On the political front, the last remnants of optimism among patriots faded away with accusations of treason against Peruvian presidents José de la Riva Agüero and José Bernardo de Tagle. Riva Agüero deported deputies of the Peruvian Congress and organized another congress in Trujillo. After being found guilty of high treason by the Peruvian Congress he was banished to Chile. This act, in turn, was considered by Simón Bolívar to be treasonous. Tagle, who had earlier ordered all armies under his command to support Bolívar against the royalist enemy, was now pursued by Bolívar, who was looking to capture and execute him. Tagle took shelter with the royalists in the fortress of Callao, which was under siege.
