We reached Las Torres, the boundary of the two neighboring provinces, where we established our camp. The enemy contented themselves with being masters of the Lagoon, and did not proceed beyond. But, in combination with the division of Andrea, the division of Acunha advanced by the Serra, having recently come from the province of St. Paul, and being on the way for the Cima da Serra, (meaning the top of the mountains,) a department belonging to Rio Grande. The Serrans, overwhelmed by a superior force, asked assistance of General Canabarro; and he arranged an expedition for their aid, under the command of General Terceira. I, with my companions, formed a part of it; and, having joined the Serrans, who were under Colonel Acunha, we completely beat that division at Santa Victoria. The General was lost in the river Pelotas, and the greater part of his troops were made prisoners. That victory brought the three provinces of Lages, Vaccaria, and Cima da Serra, under the republic; and, a few days after, the conquerors entered Lages in triumph. In the meantime the invasion by the Imperialists had restored their party to power in the province of Missiones; and Colonel Mello, the Imperial General, had increased his corps in that province to about five hundred men. General Bento Manuel, who was to have fought him, was unable, because he had retreated; and he contented himself with sending Lieutenant-Colonel Portinhos in pursuit of Mello, who was marching in the direction of San Pablo. The position in which I was then placed gave us an opportunity not only to oppose Mello, but also to exterminate his force. But such was not the event. Colonel Terceira being uncertain whether the enemy would come by Vaccaria, or by the Caritibani, divided his forces into two, sending Colonel Aranha, with the good cavalry of the Serra, to Vaccaria, and marching towards the Caritibani with the infantry, and a part of the cavalry, chiefly composed of prisoners. It was by that point that the enemy approached. This division of the forces proved fatal. Their recent victory, the ardent feelings of the corps, and the information received concerning the enemy, which represented their numbers and spirit as less than they really were, led to their despising them too much. After a three days' march we reached Caritibani, and went round by the pass of Maromba, by which it was supposed the enemy would march. Guards were placed in the Pass, and at other points, where they were thought necessary. Towards midnight the guards at the pass were attacked, and compelled to retreat, so that they had scarcely time to escape after firing a few shots. From that moment until the break of day, the Republican troops stood ready for action; and it was not long after that hour that the enemy appeared, having crossed the river with their whole force, and drawn up near it ready for action.
