chunk: Acheron and Surprise are repaired; while Surprise will remain in the Galapagos, the captured Acheron is to be taken to Valparaíso. As Acheron sails away, Maturin mentions that their doctor had died months ago. Realising the French captain deceived him by pretending to be the ship's doctor, Aubrey gives the order to change course to intercept the Acheron and escort her to Valparaíso, and for the crew to assume battle stations. Maturin is again denied the chance to explore the Galapagos, but Aubrey wryly notes that since the bird he seeks is flightless, "it's not going anywhere", and the two play a selection of Luigi Boccherini as the crew assumes battle stations and the Surprise turns in pursuit of the Acheron.
