Before taking the Renown back to Jamaica for their court martial on charges of mutiny, Hornblower, Kennedy, and Bush convince an insecure and indecisive Lt. Buckland, now acting captain, that it would be appropriate to launch a surprise attack on the Spanish fortress at Santo Domingo. Matters are complicated when the inept Buckland incurs the enmity of the local rebels, who now regard them as enemies too. Captain Sawyer's increasing paranoia, deserting seamen, Buckland's growing jealousy of Hornblower, and the duplicity of the Spaniards all complicate the already perilous situation.
