On 3 July 1836 sailed bound to
Chiloé the brigantine
Orbegoso under the command of Freire, and on 7 July
Monteagudo under the command of Puga. During the voyage,
Monteagudo crew rose against Freire's partizans on board and proceeded to
Valparaíso to deliver the ship and the prisoners to the Chilean authorities. Freire on
Orbegoso, ignorant of what had happened, continued the route to Chiloé where the authorities surrendered to Freire without resistance. The Chilean government had been informed about the plot, and
Diego Portales, defense minister of the government ordered
Monteagudo manned with loyal crew and troops to Chiloé. As she arrived, Freire, assuming the ship was still under the command of Puga, ordered Puga to land with his men. This was executed and thus admitted into the fort. The troops of the fort, informed of the situation returned to the Chilean authorities and Freire was arrested. Simultaneously to the capture of Freire in Chiloé, Portales ordered and to capture the naval ships of the Peru-Bolivian Confederation anchored in Callao, without a declaration of war. They captured on 21 August 1836 the ships
Santa Cruz, the brig
Arequipeño and the schooner
Peruviana. ==The War of the Confederation==
