There he sighted another hostile privateer, the Golden Eagle, larger than his own ship. Instead of shifting his course to avoid her, Haraden clapped on sail and steered alongside after nightfall, roaring through his trumpet: "What ship is this? An American frigate, sir. Strike, or I'll sink you with a broadside." Dazed by this unexpected summons in the gloom, the master of the Golden Eagle promptly surrendered, and a prize crew was thrown aboard with orders to follow the Pickering into Bilbao. While just outside that Spanish harbor, a strange sail was descried and again Jonathan Haraden cleared for action. The vessel turned out to be the Achilles, one of the most powerful privateers out of London, with forty guns and a hundred and fifty men, or almost thrice the fighting strength of the little Pickering. She was, in fact, more like a sloop of war. Before Captain Haraden could haul within gunshot to protect his prize, it had been recaptured by the Achilles, which then maneuvered to engage the Pickering. Darkness intervened, but Jonathan Haraden had no idea of escaping under cover of it. He was waiting for the morning breeze and a chance to fight it out to a finish. He was a handsome man with an air of serene composure and a touch of the theatrical such as Nelson displayed in his great moments. Having prepared his ship for battle, he slept soundly until dawn and then dressed with fastidious care to stroll on deck, where he beheld the Achilles bearing down on him with her crew at quarters. His own men were clustered behind their open ports, matches lighted, tackles and breechings cast off, crowbars, handspikes, and sponge-staves in place, gunners stripped to the waist, powder-boys ready for the word like sprinters on the mark. Forty-five of them against a hundred and fifty, and Captain Haraden, debonair, unruffled, walking to and fro with a leisurely demeanor, remarking that although the Achilles appeared to be superior in force, "he had no doubt they would beat her if they were firm and steady and did not throw away their fire." It was, indeed, a memorable sea-picture, the sturdy Pickering riding deep with her burden of sugar and seeming smaller than she really was, the Achilles towering like a frigate, and all Bilbao turned out to watch the duel, shore and headlands crowded with spectators, the blue harbor-mouth gay with an immense flotilla of fishing boats and pleasure craft. The stake for which Haraden fought was to retake the Golden Eagle prize and to gain his port. His seamanship was flawless. Vastly outnumbered if it should come to boarding, he handled his vessel so as to avoid the Achilles while he poured the broadsides into her. After two hours the London privateer emerged from the smoke which had obscured the combat and put out to sea in flight, hulled through and through, while a farewell flight of crowbars, with which the guns of the Pickering had been crammed to the muzzle, ripped through her sails and rigging.
