The sole hope of Artigas now lay in the provinces of Entre Rios and Corrientes. Even here had occurred a wavering that had necessitated a crushing by force ere a return to allegiance had been brought about. With these and the remaining Oriental forces he continued the struggle. But the tide of his fortune had turned. The beginning of the year 1818 witnessed the capture of two of his foremost lieutenants, Otorgues and Lavalleja, who were sent by the Portuguese to an island in the Bay of Rio de Janeiro. As a last effort, Artigas, daring the aggressive even at this stage, hurled his intrepid Gauchos and Misiones Indians once more over the frontier into Brazilian territory itself. A brilliant victory was followed by the inevitable retreat in the face of immensely superior forces. At Tacuarembo, in the north of the Banda Oriental, fell the blow that virtually ended the campaign. Here Artigas's army, under the command of Latorre, was surprised and completely routed with a loss that left the force non-existent for practical purposes. Shortly after this Rivera surrendered to the Portuguese, and with his submission went the last hope of success. Artigas crossed the River Uruguay, and took up a position in Entre Rios. The hour of his doom had struck; but even then, with his forces shattered and crushed, he refused to bow to the inevitable. With extraordinary doggedness he scoured Entre Rios, Corrientes, and Misiones in an endeavour to sweep up the remaining few that the battles had spared, and yet once again to lead them against the Portuguese. But on this occasion there was no response. Sullen and despairing, the majority of the remnant turned from him, and in the end his officer Ramirez, Governor of Entre Rios, threw off his allegiance, and came with an expedition to expel him from the country. Devoting themselves to this narrowed campaign, the two Gaucho leaders assailed each other with fury. Victory in the first instance lay with Artigas, despite his diminished following. Ramirez, however, received reinforcements from the Buenos Aires authorities, who had thrown the weight of their influence against their old enemy. It was against the allied forces that Artigas fought his last battle. When it was evident even to his indomitable spirit that all hope was at an end he marched northwards with a couple of hundred troops who remained faithful in the hour of adversity to the once all-powerful Protector. At Candelaria he crossed the Paraná, and sought the hospitality of Gaspar Rodriguez Francia, the dreaded Dictator of Paraguay. The latter first of all imprisoned the fugitive--probably more from force of habit than from any other reason, since Francia was accustomed to fill his dungeons as lightly as a fishwife her basket with herrings.
