Charles Hayden sets off aboard the ill-fated HMS Themis with orders to destroy a French frigate and to gather intelligence from a royalist spy. On discovering French plans for an imminent invasion of England, Hayden must return to Portsmouth to give warning before it's too late. But the enemy has been lying in wait for him, and so begins a dangerous chase out into the Atlantic and into the clutches of a powerful French squadron…

Reunited with his crew aboard the frigate HMS Themis, Captain Charles Hayden is ordered by the Admiralty to the West Indies to carry war to the French among their own islands. Before he makes port in Barbados, the Themis intercepts a single boat adrift in the middle of the ocean - its sole occupants, two young Spanish noblemen. But not is all as it seems with Hayden’s unexpected guests.

As the streets of Paris are overrun with revolutionary fervour, England prepares for the inevitable war with France. Lieutenant Charles Hayden is a man of undeniable ability. The son of an Englishman, his allegiance to the English Crown is beyond dispute. But, with a French mother, and without any influence in the Admiralty, he is seemingly overlooked for his first commission as Master and Commander. Instead, he is posted to an ageing frigate, the Themis.

Newly promoted to captain, William Brewer is tasked to serve and defend British interests in the waters off Brazil. But who defines what constitutes Britain’s Interests? Portugal’s former colony is declaring independence, and an independent Brazil might better serve Britain’s economic development. King George, however, chooses to support Portugal’s monarch and his efforts to retain the colony. At the very least, Portugal’s king wants to retrieve the royal treasury that was sent to Brazil for safekeeping during the Napoleonic wars.

It is said that a man is grown by his past, and so it was with William Brewer. Before he took command of HMS Defiant in a hurricane and before he hunted pirates in HMS Revenge, Brewer endured a crucible of fire that molded him into the legend he became. Fresh from the tutelage of Napoleon Bonaparte on St. Helena, Brewer signs on for a cruise under Captain Bush in HMS Lydia to the Mediterranean to battle the Barbary Pirates.

The Mediterranean, 1793. Despite Britain's successes, the outcome of the sea war is still in the balance. As soon as his ship's refit is completed, Captain Richard Bolitho is ordered to join the blockade off the French coast.

Admiral Horatio Hornblower has given Commander William Brewer captaincy of the captured pirate sloop El Dorado. Now under sail as the HMS Revenge, its new name suits Brewer's frame of mind perfectly. He lost many of his best men in the engagement that seized the ship, and his new orders are to hunt down the pirates who have been ravaging the trade routes of the Caribbean sea. But Brewer will face more than one challenge before he can confront the pirate known as El Diabolito.

New York, 1777. As the American Revolution rages on the mainland, the British Navy prepares for action at sea. Against a growing fleet of American and French privateers, the Navy must maintain its blockade of Washington's vital military supplies. Caught up in the turmoil, junior officer Richard Bolitho finds himself having to make momentous decisions in the heat of battle, decisions that will affect the lives of many men, and perhaps the outcome of history.

The gathering might of revolutionary France prepares to engulf Europe in another bloody war. As in the past, Britain will stand or fall by the fighting power of her fleet. For Richard Bolitho, the renewal of hostilities means a fresh command.

Vice-Admiral Sir Richard Bolitho finds himself the new master of the Argonaute, a French flagship taken in battle. With the Peace of Amiens in ruins, he must leave the safety of Falmouth. What lies ahead is the grim reality of war at close quarters - where Bolitho will be called upon to anticipate the overall intention of the French fleet. But the battle has also become a personal vendetta between himself and the French admiral who formerly sailed the Argonaute.

Plymouth, July 1801: Richard Bolitho's small squadron, still repairing battle scars earned in heavy action at Copenhagen, has been months away from the sea. But the Admiralty needs Bolitho. After eight years of war with France, Britain must make a gesture that will show her strength and determination - and one which will dramatically weaken the French cause. The Admiralty wants to attack, so Rear-Admiral Bolitho must follow his flag's tradition of victory.

Despatched on a secret mission, the company of a 28-gun frigate must face the hazards of conspiracy, treason, and piracy. And recently appointed third lieutentant Richard Bolitho must learn to accept his new responsibilities as a King's officer.

1811. The Adriatic, the 'French Lake', is now the most valuable territory Napoleon Bonaparte possesses. Captain Sir Thomas Kydd finds his glorious return to England cut short when the Admiralty summons him to lead a squadron of frigates into these waters to cause havoc and distress to the enemy. Kydd is dubbed 'The Sea Devil' by Bonaparte who personally appoints one of his favourites, Dubourdieu, along with a fleet that greatly outweighs the British, to rid him of this menace.

Malta 1941. To most people H.M.S. Saracen is just an ugly, obsolete ship with an equally ugly recent history: her last commander is due for court-martial after shelling the troops he was sent to protect. But to Captain Richard Chesnaye she brings back memories - memories of the First World War when he and the old monitor went through the Gallipoli campaign together. It seems that captain and ship are both past their best. But as the war enters a new phase Chesnaye senses the possibility of a fresh, significant role - for him and the Saracen.

January 1782, Portsmouth. His Britannic Majesty's frigate Phalarope is ordered to the assistance of the hard-pressed squadrons in the Caribbean. Aboard is her new commander - Richard Bolitho. To all appearances the Phalarope is everything a young captain could wish for. But beneath the surface she is a deeply unhappy ship - her wardroom torn by petty greed and ambition, her deckhands driven to near mutiny by senseless ill treatment.
