To Lieutenant-Commander Standish, the frigate seems to mark the end of his hopes of a career in the navy. Then a new captain arrives, a man driven by an old-fashioned, almost obsessive patriotism.

They were the men and women of the Royal Navy's Special Operations units. Carrying out lightning raids on hostile coasts, they became a navy within a navy - each handpicked for their individual skills, and all of them courageous.

This is the dramatic story of a handful of such people. The Volunteers.

The old submarine-chaser USS Hibiscus, re-fitting in a Hong Kong dockyard before being handed over to the Nationalist Chinese, is suddenly ordered to the desolate island group of Payenhau.

Then the offshore island of Santu is threatened with invasion from the Chinese mainland.

From the author of The First to Land, a novel set during World War II. They called them the Scrapyard Flotilla. After a quarter of a century of service, the eight destroyers had seen all kinds of action. Now they were to be used in raids to open the way for the invasion of Occupied Europe.

The Mediterranean, 1943... The HMS Rob Roy. A tiny machine, just 230 feet from stem to stern. In peacetime she would have trawled for cod. Now her catch is deadlier by far. Lieutenant-Commander Ian Ransome is a veteran of the treacherous front line of naval combat. Under sealed orders in the battle-tossed waters of the Mediterranean, he and his jack-tired crew face one final test of their courage....

It takes a special sort of courage to serve in midget submarines, and Lieutenant David Seaton, commanding officer of XE16, needs no reminding of the perils involved. The little X-craft with their four-man crews have been used against heavy enemy surface units and important harbour installations. But in 1944, with the Allies poised for an invasion through France, a new and more hazardous role is given to Seaton's flotilla.

And once in Asian waters, he and his submarine find themselves involved in a hidden, undeclared conflict beneath the sea.

HMS Royston, Coastal Forces Depot Ship, is mother ship to a battered, war-worn bunch of MTBs and MGBs. New on board is Sub-Lieutenant Royce: commissioned for three months, sea experience three months in an Asdic trawler, and aged 20. His commanding officer is Lieutenant Harston, aged 23.

His predecessor has been killed in action 48 hours earlier and is now hardly remembered. The crew are all young - some very young - but all old before their time....

There will be days when you wonder at and question some of the risks you had to take, the sacrifices you were forced to offer in the face of death. In Kiel Harbour, 1945, the war in Europe is at an end. But for Lieutenant Vere Marriott and the men of MGB 801, moored amid a nightmare of devastation, it is an uneasy, unsettled peace. New assignments ashore and afloat mean fresh tensions and conflicting emotions. For some, glory now takes second place to profit.

Indo-China 1941, and cruising somewhere off Saigon is the world’s largest, most dangerous submarine, the French Soufriere. The British navy must capture and use her in the defence of Singapore before she is used against them. For Commander Robert Ainslie it is the supreme challenge of his career.

To Brooke, attack by Japan seems inevitable.
