In the night of the 1st of November, eighty men, chosen from the army, passed the river, amongst whom figured some grenadiers of the regiment of Estremoz; and whose chief was a brave ensign, well known by his surname of Padilha. Part of them took up a position in a wood; others proceeded a little way up the river, keeping near its banks, in order to give more prompt succour to the first on the signal of attack, which began in the morning, against those who first entered the plain. The assailants, together with thirty Spaniards, who came to their succour, were put to flight, but immediately returned in larger numbers, with three field pieces, with which they laboured to open out both their wings. However, the Portuguese did not give them time for a second discharge, but falling intrepidly upon them, they put them to the rout, taking their cannon, nine prisoners, and leaving fifteen dead upon the field. On the 23d of the same month, almost at midnight, a cannon was discharged in the Passo dos Barros, which is about three leagues below St. Borja, where it was heard; and from whence afterwards arrived an Indian, living in that neighbourhood, with information to the Portuguese, that the Spaniards were stationed in the woods, near the same pass. They remained the rest of the night under arms. The following morning Captain Joze Borges do Canto put himself in march for this point, with his company and some others, amounting to one hundred and ten men; and finding the Spaniards entrenched in the woods on the banks of the river, and not discovering any advantageous mode of attacking them, sent his lieutenant with thirty men dressed in white according to the Indian fashion, which marching at a great distance from the Spaniards, and having gained their rear, began firing upon them. The first discharges were the signal for the captain to invest the fortification, which was abandoned without any resistance, the Spaniards leaving seventy-four prisoners. Such was the success of the campaign, on the part of the Portuguese, in this district, and the mode by which the Portuguese crown possessed itself of the province of the Seven Missions, which made a part of that of Rio Grande de St. Pedro, until a governor was named to it. It is confined on the north by that of St. Paulo; on the west by that of Paranna; and on the south and east by the province of Rio Grande de St. Pedro. MOUNTAINS.--St. Martinho, the most elevated portion of the serra, which serves for its eastern limits, and the mountain of St. Luiz, in the vicinity of the town of its name, are the most remarkable mountains.
