While Hornblower replenishes his supplies, the 50-gun Spanish ship Natividad is sighted off the coast heading his way.

El Supremo demands that it be turned over to him so that he may have a navy. After hiding the captured Spanish officers to save them from being murdered by El Supremo, Hornblower, needing his erstwhile ally's cooperation, has no choice, but to accede.

Hornblower sets sail for England. On the long voyage, he and Lady Barbara become strongly attracted to each other. Nearing the end of their trip, she makes the first overt advances; Hornblower demurs, explaining that he is married. Also, as a man of humble social standing, he cannot afford to risk offending the influential Wellesley clan by dallying with her. After the rejection, the embarrassed Lady Barbara avoids him as best she can. Fortunately, an English convoy is sighted soon afterwards and she transfers to a more spacious ship. The book ends with their formal good-byes.
