Then, for no apparent reason, the atmosphere became tense again. A battle cry went up from somewhere. All the horses suddenly turned skittish. A cheer began, and was drowned, almost instantly, by the thunder of hooves. The battle was on. William smelled the sour, sweaty odor of fear.

He looked around, trying desperately to figure out what was happening, but all was confusion, and being on foot he could see only his immediate surroundings. The earls on the right seemed to have started the battle by charging the enemy. Presumably the forces opposite them, Earl Robert’s army of disinherited nobles, were responding in like manner, charging in formation. Almost immediately, a cry went up from the left, and William turned to see that the mounted men among the Breton mercenaries were spurring their horses forward. At that, a bloodcurdling cacophony arose from the corresponding section of the enemy army-the Welsh mob, presumably. He could not see who had the advantage.

He had lost sight of Richard.

Dozens of arrows rose like a flock of birds from behind the enemy lines and began to fall all around. William held his shield over his head. He loathed arrows-they killed at random.

King Stephen roared a war cry and charged. William drew his sword and ran forward, calling his men to follow. But the horsemen on his left and right had fanned out as they charged forward, and they came between him and the enemy.

On his right, there was a deafening clash of iron on iron, and the air filled with a metallic smell he knew well. The earls and the disinherited had joined battle. All he could see was men and horses colliding, wheeling, charging and falling. The neighing of the beasts was indistinguishable from the men’s battle cries, and somewhere in that noise William could already hear the bone-chilling, dreadful screams of wounded men in agony. He hoped Richard was one of those screaming.

William looked left and was horrified to see that the Bretons were falling back before the clubs and axes of the wild Welsh tribesmen. The Welsh were berserk, yelling and screaming and trampling one another in their eagerness to get at the enemy. Perhaps they were greedy to loot the rich city. The Bretons, with nothing more than the prospect of another week’s pay to spur them on, were fighting defensively and giving ground. William was disgusted.

He was frustrated that he had not yet struck a single blow. He was surrounded by his knights, and ahead of him were the horses of the earls and the Bretons. He pushed forward, slightly ahead and to one side of the king. There was combat all around: fallen horses, men fighting hand to hand with the ferocity of cats, the deafening ring of swords, and the sickly smell of blood; but William and King Stephen were, for the moment, stuck in a dead zone.

Philip could see everything, but he understood nothing. He had no idea what was going on. All was confusion: flashing blades, charging horses, banners flying and falling, and the sounds of battle, carried on the wind, muted by distance. It was maddeningly frustrating. Some men fell and died, others overcame and fought on, but he could not tell who was winning and who losing.

A cathedral priest standing nearby in a fur coat looked at Philip and said: “What’s going on?”

Philip shook his head and said: “I can’t tell.”

But even as he spoke he discerned a movement. To the left of the battlefield, some men were running away down the hill toward the canal. They were drab-dressed mercenaries, and as far as Philip could tell, it was the king’s men who were fleeing and the painted tribesmen of the attacking army who were in pursuit. The victorious whooping of the Welsh could be heard from here. Philip’s hopes lifted: the rebels were winning already!

Then there was a sea change on the other side. To the right, where the mounted men were engaged, the king’s army seemed to be falling back. The movement was at first slight, then steady, then rapid; and even as Philip watched, the retreat turned into a rout, and scores of the king’s men turned their horses and began to flee from the battlefield.

Philip was elated: this must be God’s will!

Could it really be over so quickly? The rebels were advancing on both flanks, but the center was still holding steady. The men around King Stephen were fighting more fiercely than those to either side. Would they be able to stem the flow? Perhaps Stephen and Robert of Gloucester would fight it out personally: single combat between two leaders could sometimes settle the issue regardless of what was happening elsewhere on the field. It was not yet over.

The tide turned with horrifying speed. At one moment the two armies were even, both sides fighting fiercely; and at the next, the king’s men were falling back fast. William was deeply disheartened. On his left, the Breton mercenaries were running away down the hill and being chased into the canal by the Welsh; and on his right, the earls with their war-horses and banners were turning from the fight and trying to escape back toward Lincoln. Only the middle was holding: King Stephen was in the thick of it, laying about him with his massive sword, and the Shiring men were fighting like pack-wolves all around him. But the situation was unstable. If the flanks continued to retreat the king would end up surrounded. William wanted Stephen to fall back. But the king was more brave than wise, and he fought on.

William felt the entire battle take a lurch to the left. Looking around, he saw the Flemish mercenaries coming from behind and falling on the Welsh, who were forced to stop chasing the Bretons down the hill and turn to defend themselves. For a moment there was a melee. Then Ranulf of Chester’s men, in the middle of the enemy front line, attacked the Flemish, who now found themselves squeezed between the men from Chester and the Welsh.

Seeing the rally, King Stephen urged his men to press forward. William thought Ranulf might have made a mistake. If the king’s forces could close with Ranulf’s men now, Ranulf would be the one who was squeezed on two sides.

One of William’s knights fell in front of him and suddenly he was in the midst of the fighting.

A beefy northerner with blood on his sword lunged at him. William parried the thrust easily: he was fresh and his antagonist was already tired. William thrust at the man’s face, missed, and parried another jab. He raised his sword high, deliberately opening himself to a stab; then, when the other man predictably stepped forward with another thrust, William dodged it and brought his sword down, two-handed, on the other man’s shoulder. The blow split the man’s armor and broke his collarbone, and he fell.

William enjoyed a moment of elation. His fear had gone. He roared: “Come on, you dogs!”

Two more men took the place of the fallen knight and attacked William simultaneously. He held them off but he was forced to give ground.

There was a surge on his right, and one of his opponents had to turn aside to defend himself against a red-faced man armed with a cleaver, who looked like a crazed butcher. That left only one for William to deal with. He grinned savagely and pressed forward. His opponent panicked and slashed wildly at William’s head. William ducked and stabbed the man in the thigh, just below the fringe of his short mail jacket. The leg buckled and the man fell.

Once again William had no one to fight. He stood still, breathing hard. For a moment he had thought the king’s army was going to be routed, but they had rallied, and now neither side appeared to have the advantage. He looked to his right, wondering what had caused the surge that had distracted one of his antagonists. To his astonishment he saw that the citizens of Lincoln were giving the enemy a hard fight. Perhaps it was because they were defending their own homes. But who had rallied them, after the earls on that flank had fled? His question was answered: to his dismay he saw Richard of Kingsbridge on his war-horse, urging the townsmen on. William’s heart sank. If the king saw Richard being brave it could undo all William’s work. William looked over at Stephen. At that moment the king caught Richard’s eye and waved encouragement. William let out a resentful curse.
