Though his favourite general, Marshal Caxias, was a Conservative, and not on good terms with the Liberal Cabinet, the Emperor insisted that he be sent to take command. Re-enforcements were vigorously recruited from all over the empire, and in July, 1867, the cautious Caxias began a slow advance. The expenses were mounting up to sixty millions a year; the country chafed at the delays, Caxias quarrelled with the ministers. In July, 1868, the Emperor dismissed them on his own responsibility, and, though the Liberals had still a large majority in the Chamber, called in a Conservative Cabinet. On this occasion the Emperor's pressure was not influential enough to change a minority into a majority, and the Chamber preferred dissolution to submission. Meanwhile Caxias had at last begun to win victories. The very month of the fall of the Liberals he took the great fortress of Humaita, which guarded the passage up the Paraguay, and Lopez retreated to the neighbourhood of his capital accompanied by almost all the surviving Paraguayans. In November Caxias cleverly outflanked him and taking him in the rear compelled him to fight outside of his trenches until hardly any Paraguayans were left. By the beginning of 1869 Lopez was a fugitive, the Brazilians were in possession of Asuncion, and the war was over except for pursuing Lopez and the few starving soldiers who followed him through the woods. [Illustration: HOSPITAL AND OLD CHURCH AT PORTO ALEGRE.] Elections were held in March, but it was not worth while for the Liberals to make even the show of a contest. The Liberal leaders issued a manifesto declining to take any part, and, censuring the Emperor for calling the Conservatives to power against the known wishes of the majority of a legally elected Chamber, announced that they would respect the laws and would confine themselves to a non-parliamentary propagation of the doctrines of anti-absolutism, liberalism, and emancipation. From this time dates the systematic propaganda for the republic. The war ended with the Emperor's son-in-law hunting down the Paraguayan bands. In March, 1870, Lopez was caught with the last few hundred men who remained faithful and speared by a common soldier as he tried to escape through the woods.
