The Surgeon's Mate characters

Appears from the start

A Royal Navy post-captain recovering from the wound he received during Java's defeat. Newly freed from American captivity, he remains an energetic fighting officer whose instinct for seamanship is stronger than his patience with politics or secrecy.

Appears from the start

Jack's close friend and surgeon, also a naturalist and a British intelligence agent. He has escaped Johnson's pursuit in Boston and is reunited with Diana Villiers, but his secret work continues to place both of them in danger.

Appears from the start

Sophia Aubrey's cousin, recently brought out of Boston after leaving the American intelligence chief Johnson. Independent and socially assured, she and Stephen have renewed their long, difficult attachment without yet deciding what form their future will take.

Commander of HMS Shannon, whose disciplined crew captured Chesapeake and carried Jack, Stephen, and Diana to Halifax. He is recovering from the severe head wound he received in that action.

The young American who followed Louisa Wogan aboard Leopard and later helped Stephen in Boston. His gratitude and local connections contributed to the fugitives' escape, and he remains friendly to them in Halifax despite the war.

A younger naval officer long known to Jack, lively, capable, and personally loyal. He helps Jack and his companions during the passage back into British service.

Jack's wife and Diana's cousin, waiting in England with the Aubrey children. Her affection and practical domestic loyalty give Jack a secure home even when naval employment repeatedly takes him away.

Also known as Jagiello

First appears in chapter 4

A handsome young Lithuanian cavalry officer attached to Stephen's Baltic mission. Cheerful, brave, and linguistically useful, he adapts readily to naval life and accompanies Stephen ashore where a conventional British officer would attract attention.

First appears in chapter 6

The Catalan commander of an isolated garrison in the Baltic. His men have broken with French authority, leaving him to balance their safety, his political convictions, and the uncertain value of British promises.

First appears in chapter 9

A French intelligence officer involved in the treatment of important British prisoners. He understands that Stephen may be more than a naval surgeon and approaches the captives as sources of political information rather than ordinary prisoners of war.

First appears in chapter 4

Jack's trusted coxswain, a former prizefighter and exceptionally able seaman whose loyalty has survived changes of ship and fortune.

First appears in chapter 4

Jack's sharp-tongued steward, protective of his captain's possessions and routines and accustomed to serving through disorder at sea.
