The Brazilian land forces in Uruguay were increased to twenty thousand, but the Argentines under General Carlos Alvear audaciously averted the danger of an invasion of their territory by planning and effecting an inroad into Rio Grande itself. The Brazilian general allowed Alvear to slip between his main body and Montevideo, and the latter penetrated to the East, sacked the important town of Bage, and was off to the North with the whole Brazilian army in hot pursuit. On the 20th of February, 1827, the Argentines turned and attacked the Brazilians at a disadvantage, defeating them with great loss. In this battle of Ituzaingo sixteen thousand men took part, and the armies were nearly equal in numbers. The Brazilians escaped without serious pursuit, while the Argentines retired at their leisure, assured that no aggressive operations would soon be undertaken against them. Pedro's hope of dominance on the south shore of the Plate was ended. Naval disasters suffered at the hands of the indefatigable Brown made him still more anxious for peace. Negotiations were begun with the Argentine government which was only prevented by lack of money and internal factional quarrels from undertaking an aggressive war against Brazilian territory. Operations were kept up languidly on both sides for a year, and finally Pedro in 1828 consented to a preliminary treaty by which he relinquished his sovereignty over Uruguay, obtaining in return Argentine consent that it be erected into an independent country. The first session of the Brazilian Congress had been very timid and voted as the Emperor desired. The session of 1827 was not so respectful; the news of Ituzaingo had made him seem less formidable. For the first time the chamber became a forum for the discussion of governmental theories, and the voice of Vasconcellos, the great champion of parliamentary government, was heard. In the fall of 1827 independent newspapers began to make their appearance and Pedro dared not interfere with them. The tone of most of them was exaggerated, but in December the _Aurora Fluminense_, with Evaristo da Veiga as editor, issued its first number. By universal consent he is recognised as the most influential journalist who ever wielded a pen in Brazil. His profound and temperate discussions of public affairs gave him an ascendency over opinion which can hardly be understood in countries where party conventions and set speeches give opportunities for authoritatively outlining policies.
