This, the first in the splendid series of Jack Aubrey novels, establishes the friendship between Captain Aubrey, Royal Navy, and Stephen Maturin, ship's surgeon and intelligence agent, against the thrilling backdrop of the Napoleonic wars. Details of life aboard a man-of-war in Nelson's navy are faultlessly rendered: the conversational idiom of the officers in the ward room and the men on the lower deck, the food, the floggings, the mysteries of the wind and the rigging, and the road of broadsides as the great ships close in battle.

In this, the final Horatio Hornblower adventure, C.S. Forester throws his hero into one of the most challenging missions yet. Upon discovering highly confidential papers dispatched by Bonaparte, Hornblower sets off to enlighten the Admiralty about his game-changing, new findings. Troubled after having been informed of Pierre-Charles Villeneuve's escape into Spain, they welcome Horatio's news and send him off on a high-priority assignment that they believe will lead to England's victory over Napoleon.

Horatio Hornblower sails South American waters and comes face to face with a mad revolutionary in a novel that ripples with risk and gripping adventure. Throughout his escapades, Forester's hero remains resourceful and courageous.
