The Pilot made the African coast near Benguela; and afterwards anchored at Bahia Longa, where, there being no slaves ready for shipment--as eight hundred had been, a few days previously, shipped in a two-topsail schooner--she was ordered, by the slave-agents, to remain at sea for ten days. On making the land at the expiration of that time, the English steamers Fire Fly, Star, and Pluto, being at Ambriz, she was again ordered to sea for ten days; when, on anchoring at the latter place, she was captured by the English steamer Cyclops. She was to have shipped twelve hundred slaves, who had been for some time ready for a slave-steamer--then so strictly blockaded at Santos by the English steamer Hydra, as to prevent her leaving port. Such was the information contained in this letter. During this correspondence with the British officers, the Perry was cruising off Ambriz, in company with a part of the British squadron, for the purpose of boarding and searching all American vessels suspected of being engaged in the slave-trade, on that part of the coast. After cruising for several days, the commander-in-chief of the British naval forces, bearing his pendant at the main of the steam-frigate Centaur, appeared in the offing. The Perry hauled up her courses, and saluted him with thirteen guns, which were duly returned. An official call was made on the commodore, and an arrangement settled for the joint cruising of the Perry and steamer Cyclops. This cruising had continued for a week or more, when the arrival of the U. S. sloop-of-war John Adams constituted her commander the senior American officer south of the equator; he, accordingly, while in company, relieved the Perry of the correspondence with the British officers. A short time after the arrival of the Adams, it became necessary for her to visit Loanda, when the Perry was again left with the Cyclops, cruising off Ambriz. [5] The papers of the second slaver captured by the Perry were in form, excepting the crew list, which showed but one American on board, who was master of the vessel. And in a letter of instructions from the reputed owner, he was required to leave whenever the Italian supercargo directed him to do so. This shows how readily the nationality of a vessel may be changed. [6] The master of the first slaver captured by the Perry, stated that had he not supposed she was an English cruiser, he would have been prepared with a foreign flag, and otherwise, to have eluded search and capture; and that on a former occasion he had been boarded by an English cruiser, when, to use his own expression, he “bluffed off John Bull with that flag;” referring to the American ensign.
