Dr Jacob learns the corsair has two galleys to act as decoys whilst he lies under Tarifa before running through the Strait. The "Surprise", "Ringle" and the blue cutter lie in wait in the Strait. The galley sees three armed ships, and Murad Reis, her captain, fires on the frigate, destroying one gun, and killing Bonden, the coxswain, as well as Hallam, a midshipman. After a long pursuit, the galley hides at Cranc (Crab) island, where "Surprise" and "Ringle", unable to follow the galley into the shallow lagoon, block the exit. A gun from the "Surprise" is hoisted up a cliff, where it can fire unopposed on the galley. The galley's crew, seeing the situation is hopeless, behead Murad and surrender. Returning victorious to Gibraltar, the "Surprise" sees the town exploding fireworks, and learns that Napoleon has lost in the Low Countries, fully beaten. Ali Bey sends word he wants the gold; he is killed and the new Dey, Hassan, admits the xebec fired first, and asks for a loan to consolidate his position in Algiers. The xebec is cleaned up and sent to Algiers, while the gold is shared out in Gibraltar. Barmouth worries that his new wife is too friendly with Aubrey, so he sends him off to the venture in Chile.
