Elío created the Junta of Montevideo, which would scrutinise all the orders from Buenos Aires and reserve the right to ignore them, but did not openly deny the authority of the Viceroy or declare Montevideo independent. Martín de Álzaga began a mutiny to remove Liniers. On January 1, 1809, an open cabildo (an extraordinary meeting of vecinos, prominent people of the city) chaired by Álzaga demanded the resignation of Liniers and the appointment of a local junta. The Spanish militia and a group of people summoned by the meeting gathered to support the rebellion. A small number of criollos, notably Mariano Moreno, supported the mutiny, but most of them did not. They felt that Álzaga wanted to remove the Viceroy to avoid his political authority while keeping the social differences between criollos and peninsulars unchanged. The riot was quickly routed when criollo militias led by Cornelio Saavedra surrounded the plaza and dispersed the rebels. As a result of the failed mutiny, the rebel militias were disarmed. This included all peninsular militias, and the power of the criollos increased as a result. The leaders of the plot, with the exception of Moreno, were exiled to Carmen de Patagones. Javier de Elío freed them and gave them political asylum at Montevideo. Cisneros government The Supreme Central Junta replaced Liniers with the naval officer Baltasar Hidalgo de Cisneros, a veteran of the Battle of Trafalgar, to end the political turmoil in the Río de la Plata. He arrived in Montevideo in June 1809 for the handover. Manuel Belgrano proposed that Liniers should resist on the grounds that he had been confirmed as Viceroy by a King of Spain, whereas Cisneros lacked such legitimacy. The criollo militias shared Belgrano's proposal, but Liniers handed over the government to Cisneros without resistance. Javier de Elío accepted the authority of the new Viceroy, and dissolved the Junta of Montevideo. Cisneros rearmed the disbanded peninsular militias, and pardoned those responsible for the mutiny. Álzaga was not freed, but his sentence was commuted to house arrest. There was concern about events in Spain and about the legitimacy of local governors in Upper Peru as well. On May 25, 1809, the Chuquisaca Revolution deposed Ramón García de León y Pizarro as Governor of Chuquisaca and replaced him with Juan Antonio Alvarez de Arenales. On July 16, the La Paz revolution, led by Colonel Pedro Domingo Murillo, deposed the Governor of
