After the capture of the Sumaca, the imperial merchant vessels no longer set sail without a convoy, but were always accompanied by vessels of war; and it became a difficult thing to capture them. The expeditions of the launches were, therefore, limited to a few cruises in the Lagoon, and with little success, as we were watched by the Imperialists, both by land and by water. In a surprise made by the chief, Francisco de Abrea, the whole of my band was near being cut off with its leader. We were at the mouth of the Camacua, with the launches drawn up on land, opposite the Galpon of Charginada,—that is, the magazine or depôt of the estancia, or large estate of that name. We were engaged in salting meat and collecting Yerba Matté, a species of tea, which grows in those parts of South America, and is used as their daily beverage by the inhabitants. The estate belonged to Donna Antonia, sister of the President. In consequence of the war, meat was not then salted there; and the Galpon was occupied only with Yerba Matté. We used the spacious establishment as our arsenal, and had drawn up our launches some distance from the water, between the magazine and the bank of the river, in order to repair them. At that spot were the shops of the smiths and laborers of the establishment, and there was a plentiful supply of charcoal; for although not then in use, the place retained something of its former condition and appearance. There were not wanting pieces of iron and steel, fit for different purposes in our little vessels. We could easily visit the distant estancias by a galloping ride, where we were most cheerfully supplied with whatever we found deficient in the arsenal. With courage, cheerfulness, and perseverance, no enterprise is impossible; and, for these I must do justice to my favorite companion and usual forerunner, John Griggs, who surmounted numerous difficulties, and patiently endured many disappointments, in the work of building two new launches. He was a young man of excellent disposition, unquestionable courage, and inexhaustible perseverance. Though he belonged to a rich family, he had devoted himself disinterestedly to the young Republic; and, when letters from his friends in North America invited him to return home, and offered him a very large capital, he refused, and remained until he sacrificed his life for an unhappy, but brave and generous, people. I had afterwards to contemplate the sad and impressive spectacle, presented by his death, when the body of my friend was suddenly cut down by my side.
