Ramage & the Renegades (Lord Ramage Novels, Number 12)

Nelson's crews are standing down and Ramage is on leave when he receives secret Admiralty orders to inspect the small island of Trinidade off the coast of Brazil. Reaching the island, Ramage and the crew of the Calypso fetch up in a battle to free several captive merchant ships—and a beautiful woman passenger—as they cross swords with blood-thirsty priates.
