The orders being largely discretionary, and the Chatsworth still in port, and suspected of the intention of shipping a cargo of slaves at Ambriz, the Perry sailed, the day on which her orders were received, without giving any intimation as to her cruising-ground. When outside of the harbor, the vessel was hauled on a wind to the southward, as if bound up the coast, and continued beating until out of sight of the vessels in the harbor. She was then kept away to the northward, making a course for Ambriz, in anticipation of the Chatsworth’s soon sailing for that place. The cruising with the English men-of-war was resumed. A few days after leaving Loanda, when trying the sailing qualities of the vessel with a British cruiser, a sail was reported, standing down the land towards Ambriz. Chase was immediately made, and, on coming within gun-shot, a gun was fired to bring the vessel to. She hoisted American colors, but continued on her course. Another gun, throwing a thirty-two pound shot across her bows, brought the Chatsworth to. She was then boarded, and again searched, without finding any additional proof against the vessel’s character. After remaining a day or two off Ambriz, the Perry proceeded to Ambrizette, a short distance to the northward, leaving one of the ship’s boats in charge of an officer, with orders to remain sufficiently near the Chatsworth, and, in case she received water-casks on board, or any article required to equip a slave-vessel, to detain her until the return of the Perry.
