After cruising several days off the southern point designated in her orders, the Perry ran into Benguela. Spending a day in that place, she proceeded down the coast to the northward, occasionally falling in with British cruisers and legal traders. On meeting the Cyclops, the British commanding officer, in a letter, dated the 16th of July, stated to the commander of the Perry, that he “hastened to transmit, for his information, the following extract from a report just received from the commander of Her Britannic Majesty’s steam-sloop ‘Rattler,’ with copies of two other documents, transmitted by the same officer; and trusted that the same would be deemed satisfactory, as far as American interests were concerned.” The extract gave the information, that on the 2nd of July, Her Majesty’s steam-sloop Rattler captured the Brazilian brigantine “Volusia,” of one hundred and ninety tons, a crew of seven men, and fully equipped for the slave-trade, with false papers, and sailing under the American flag; that the crew had been landed at Kabenda, and that the vessel had been sent to St. Helena for adjudication; and that he also inclosed certified declarations from the master, supercargo and chief mate, stating the vessel to be bona fide Brazilian property; that they had no protest to offer, and that themselves and crew landed at Kabenda of their own free will and consent. On the following day, the commander of the Perry, in reply to the above communication, stated that, as the brigantine in question had first displayed American colors, he wished all information which could be furnished him in relation to the character of the papers found on board; the reason for supposing them to be false, and the disposition made of them. Also, if there was a person on board, apparently an American, representing himself, in the first instance, as the captain; and if the vessel was declared to be Brazilian on first being boarded, or not until after her capture had been decided upon, and announced to the parties in charge. In reply to this letter, on the 23d of July, the commanding officer of the British division stated that he would make known its purport to the commander who had captured the Volusia, and call upon that officer to answer the questions contained in the communication of the 17th instant, and hoped to transmit his reply prior to the Perry’s departure for the north coast. After cruising for several days in company with the English men-of-war, the vessel proceeded to Loanda, for the purpose of meeting the commodore. Arriving at that place, and leaving Ambriz without any guardianship for the morals of American traders, an order was transmitted to the acting first-lieutenant, to proceed with the launch on a cruise off Ambriz; and in boarding, searching, and in case of detaining suspected vessels, to be governed by the instructions therewith furnished him.
