"But they are nothing, Admiral Starr, just nothing at all. They are only the henchmen, the outriders, you might call them, of the Three Horsemen of the Apocalypse, cold, lack of sleep, exhaustion.

"Do you know what it's like up there, between Jan Mayen and Bear Island on a February night, Admiral Starr? Of course you don't. Do you know what it's like when there's sixty degrees of frost in the Arctic, and it still doesn't freeze? Do you know what it's like when the wind, twenty degrees below zero, comes screaming off the Polar and Greenland ice-caps and slices through the thickest clothing like a scalpel? When there's five hundred tons of ice on the deck, where five minutes' direct exposure means frostbite, where the bows crash down into a trough and the spray hits you as solid ice, where even a torch battery dies out in the intense cold? Do you, Admiral Starr, do you?" Brooks flung the words at him, hammered them at him.

"And do you know what it's like to go for days on end without sleep, for weeks with only two or three hours out of the twenty-four? Do you know the sensation, Admiral Starr? That fine-drawn feeling with every nerve in your body and cell in your brain stretched taut to breaking point, pushing you over the screaming edge of madness. Do you know it, Admiral Starr? It's the most exquisite agony in the world, and you'd sell your friends, your family, your hopes of immortality for the blessed privilege of closing your eyes and just letting go.

"And then there's the tiredness, Admiral Starr, the desperate weariness that never leaves you. Partly it's the debilitating effect of the cold, partly lack of sleep, partly the result of incessantly bad weather. You know yourself how exhausting it can be to brace yourself even for a few hours on a rolling, pitching deck: our boys have been doing it for months, gales are routine on the Arctic run. I can show you a dozen, two dozen old men, not one of them a day over twenty."
