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....

In 1941, when she was turned into an armed merchant cruiser, the SS Benbecula was already old. Yet even she was needed to protect the vital Atlantic sea lanes. Commander Lindsay, her new captain, had to work desperately to mould the ship’s company - raw recruits and old-timers - into a fighting force. And better than anyone, Lindsay knew this could be his last command, his last chance.

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.

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.

Western Ocean, 1942... From the bridge of HMS Gladiator, Lieutenant-Commander David Howard’s orders were chillingly clear. There could be no mercy. To the men who fought to protect the vital, threatened Merchant Navy convoys in the Western Approaches, the Battle of the Atlantic was a full-scale war. A relentless, savage war against an ever-present enemy and a violent sea - in an arena known only to its embittered survivors as the killing ground. HMS Gladiator was part of that war.

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....

In November 1941, Lt Ralph Trewin, DSC arrives at Singapore as second-in-command of HMS Porcupine. To the shell-shocked Trewin, the gun boat and her five elderly consorts symbolise the ignorance and blind optimism he finds in Singapore.

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.

It was an age of empire, an age of contrast, and an age of dramatic change - and one which would determine the destinies of nations as well as of men. Captain Philip Blackwood of the Royal Marines rejoins his ship, HMS Audacious, in August of 1850, anxious to get back into action. "Per Mare - Per Terram" is the marines' motto. In the torturous heat of Africa, where they are sent to stamp out the remaining strongholds of slavery, and later, in the bitter war of the Crimea, Philip Blackwood and his men learn to obey it without question.

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.

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.

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.

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.

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.

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.
