At the same time jealousies broke out between the leaders. Moreno was worsted in a personal dispute with Saavedra, and at the beginning of the year 1811 was glad to accept an important mission to England. He died on the voyage thither. But the revolutionists were reminded that internal dissensions were out of place by the arrival at Montevideo of the able and energetic Elio, who had been appointed Viceroy by the Home Government. Although he was speedily forced to content himself with holding the town only, he was a source of great trouble to the Council and formed a valuable rallying-point for the loyalists. The Peruvian partisans also harassed them in the north, but Belgrano, by the victory of Tucuman on September 25th, laid the foundations of Argentine independence. The triumphant general wrote to Buenos Aires: "Our country may celebrate with just pride the complete victory obtained on the 25th of September, the anniversary of Our Lady of Mercy, whose protection we had invoked. We have captured seven guns, three flags, one standard, fifty officers, four chaplains, two curés, and six hundred men, besides four hundred wounded prisoners, the stores belonging to the infantry and the artillery, the largest part of the baggage. Such is the day's result. Officers and soldiers have behaved gloriously and bravely. We are pursuing the routed enemy." This victory freed the north from all fear of invasion in the future. There is no need to give details of the skirmishes with the royal forces or the skirmishes between intriguing leaders which occupied the next eighteen months. It is sufficient to say that during this time the influence of the soldier San Martin was growing rapidly, and towards the close of the year 1813 he replaced Belgrano as commander of the northern army. Hitherto power had been in the hands of two or three men, among whom Alvear was now the most prominent; but in January, 1814, a Congress assembled at Buenos Aires, and on the 31st of that month it chose Posadas, a relation of Alvear, to be Dictator of the so-called United Provinces. In June Alvear captured Montevideo, and the hopes of Spain in the Plate district were for ever quenched; but Uruguay refused to be subordinate to Buenos Aires, and Posadas was in no position to coerce her. Uruguay, therefore, finally severed the connection with Argentina, and passes out of our history. Meanwhile San Martin, who had become Governor of Mendoza, was carrying on that campaign for the liberation of South America which was to make his name immortal; but in Buenos Aires affairs were going by no means well--in fact, anarchy reigned. The appointment of Puirredon as Dictator brought about some improvement, and on July 9, 1816, the separation from Spain was formally announced.
