Desolation Island recap

Jack Aubrey takes command of the ageing Leopard to carry convicts, troops, and passengers to New South Wales. Stephen Maturin uses the voyage to watch the American agent Louisa Wogan and feed deceptive intelligence into her network; her young American admirer Michael Herapath has secretly followed her aboard. A gaol fever spreads from the prisoners and devastates the crowded ship, forcing Stephen and Herapath into exhausting medical work. In southern waters the Dutch seventy-four Waakzaamheid pursues Leopard through a prolonged gale. Jack finally turns to fight, and a huge sea overwhelms the Dutch ship. Leopard then strikes ice, is nearly lost, and can barely steer. After deepening conflict with Jack, Lieutenant Grant departs in boats with part of the company. Jack reaches remote Desolation Island, where the survivors repair the damaged ship sufficiently to resume the voyage. Leopard sails east with a diminished crew, Grant missing, and Stephen's intelligence deception still in motion.

Previously: Jack Aubrey advanced from his first command to post-captain and then commodore, combining brilliant seamanship with recurring periods of debt and official neglect. He married Sophia Williams and now has a young family. Stephen Maturin, his closest friend and frequent surgeon, is also a British intelligence agent whose work has shaped several of Jack's appointments. Stephen remains emotionally attached to Sophia's cousin Diana Villiers, who left British society in the company of the wealthy American Johnson. Jack's Mauritius expedition captured Réunion and Mauritius after early gains, a disastrous British defeat at Grand Port, and a renewed invasion. The victory strengthened Jack's reputation, while Stephen's secret work helped remove an important French base in the Indian Ocean.

After the Mauritius campaign, Jack enjoys family life and improved circumstances but soon accepts command of Leopard, an old ship assigned to transport convicts and other passengers to New South Wales. The commission is less glamorous than a frigate command, yet it offers employment and a long independent voyage. Stephen joins as surgeon with a separate intelligence purpose. One prisoner, the American Louisa Wogan, is believed to have served as an agent, and British intelligence wants misleading material to pass through her communications. Leopard's company is crowded and uneven, with prisoners below, soldiers and naval hands aboard, and officers including the strong-minded first lieutenant James Grant. A young American, Michael Herapath, has also hidden aboard in order to remain near Wogan, creating both a disciplinary problem and a possible channel into her confidence.

Leopard has begun the long transport passage with convicts, troops, passengers, and an unsettled naval company packed together. Stephen observes Louisa Wogan while concealing the intelligence plan to let carefully false information reach American hands. Michael Herapath is discovered aboard; his connection to Wogan is obvious, but his education and willingness to assist Stephen give him a practical place in the ship. Disease then emerges among the prisoners. The enclosed convict quarters turn infection into a shipwide crisis, and ordinary divisions of rank and status matter less as patients multiply. Stephen imposes isolation and treatment with limited means, helped by Herapath and by the officers who remain fit. Deaths reduce the company and transform the voyage from an awkward transport duty into a struggle to keep enough healthy people to work the ship.

Leopard's voyage has already been reshaped by epidemic: illness originating among the convicts has killed many people and left the ship short-handed. Stephen and Michael Herapath have worked together among the sick, while Stephen continues his guarded effort to place deceptive intelligence within Louisa Wogan's reach. As Leopard moves into harsher southern waters, a Dutch ship of the line, Waakzaamheid, begins a determined pursuit. The enemy is far more heavily armed, so Jack's only realistic defence is distance, weather, and superior handling. The chase stretches through dangerous seas. Sail is carried under pressures that test spars, rigging, and the weakened company, while Grant's professional doubts about Jack's willingness to risk the ship sharpen. By the chapter's end escape has not been secured, and the Dutch ship continues to close whenever conditions favour her.

The gaol fever has diminished Leopard's people, and Waakzaamheid has pursued the ship deep into the southern ocean. Unable to run indefinitely, Jack chooses a moment in extreme weather to turn and use Leopard's guns against her much larger enemy. The engagement coincides with a mountainous sea that strikes the Dutch ship disastrously; Waakzaamheid is overwhelmed and disappears with her entire company. Leopard escapes capture but not danger. Soon afterward she collides with ice and suffers severe damage below the waterline as well as the loss of effective steering. Pumps, jury arrangements, and unremitting labour keep her afloat. The disagreement between Jack and Grant becomes a crisis of command. Grant leaves in boats with a group of men, choosing the uncertain open sea over continuing in the crippled ship. Jack is left to find land with fewer hands and no margin for another failure.

Leopard sailed for New South Wales with convicts and an intelligence operation aboard, lost many people to gaol fever, and survived the Dutch Waakzaamheid only when a huge sea destroyed the pursuing ship during Jack's counterattack. Ice then left Leopard leaking and nearly unsteerable. After his long disagreement with Jack, Lieutenant Grant departed in boats with part of the company and remains missing. Jack nevertheless brings the remaining people to the bleak refuge of Desolation Island. In sheltered water they repair the hull and improvise enough control to make another passage possible. Stephen takes what opportunities the island offers for natural history, but he also keeps Louisa Wogan and the false intelligence scheme in view; Michael Herapath's loyalty to her remains the likely path by which the planted information will travel. Leopard finally leaves the island heading east, still bound for New South Wales, reduced in strength but no longer trapped.

Leopard survives the southern-ocean chase only because Jack turns on the far more powerful Waakzaamheid at the instant a great sea makes the Dutch ship vulnerable; the pursuer is overwhelmed and sinks with all hands. Survival is followed by collision with ice, grave structural damage, and the loss of normal steering. Lieutenant Grant eventually leaves in boats with a party of men rather than continue under Jack's decisions, and their fate remains unknown. Jack brings the leaking, undermanned Leopard into shelter at remote Desolation Island. The crew uses the anchorage and local resources to repair the hull and contrive the means to sail again. Stephen's intelligence operation around Louisa Wogan has continued amid epidemic and shipwreck conditions, with false information placed where the American network may carry it. Leopard leaves the island capable of continuing east toward New South Wales, but she is badly reduced, Grant and his followers are missing, and Jack's commission remains an unfinished passage rather than a completed voyage.
