 By this point , the only military support for Moreno was Domingo French , head of " The Star " regiment . Castelli and Belgrano supported him , but were far away from the capital on their respective military campaigns . The activists of the May Revolution supported him as well , as did other members of the Junta and other patriots like Vieytes and Nicolás Rodríguez Peña . Saavedra kept the strong support of the Regiment of Patricians , and added that of the merchants and even some supporters of the former regime who deemed the moderated Saavedra a lesser evil . Moreno sought to modify the military balance of power by reforming the promotion rules . Up until that point , the sons of officials were automatically granted the status of cadet and were promoted just by seniority ; Moreno arranged that promotions were earned by military merits instead . However , in the short run this measure worked against him , as it antagonised members of the military who got promoted precisely because of such rules . He also thought that support from the lower classes was instrumental to the success of the Revolution , and wrote letters to Chiclana instructing him to generate such support at Upper Peru . Such popular involvement would take time to consolidate : the Guerra Gaucha , the War of the Republiquetas , and the rise of José Gervasio Artigas took place later , not as of 1810 .
