Buenos Aires requested the other cities in the viceroyalty to acknowledge the new Junta and send deputies. The precise purpose of these deputies, join the Junta or create a congress, was unclear at the time and generated political disputes later. The Junta was initially resisted by all the main locations around Buenos Aires: Córdoba, Montevideo, Paraguay and the Upper Peru. Santiago de Liniers came out of his retirement in Córdoba and organized an army to capture Buenos Aires, Montevideo had naval supremacy over the city, and Vicente Nieto organized the actions at the Upper Peru. Nieto proposed to José Fernando de Abascal y Sousa, viceroy of the Viceroyalty of Peru at the North, to annex the Upper Peru to it. He thought that the revolution could be easily contained in Buenos Aires, before launching a definitive attack.
