The three vessels which were armed, and destined to make an excursion on the ocean, were the Rio Pardo, which was under my command, and the Casapava, under Griggs—both schooners—and lastly, the Seival, which had come from Rio Grande, commanded by the Italian, Lorenzo. The mouth of the Lagoon was blockaded by Imperial vessels of war; but we went out by night, without falling in with any of them, and steered north. When we had reached the latitude of Santos, we met an Imperial corvette, which chased us two days in vain,—when we approached the Island of Abrigo, where we captured two Sumacas. This is a kind of vessel, so named by the Brazilians, being a sort of sloop. We then proceeded on the cruise, and took several other prizes. After eight days' sailing we returned towards the Lagoon. I had conceived a singular presentiment of the state of things in that region, because, before my departure, the people of St. Catherine's had begun to show a bad humor, and it was known that a strong corps of troops was approaching, commanded by General Andrea, who was famous for precipitation, and his atrocious system of warfare, which made him much feared. When off St. Catherine's, on our return, we met a Brazilian patachio, which is a sort of brig-schooner,—the Rio Pardo and the Seival being together, the Casapava having parted company a few nights before, when it was very dark. We were discovered; and there was no escape. We therefore attacked them, and opening a fire. The enemy replied bravely; but the action could produce but little effect, because the sea was very rough. The result, however, was the loss of several of our prizes, the commanders of some of which, being frightened by the superior force of the enemy, struck their flags, while others steered for the neighboring coast. Only one of the prizes was saved, that commanded by the brave Ignacio Bilbao, which went ashore in the port of Imbituba, and remained in our possession. The Seival had her gun dismounted in the engagement, and having sprung a leak, took the same direction, and I was obliged to abandon the prizes.
