“Inclosed are affidavits, with other papers and letters, in relation to the seizure of the American brigantine Chatsworth. This has been an exceedingly complicated case, as relating to a slaver with two sets of papers, passing alternately under different nationalities, eluding detection from papers being in form, and trading with an assorted cargo. “The Chatsworth has been twice boarded and searched by the commander, and on leaving for a short cruise off Ambrizette, a boat was dispatched with orders to watch her movements during the absence of the Perry. On returning from Ambrizette, additional evidence of her being a slaver was procured. Since then the affidavits of the master of the Chatsworth and the mate of the Louisa Beaton have been obtained, leading to further developments, until the guilt of the vessel, as will be seen by the accompanying papers, is placed beyond all question.” The Italian supercargo, having landed most of the cargo, and his business being in a state requiring his presence, was permitted to go on shore, with the assurance that he would return when a signal was made. He afterwards came within hail of the Chatsworth, and finding that such strong proofs against the vessel were obtained, he declined going on board, acknowledging to the master of the Louisa Beaton that he had brought over Brazilian papers. The crew of the Chatsworth being foreigners, and not wishing to be sent to the United States, were landed at Ambriz, where it was reported that the barracoons contained four thousand slaves, ready for shipment; and where, it was said, the capture of the Chatsworth, as far as the American flag was concerned, would give a severe and an unexpected blow to the slave-trade. After several unsuccessful attempts to induce the supercargo of the Chatsworth to come off to that vessel, a note in French was received from him, stating that he was “an Italian, and as such could not be owner of the American brig Chatsworth, which had been seized, it was true, but unjustly, and against the laws of all civilized nations. That the owner of the said brig would know how to defend his property, and in case the judgment should not prove favorable, the one who had been the cause of it would always bear the remorse of having ruined his countryman.” After making the necessary preliminary arrangements, the master, with a midshipman and ten men, was placed in charge of the Chatsworth; and on the 14th of September, the following order was sent to the commanding officer of the prize: “You will proceed to Baltimore, and there report yourself to the commander of the naval station, and to the Secretary of the Navy. You will be prepared, on your arrival, to deliver up the vessel to the United States marshal, the papers to the judge of the United States District Court, and be ready to act in the case of the Chatsworth as your orders and circumstances may require.
