The Yellow Admiral is the eighteenth naval historical novel in the Aubrey-Maturin series by English author Patrick O'Brian, first published in 1996. The story is set in the era of the Napoleonic Wars.

The ships of his squadron are dispersed by the Admiralty as Aubrey's two missions (to the slave coast of Africa and up to Ireland's west coast) were completed and Aubrey is no longer a commodore. Captain Aubrey is left in command of HMS Bellona. He sails her on blockade duty around Brest, France, under an admiral who dislikes him for actions on land and makes trouble for Aubrey in the Royal Navy. On land, he is settled in Woolcombe, the family estate, where he has powers as lord of the manor. Aubrey's financial troubles are eased by his capture of a prize. Dr Maturin retrieves his family but not his fortune, and they settle in an empty wing of the Aubrey's family estate. As the war against Napoleon looks to be ending, Maturin works out a plan to keep Aubrey at sea on his privately owned ship Surprise to chart Chile's coast, while Maturin aids the Chilean independence movement. Aubrey suspends himself from the Navy List to avoid the worst career fate, being yellowed, set aside with no squadron of his own, until his reputation can be salvaged, to which end, Napoleon lends a hand by restarting the war.

Critical reception varied, from "taking his readers for granted", "an interim novel" or "somewhat predictable, nonetheless full of life" to "another excellent adventure" and "the top of his elegant form". As often happens, reviewers comment on the whole series to date ("virtuosity", "the best things of their kind", "uniquely excellent", "as always lapidary prose"), and are glad this is not the last book in the series, there is more to come, recommending readers new to the series to start it from the first novel. Aubrey's relationship with his wife is noted as a strong point of this novel, as is the sly humour and some of the "set pieces", like the boxing match and actions at sea during the blockade.

Plot summary

Aubrey, captain of HMS Bellona in the Brest blockade after his squadron was dispersed, is home at Woolcombe, the Aubrey family estate, on parliamentary leave. Three lawsuits from owners of slave ships captured on his mission along the West African coast tie up his funds. His wife Sophia rents out Ashgrove Cottage, their marital home. Maturin returns from Spain with his wife Diana and their household, moving into an empty wing of Woolcombe. Maturin's vast wealth is tied up in Spain, where authorities, informed by Jean Dutourd, are displeased at his activities in Peru, a Spanish colony. On land, Aubrey opposes the enclosing of the common, Simmons Lea, which has been proposed in the House by his neighbour, Captain Griffiths. Aubrey has power as lord of the manor, which he uses when the bill is called. Admiral Stranraer on the Brest blockade encouraged this enclosure, and he is uncle to Griffiths. The Admiral calls Aubrey back aboard, hoping to prevent his appearance in Parliament. Quick action on the part of Diana and Clarissa Oakes foils this scheme. Aubrey is watching a boxing match between Barret Bonden and Evans, Griffith's gamekeeper, when the orders arrive at Woolcombe. Mrs Oakes appears at the match to tell Aubrey to proceed directly to Parliament. Stranraer is displeased when Aubrey reveals the committee's decision; he sends HMS Bellona to the inshore blockading-squadron. Aboard the flagship, Maturin receives letters for his covert mission in France. The Admiral tries unsuccessfully to use Maturin to change Aubrey's mind.

At the dark of the moon in heavy fog, Aubrey puts Maturin ashore in France with the Catalan agent, Inigo Bernard. Apparently at the same time, two French ships slip through the blockading squadron in the sector that HMS Bellona patrols. The Admiral rebukes Aubrey, who accepts no blame, and returns Bellona to the offshore squadron. Aubrey receives a letter from Sophie, in which she accuses him of adultery and announces her intention of leaving him, having read letters sent him from Canada by Miss Amanda Smith. Aubrey is spoiling for a fight. During manoeuvres in foggy weather the Bellona spots a French privateer chasing a merchantman. She signals to the fleet, and proceeds to take Les Deux Frères, which proves a rich prize, having captured two Guinea coast merchant ships. A storm batters the Bellona, so Aubrey takes the ship for repair in Cawsand Bay. At Woolcombe, Aubrey asks Sophie for forgiveness, but she rebuffs him. Aubrey sends his tender Ringle to report Bellona's condition to the Admiral. The Admiral then sends Ringle to retrieve Maturin from France. Once Bellona is repaired, Aubrey rejoins the blockading squadron, learning that Ringle has taken Maturin to England. In London, Maturin tells Sir Joseph Blaine about a plot by a Spanish intelligence officer to burgle Blaine's house. With the assistance of Mr Pratt, they capture the Spanish agent red-handed. Maturin updates Sir Joseph on the readiness of Chile for independence. They devise a scheme for an expedition led by Aubrey on the Surprise. The negative reports from Lord Stranrear with the war winding down put Aubrey in the position of being promoted to rear admiral without a squadron, known informally as being admiral of the yellow; as there is no yellow squadron, it is the worst career fate. Maturin learns his fortune is again available to him. In a gesture to his shipmates, Maturin buys new clothes.

Maturin goes to Woolcombe, where Diana tells him of the issue between Sophie and Jack. She and Clarissa have enlightened Sophie as to the possibility of enjoying sex, even suggesting that she have her own affair. Sophie writes a letter of reconciliation to her husband, which Maturin carries aboard. The letter leaves Aubrey joyous. Admiral Stranraer requests Maturin's medical advice; Maturin suggests use of medicines unfamiliar to the flagship's surgeon, to good effect. Bellona finds the inner squadron fighting two French ships of the line. Upon seeing the Bellona and Grampus, the French ships retreat. For months, the Bellona sweeps the bay, blockading Brest. Maturin tells Aubrey of his plan for Chile, to which Aubrey agrees. Queen Charlotte comes to visit the inner squadron, with a stores ship to replenish food. The Admiral thanks Maturin for his treatment. The Admiral informs his captains of the progress in the war on land, where Napoleon is making errors and peace talks are underway but not yet successful.

The peace is announced; Napoleon is exiled to Elba. The crew of the Bellona are paid off and the ship goes into ordinary storage. Aubrey and Maturin read newspapers to learn world events while they were blockading Brest, and adjust to peace. They agree to a plan with three men from the Chilean independence movement. Aubrey requests suspension from the Navy List, and is put on loan to the hydrographic office. Maturin finances the fitting-out of the Surprise, which takes until February 1815. They sail to Madeira with their families aboard. After a brief time on the island, their families will take the packet home. Unexpectecly, Lord Keith, commander-in-chief in the Mediterranean, sends orders to Aubrey reinstating him because Napoleon has escaped from Elba. Aubrey takes command of the Royal Navy ships in the harbour of Madeira to blockade the Straits of Gibraltar.
