provinces of the Río de la Plata, and elected Gervasio Antonio de Posadas for that role.
