It was nowhere near enough to besiege the castle, of course. However, they had devised a plan for taking the castle without a siege. The problem was that the attacking army would be seen by lookouts, and the castle would be closed up long before they arrived. The answer was to find some way to keep the castle open for the time it took the army to get there from its place of concealment in the woods.

It had been Mother who solved the problem, of course.

“We need a diversion,” she had said, scratching a boil on her chin. “Something to panic them, so that they don’t notice the army until it’s too late. Like a fire.”

Father said: “If a stranger walks in and starts a fire, that will alert them anyway.”

“It would have to be done on the sly,” William said.

“Of course it would,” said Mother impatiently. “You’ll have to do it while they’re at mass.”

“Me?” William had said.

He had been put in charge of the advance party.

The morning sky lightened with painful slowness. William was nervously impatient. During the night, he and Mother and Father had added refinements to the basic idea, but still there was a great deal that could go wrong: the advance party might not get into the castle for some reason, or they might be viewed with suspicion and be unable to act surreptitiously, or they might be caught before they could achieve anything. Even if the plan worked, there would be a battle, William’s first real fight. Men would be wounded and killed, and William might be one of the unlucky ones. His bowels tightened with fear. Aliena would be there, and she would know if he were vanquished. On the other hand, she would be there to see it if he triumphed. He pictured himself bursting into her bedroom with a bloody sword in his hand. Then she would wish she had not laughed at him.

From the castle came the sound of the bell for morning mass.

William nodded, and two men detached themselves from the group and began to walk across the fields toward the castle. They were Raymond and Ranulf, two hard-faced, hard-muscled men some years older than William. William had picked them himself: his father had given him complete control. Father himself would lead the main assault.

William watched Raymond and Ranulf walk briskly across the frozen fields. Before they reached the castle, he looked at Walter, then kicked his horse, and he and Walter set off across the fields at a trot. The sentries on the battlements would see two separate pairs of people, one on foot and one on horseback, approaching the castle first thing in the morning: it looked perfectly innocent.

William’s timing was good. He and Walter passed Raymond and Ranulf about a hundred yards from the castle. At the bridge they dismounted. William’s heart was in his mouth. If he messed up this part, the whole attack would be ruined.

There were two sentries at the gate. William had a nightmarish suspicion that there would be an ambush, and a dozen men-at-arms would spring out of concealment and hack him to pieces. The sentries looked alert but not anxious. They were not wearing armor. William and Walter had chain mail under their cloaks.

William’s guts seemed to have turned to water. He could not swallow. One of the sentries recognized him. “Hello, Lord William,” he said jovially. “Come courting again, have you?”

William said “Oh, my God,” in a weak voice, then plunged a dagger into the sentry’s belly, jabbing it up under the rib cage to the heart.

The man gasped, sagged, and opened his mouth as if to scream. A noise could spoil everything. Panicking, not knowing what to do, William pulled out the dagger and stuck it into the man’s open mouth, shoving the blade into his throat to shut him up. Instead of a scream, blood flowed out of his mouth. The man’s eyes closed. William pulled the dagger out as the man fell to the ground.

William’s horse had sidestepped away, frightened by the sudden movements. William caught its bridle, then looked at Walter, who had taken the other sentry. Walter had knifed his man more efficiently, slitting his throat, so that he died in silence. I must remember that, William thought, next time I have to silence a man. Then he thought: I’ve done it! I’ve killed a man!

He realized he was no longer scared.

He handed his reins to Walter and ran up the spiral staircase to the gatehouse tower. On the upper level was a winding room for pulling up the drawbridge. With his sword, William hacked at the thick hawser. Two blows were sufficient to sever it. He dropped the loose end out of the window. It fell on the bank and slid softly into the moat, hardly making a splash. Now the drawbridge could not be raised against Father’s attacking force. This was one of the refinements they had thought of last night.

Raymond and Ranulf arrived at the gatehouse just as William reached the foot of the stairs. Their first job was to wreck the huge ironbound oak gates which closed the arch leading from the bridge into the compound. They each took out a wooden hammer and a chisel and began to chip out the mortar surrounding the mighty iron hinges. The striking of hammer on chisel made a dull thud which sounded terribly loud to William.

William dragged the two dead sentries into the guardroom quickly. With everyone at mass, there was a strong chance the bodies would not be seen until it was too late.

He took his reins from Walter and the two of them walked out from under the arch and headed across the compound toward the stable. William forced his legs to move at a normal, unhurried pace, and glanced surreptitiously up at the sentries on the watchtowers. Had one of them seen the drawbridge rope fall into the moat? Were they wondering about the sound of hammering? Some of them were looking at William and Walter, but they did not seem agitated, and the hammering, which was already fading in William’s ears, must have been inaudible from the tops of the towers. William felt relieved. The plan was working.

They reached the stables and went inside. They both draped their horses’ reins loosely over a bar, so the beasts could escape. Then William took out his flint and scraped a spark, setting fire to the straw on the floor. It was soiled and damp in patches, but nevertheless it began to smolder. He lit three more small fires, and Walter did the same. They stood watching for a moment. The horses caught a whiff of smoke, and moved nervously in the stalls. William stayed a moment longer. The fire was under way, and so was the plan.

He and Walter left the stable and went out into the open compound. At the gateway, hidden under the arch, Raymond and Ranulf were still chipping away at the mortar around the hinges. William and Walter turned toward the kitchen, to give the impression that they might be going to get something to eat, which would be natural. There was no one else in the compound: everyone was at mass. Casually looking up at the battlements, William observed that the sentries were not looking into the castle, but out across the fields, as of course they were supposed to. Nevertheless William expected someone to emerge from one of the buildings at any moment and challenge them; and then they would have to kill him right here in the open, and if that were seen the game would be up.

They skirted the kitchen and headed for the bridge leading to the upper compound. They heard the muted sounds of the service as they passed the chapel. Earl Bartholomew was in there, all unsuspecting, William thought with a thrill; he had no idea that there was an army a mile away, four of the enemy were already inside his stronghold, and his stables were on fire. Aliena was in the chapel too, praying on her knees. Soon she’ll be on her knees to me, William thought, and the blood pounded in his head giddily.

They reached the bridge and started across. They had ensured that the first bridge remained passable, by cutting the drawbridge rope and disabling the gate, so that their army could get in. But the earl could still flee across the bridge and take refuge in the upper compound. William’s next task was to prevent this by raising the drawbridge to make the second bridge impassable. The earl would then be isolated and vulnerable in the lower compound.
