Beat to quarters: June 1808, somewhere west of Nicaragua-a site suitable for spectacular sea battles. The Admiralty has ordered Captain Horatio Hornblower, now in command of the thirty-six-gun HMS Lydia, to form an alliance against the Spanish colonial government with an insane Spanish landowner; to find a water route across the Central American isthmus; and "to take, sink, burn or destroy" the fifty-gun Spanish ship of the line Natividad or face court-martial. A daunting enough set of orders-even if the happily married captain were not woefully distracted by the passenger he is obliged to take on in Panama: Lady Barbara Wellesley.

Ship of the line: May 1810, seventeen years deep into the Napoleonic Wars. Captain Horatio Hornblower is newly in command of his first ship of the line, the seventy-four-gun HMS Sutherland, which he deems "the ugliest and least desirable two-decker in the Navy List." Moreover, she is 250 men short of a full crew, so Hornblower must enlist and train "poachers, bigamists, sheepstealers," and other landlubbers. By the time the Sutherland reaches the blockaded Catalonian coast of Spain, the crew is capable of staging five astonishing solo raids against the French. But the grisly prospect of defeat and capture looms for both captain and crew as the Sutherland single-handedly takes on four French ships.

Flying colours: Forced to surrender his ship, the Sutherland, after a long and bloody battle, Captain Horatio Hornblower now bides his time as a prisoner in a French fortress. Within days he and his first lieutenant, Bush, who was crippled in the last fight, are to be taken to Paris to be tried on trumped-up charges of violating the laws of war, and most probably executed as part of Napoleon's attempt to rally the warweary empire behind him. Even if Hornblower escapes this fate and somehow finds his way back to England, he will face court-martial for his surrender of a British ship. As fears for his life and his reputation compete in his mind with worries about his pregnant wife and his possibly widowed lover, the indomitable captain impatiently awaits the chance to make his next move.
