“Ansiau’s in trouble,” remarked the leader of another conroy of horsemen, watching the growing turmoil. “An ambush. We’ll hook round behind it and catch them between him and us. Teach ’em a lesson; they won’t try it again.”

As he began to lead his men round in a wide sweep, there came a thud in the air and a sudden terrible shrieking behind him: a great dart from nowhere, striking a man in the thigh, driving through, pinning the screaming man to his dead horse. Not from the ambush. From somewhere else. The leader stood up in his stirrups, searching round the featureless landscape for something to show him where to charge. Trees, fields of standing wheat. Hedges everywhere. As he hesitated, a crossbow-bolt, shot from a steady rest by a man under a hedge a hundred and fifty yards off, caught him full in the face. The marksman, a poacher from Ditton-in-the-Fen, made no attempt to leap to his feet and run. In ten heartbeats he was twenty yards away, crawling like an eel in a half-filled ditch. The waxed and twisted gut of his crossbow, he had already discovered, had took little harm from the wet. As the horsemen hesitated, spurred in the end toward the place where they thought the shot might have come from, the sights of another twist-shooter trained round.

Slowly, without horns or trumpets, like a cogwheel tightening a rope, twenty separate skirmishes began to grow into battle.

From his vantage point on the ridge, Shef saw the Frankish main force still riding forward: but slowly, at no more than a walk, with many checks. They did not like to advance without their flanks secured. And on the flanks, for long moments, there was scarcely anything to be seen. Then horsemen would appear, spurring round a copse, or charging a burned-out village in extended line. What they were charging or spurring after was usually invisible. Then, as Shef strained his one eye in the blurring rain, he caught a flash of movement far out to one side: a pair of horses side by side at full gallop, one of the twist-shooters bouncing behind, its team drumming their ponies with their heels in a long trail behind. Oswi and “Dead Level” pulling out at one end of a hamlet as the Franks poured in the other, the flanking movement that was meant to cut him off delayed and confused by shots from other directions. The catapult disappeared behind a dip in the ground. In seconds it would be unlimbered again, once more menacing a wide arc anywhere within its half-mile range.
