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....

The year: 1943. Now there was to be no more retreat for Britain and her Allies. At last the war was to be carried into enemy territory. And from captured bases and makeshift harbours in North Africa, the Royal Navy's Special Force was to be the probe and the spearhead of the advance. To this unorthodox war came the corvette H. M. S. Thistle and her commanding officer, John Crispin.

It was in 1943. On the Black Sea, the Russians were fighting a desperate battle to regain control. But the Russians’ one real weakness was on the water: whatever they did, the Germans did it better, and the daring hit-and-run tactics of the E-boats plagued them. At last the British agreed to send them a small flotilla of motor torpedo boats under the command of John Devane. Devane had been in the Navy since the outbreak of war.

As captain of the crack Tribal Class destroyer HMS Hakka, Commander Graham Martineau must once again call from the ordinary seamen the ultimate in courage, and prepare to defend to the death vital convoys to Russia. No man and no ship is immortal.

As the Second World War progresses, the destruction of Allied shipping mounts. Fighter pilot Tim Rowan is posted to an escort carrier to help guard the precious convoys. His adventures take him first to the Arctic and then the Indian Ocean.

February 1943. As the balance of the war slowly shifts in Britain's favour, Lieutenant-Commander Steven Marshall brings his battle-scarred submarine into home port. Captain and crew are exhausted after 14 months' continuous service, but for most there can be no thought of leave. If the enemy collapse in North Africa is to be exploited, every experienced man will be needed. Marshall must return to the Mediterranean, but this time to a very different kind of war.

The human torpedo, or chariot, is the ultimate weapon in a war, and only men of extreme courage or recklessness volunteer for the special operations missions requiring its use. Reeman has also written 22 novels under the pseudonym Alexander Kent.

Adriatic, 1940s... Curtis was the pro. He could steer a sub through a saloon and no one would notice. Duncan was the grumbler, more at home in the Aussie Outback than twenty fathoms under the Adriatic. Jervis was the spit-and-polish man, who knew the correct way to die. And George, the Cockney, was the toughest of them all. Four men in the Royal Navy’s smallest sub, preparing the way for history’s largest invasion.

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. Against the mighty backdrop of World War II they performed their small but deadly operations - living often beyond hope, sometimes beyond mercy. This is the dramatic story of a handful of such people. The Volunteers.

HMS Wagtail is a river gunboat, a ship seemingly at the end of her unusual life, lying in a Hong Kong dockyard awaiting her last summons to the breakers' yard. Commander Justin Rolfe is also seemingly at the end of his useful naval life, an embittered man, brooding and angry from a court-martial verdict. Then the offshore island of Santu is threatened with invasion from the Chinese mainland.

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. For Captain Mark Gunnar - driven by the memory of his torture at the hands of the Viet Cong guerrillas - the new command is a chance to even the score against a ruthless, unrelenting enemy. But Payenhau is very different from his expectations....

The dramatic sequel to Badge of Glory, China 1900. When the Boxer Rebellion erupts into bloody war. The Royal Marines, true to their motto, are the first to land - and the last to leave. Again, a Blackwood is in command.

The crack German cruiser Prinz Luitpold had always been lucky in battle. To the beleaguered army on the Baltic coast she was their one remaining symbol of hope. But it is the summer of 1944, and on every front the war is going badly for Germany. When the order comes to leave the Baltic to attack and destroy enemy shipping in the Atlantic, Kapitan zur See Dieter Hechler knows that once out in this vast killing ground it will only be a matter of time before the hunter becomes the hunted.

Twenty-five years ago HMS Terrapin was part of a crack hunter/killer group in the Battle of the Atlantic. Now she is working out her last commission in the Gulf of Thailand. 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. And under his stubborn leadership, Standish and the crew discover a long-forgotten unity of purpose.

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.
