June, 1808 - and off the Coast of Nicaragua Captain Horatio Hornblower has his hands full ...

Now in command of HMS Lydia, a thirty-six-gun frigate, Hornblower has instructions to form an alliance against the Spanish colonies with a mad and messianic revolutionary, El Supremo; 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. And as if that wasn't hard enough, Hornblower must also contend with the charms of an unwanted passenger: Lady Barbara Wellesley ... This is the fifth of eleven books chronicling the adventures of C. S. Forester's inimitable nautical hero, Horatio Hornblower.
