Far away across the battlefield, a gold-ringed head rose into view from a ruck of bodies—the king mounting. For a moment he seemed to be resisting, waving his sword forward. But someone else had hold of his bridle. A clot of riders began to walk, then canter from the fighting. As they did so, instantly men began to shred away from the fighting-lines, following their leader, at first casually. Then briskly, hastily. Realizing the movement behind them, others turned to look, to follow. The army of the Mark, still undestroyed, still unbeaten, many of its men still unafraid, began to stream to the rear. As it did so, the stones lashed out again. Men began to run.

The Wayman army was all on its feet now, all eyes turning expectantly toward the center. The moment, Shef thought. Sweep forward when both sides are fully engaged, take the machines before they can change target, board the ships, take Ivar in flank and rear …

“Give me some horsemen,” Alfred begged. “Burgred’s a fool, but he’s my sister’s husband. I have to save him. We’ll pension him off, send him to the Pope …”

Yes, thought Shef. And that will be one piece still on the board. And Ivar—even if we beat him Ivar will get away, by boat or horse, like he did last time. And that will be another. But we must have fewer pieces now. In the end, one piece alone. I want the mills to stop.

Blessedly, as he stepped forward, he felt some dreadful thing rising inside him, his mouth filling with the terrible cold saliva he had felt only once before, the time he had eaten carrion one hard winter. Grimly he clamped it down. All eyes, all eyes.

He turned, looked at the men rising from bracken and bush, eyes glaring, teeth showing with expectant rage. “Forward,” he shouted, lifting his halberd from the ground and sweeping it toward the river. “Men of the Way …”

The vomit shot from his mouth so fiercely it caught Alfred high up on his enameled shield. The king gaped, uncomprehending. Shef doubled up, acting no more; his halberd dropped. Again the great retchings took him, again and again, lifting him off his feet.

As he rolled on the fouled earth the Wayman army hesitated, staring in horror. Alfred raised an arm to shout for his horse, for his companions, then dropped it, turned back to stare at the figure writhing on the ground. Thorvin was running forward from his place in the rear. A buzz of doubt ran along the ranks: What’s the order? Are we going forward? Sigvarthsson is down? Who commands? Is it the Viking? Do we obey a pirate? An Englishman? The Wessex king?

As he sprawled in the grass, gasping for breath before the next upheaval, Shef heard the voice of Brand, looking down at him with stony disapproval.
