       Prelude: Thursday

       0000–0600

      Commander Vincent Ryan, RN, Captain (Destroyers) and commanding officer of His Majesty’s latest S-class destroyer Sirdar, leaned his elbows comfortably on the coaming of his bridge, brought up his night-glasses and gazed out thoughtfully over the calm and silvered waters of the moonlit Aegean.

      He looked first of all due north, straight out over the huge and smoothly sculpted and whitely phosphorescent bow-wave thrown up by the knife-edged forefoot of his racing destroyer: four miles away, no more, framed in its backdrop of indigo sky and diamantine stars, lay the brooding mass of a darkly cliff-girt island: the island of Kheros, for months the remote and beleaguered outpost of two thousand British troops who had expected to die that night, and who would now not die.

      Ryan swung his glasses through 180° and nodded approvingly. This was what he liked to see. The four destroyers to the south were in such perfect line astern that the hull of the leading vessel, a gleaming bone in its teeth, completely obscured the hulls of the three ships behind. Ryan turned his binoculars to the east.

      It was odd, he thought inconsequentially, how unimpressive, even how disappointing, the aftermath of either natural or man-made disaster could be. Were it not for that dull red glow and wisping smoke that emanated from the upper part of the cliff and lent the scene a vaguely Dantean aura of primeval menace and foreboding, the precipitous far wall of the harbour looked as it might have done in the times of Homer. That great ledge of rock that looked from that distance so smooth and regular and somehow inevitable could have been carved out by the wind and weather of a hundred million years: it could equally well have been cut away fifty centuries ago by the masons of Ancient Greece seeking marble for the building of their Ionian temples: what was almost inconceivable, what almost passed rational comprehension, was the fact that ten minutes ago that ledge had not been there at all, that there had been in its place tens of thousands of tons of rock, the most impregnable German fortress in the Aegean and, above all, the two great guns of Navarone, now all buried for ever three hundred feet under the sea. With a slow shake of his head Commander Ryan lowered his binoculars and turned to look at the men responsible for achieving more in five minutes than nature could have done in five million years.

      Captain Mallory and Corporal Miller. That was all he knew of them, that and the fact that they had been sent on this mission by an old friend of his, a naval captain by the name of Jensen who, he had learnt only twenty-four hours previously – and that to his total astonishment – was the Head of Allied Intelligence in the Mediterranean. But that was all he knew of them and maybe he didn’t even know that. Maybe their names weren’t Mallory and Miller. Maybe they weren’t even a captain and a corporal. They didn’t look like any captain or corporal he’d ever seen. Come to that, they didn’t look like any soldiers he’d ever seen. Clad in salt-water-and blood-stained German uniforms, filthy, unshaven, quiet and watchful and remote, they belonged to no category of men he’d ever encountered: all he could be certain of as he gazed at the blurred and blood-shot sunken eyes, the gaunt and trenched and stubbled-grey faces of two men no longer young, was that he had never before seen human beings so far gone in total exhaustion.

      ‘Well, that seems to be about it,’ Ryan said. ‘The troops on Kheros waiting to be taken off, our flotilla going north to take them off and the guns of
