"Jon, it's still coming," said Owen the Oaf.

He could see that for himself. Inch by inch, yard by yard, the turtle crept closer, rolling, rumbling and rocking as it crossed the killing ground. Once the wildlings got it flush against the Wall, it would give them all the shelter they needed while their axes crashed through the hastily-repaired outer gates. Inside, under the ice, they would clear the loose rubble from the tunnel in a matter of hours, and then there would be nothing to stop them but two iron gates, a few half-frozen corpses, and whatever brothers Jon cared to throw in their path, to fight and die down in the dark.

To his left, the catapult made a thunk and filled the air with spinning stones. They plonked down on the turtle like hail, and caromed harmlessly aside. The wildling archers were still loosing arrows from behind their mantlets. One thudded into the face of a straw man, and Pyp said, "Four for Watt of Long Lake! We have a tie! " The next shaft whistled past his own ear, however. "Fie!" he shouted down. "I'm not in the tourney! "

"The hides won't burn," Jon said, as much to himself as to the others. Their only hope was to try and crush the turtle when it reached the Wall. For that, they needed boulders. No matter how stoutly built the turtle was, a huge chunk of rock crashing straight down on top of it from seven hundred feet was bound to do some damage. "Grenn, Owen, Kegs, it's time."

Alongside the warming shed a dozen stout oaken barrels were lined up in a row. They were full of crushed rock; the gravel that the black brothers customarily spread on the footpaths to give themselves better footing atop the Wall. Yesterday, after he'd seen the free folk covering the turtle with sheepskins, Jon told Grerm to pour water into the barrels, as much as they would take. The water would seep down through the crushed stone, and overnight the whole thing would freeze solid. It was the nearest thing to a boulder they were going to get.

"Why do we need to freeze it?" Grerm had asked him. "Why don't we just roll the barrels off the way they are?"

Jon answered, "If they crash against the Wall on the way down they'll burst, and loose gravel will spray everywhere. We don't want to rain pebbles on the whoresons."

He put his shoulder to the one barrel with Grenn, while Kegs and Owen were wrestling with another. Together they rocked it back and forth to break the grip of the ice that had formed around its bottom. "The bugger weighs a ton," said Grenn.

"Tip it over and roll it," Jon said. "Careful, if it rolls over your foot you'll end up like Spare Boot."

Once the barrel was on its side, Jon grabbed a torch and waved it above the surface of the Wall, back and forth, just enough to melt the ice a little. The thin film of water helped the barrel roll more easily. Too easily, in fact; they almost lost it. But finally, with four of them pooling their efforts, they rolled their boulder to the edge and stood it up again.

They had four of the big oak barrels lined up above the gate by the time Pyp shouted, "There's a turtle at our door!" Jon braced his injured leg and leaned out for a look. Hoardings, Marsh should have built hoardings. So many things they should have done. The wildlings were dragging the dead giants away from the gate. Horse and Mully were dropping rocks down on them, and Jon thought he saw one man go down, but the stones were too small to have any effect on the turtle itself. He wondered what the free folk would do about the dead mammoth in the path, but then he saw. The turtle was almost as wide as a longhall, so they simply pushed it over the carcass. His leg twitched, but Horse caught his arm and drew him back to safety. "You shouldn't lean out like that," the boy said.

"We should have built hoardings." Jon thought he could hear the crash of axes on wood, but that was probably just fear ringing in his ears. He looked to Grenn. "Do it."

Grerm got behind a barrel, put his shoulder against it, grunted, and began to push. Owen and Mully moved to help him. They shoved the barrel out a foot, and then another. And suddenly it was gone.

They heard the thump as it struck the Wall on the way down, and

then, much louder, the crash and crack of splintering wood, followed by shouts and screams. Satin whooped and Owen the Oaf danced in circles, while Pyp leaned out and called, "The turtle was stuffed full of rabbits! Look at them hop away!"

"Again," Jon barked, and Grerm and Kegs slammed their shoulders against the next barrel, and sent it tottering out into empty air.

By the time they were done, the front of Mance's turtle was a crushed and splintered ruin, and wildlings were spilling out the other end and scrambling for their camp. Satin scooped up his crossbow and sent a few quarrels after them as they ran, to see them off the faster. Grenn was grinning through his beard, Pyp was making japes, and none of them would die today.

On the morrow, though … Jon glanced toward the shed. Eight barrels of gravel remained where twelve had stood a few moments before. He realized how tired he was then, and how much his wound was hurting. I need to sleep. A few hours, at least. He could go to Maester Aemon for some dreamwine, that would help. "I am going down to the King's Tower," he told them. "Call me if Mance gets up to anything. Pyp, you have the Wall."

"Me?" said Pyp.

"Him?" said Grenn.

Smiling, he left them to it and rode down in the cage.

A cup of dreamwine did help, as it happened. No sooner had he stretched out on the narrow bed in his cell than sleep took him. His dreams were strange and formless, full of strange voices, shouts and cries, and the sound of a warhorn, blowing low and loud, a single deep booming note that lingered in the air.

When he awoke the sky was black outside the arrow slit that served him for a window, and four men he did not know were standing over him. One held a lantern. "Jon Snow," the tallest of them said brusquely, "pull on your boots and come with us."

His first groggy thought was that somehow the Wall had fallen whilst he slept, that Mance Rayder had sent more giants or another turtle and broken through the gate. But when he rubbed his eyes he saw that the strangers were all in black. They're men of the Night's Watch, Jon realized. "Come where? Who are you?"

The tall man gestured, and two of the others pulled Jon from the bed. With the lantern leading the way they marched him from his cell and up a half turn of stair, to the Old Bear's solar. He saw Maester Aemon standing by the fire, his hands folded around the head of a blackthorn cane. Septon Cellador was half drunk as usual, and Ser Wynton Stout was asleep in a window seat. The other brothers were strangers to him. All but one.

Immaculate in his fur-trimmed cloak and polished boots, Ser Alliser

Thorne turned to say, "Here's the tumcloak now, my lord. Ned Stark's bastard, of Winterfell."

"I'm no tumcloak, Thorne," Jon said coldly.

"We shall see." in the leather chair behind the table where the Old Bear wrote his letters sat a big, broad, jowly man Jon did not know. "Yes, we shall see," he said again. "You will not deny that you are Jon Snow, I hope? Stark's bastard?"

"Lord Snow, he likes to call himself." Ser Alliser was a spare, slim man, compact and sinewy, and just now his flinty eyes were dark with amusement.

"You're the one who named me Lord Snow," said Jon. Ser Alliser had been fond of naming the boys he trained, during his time as Castle Black's master-at-arms. The Old Bear had sent Thorne to Eastwatch-by-the-Sea. These others must be Eastwatch men. The bird reached Cotter Pyke and he's sent us help. "How many men have you brought?" he asked the man behind the table.

"It's me who'll ask the questions," the jowly man replied. "You've been charged with oathbreaking, cowardice, and desertion, Jon Snow. Do you deny that you abandoned your brothers to die on the Fist of the First Men and joined the wildling Mance Rayder, this self-styled King-beyondthe-Wall? "
