Agreeably to orders from the navy department, the commander of the Peacock was required to proceed to the west coast of Sumatra, to ascertain whether Commodore Downes had obtained redress for the murders and robbery committed on board the ship Friendship, of Salem, by the natives of Qualah Battu; and if it should appear that from any cause such redress had not been effected, then the Peacock, in conjunction with the United States’ schooner Boxer, was to proceed to Qualah Battu, and, if possible, to obtain possession of the murderers, and transport them to the United States for trial; and also to demand indemnification for the heavy losses sustained by the owner. If these demands were not complied with, the town was to be destroyed. The Boxer not having yet joined us, orders were left for her commander to proceed to Bencoolen, in the island of Sumatra. On the evening of the twenty-fifth of June, the ship got under way, from the bay of Montevideo. As we slowly receded from the port, the feeble light on the mount shone like a distant star through the hazy atmosphere; and the thousand lights in the unfortunate town of San Felipé appeared like the glimmerings of the firefly in a midsummer’s night, revelling amid the light vapours arising from marshy ground; the brilliant light on the Flores also was in full view, throwing its extended beams far and wide over the tremulous sea. Our progress during the night was very slow--Flores and Lobos, and the serrated mountains of Maldonado, found us at the dawn of day, fanning along slowly, with an air which scarcely ruffled the ocean’s surface. Nothing occurred to us beyond what generally befalls the sons of the ocean, in running down ten thousand miles of coasting. Scarcely were we clear from the muddy waters of La Plata, and had launched amid the waves of the great Southern ocean, when squally weather assailed us, and close-reefed topsails were resorted to rather more frequently than is pleasant even to those who live upon the mountain-wave. The ship was at one time rolling her channels in before a strong westerly wind; at another, lying with her broadside deeply submerged by severe squalls from the northwestern quarter, the gun-deck being ankle-deep in water, and washing from side to side. _Life-lines_ were secured from gun to gun to support the constant passing of men fore and aft the deck. On the fifteenth of July, the snow-clad mountains of Tristan d’Acunha appeared, lighted by a brilliant morning-sun, and towering to a height estimated at between nine and ten thousand feet.
