Then suddenly the mammoths were fleeing, running from the smoke and flames and smashing into those behind them in their terror. Those went backward too, the giants and wildlings behind them scrambling to get out of their way. In half a heartbeat the whole center was collapsing. The horsemen on the flanks saw themselves being abandoned and decided to fall back as well, not one so much as blooded. Even the chariots rumbled off, having done nothing but look fearsome and make a lot of noise. When they break, they break hard, Jon Snow thought as he watched them reel away. The drums had all gone silent. How do you like that music, Mance? How do you like the taste of the Dornishman's wife? "Do we have anyone hurt?" he asked.

"The bloody buggers got my leg." Spare Boot plucked the arrow out and waved it above his head. "The wooden one!"

A ragged cheer went up. Zei grabbed Owen by the hands, spun him around in a circle, and gave him a long wet kiss right there for all to see. She tried to kiss Jon too, but he held her by the shoulder and pushed her gently but firmly away. "No," he said. I am done with kissing. Suddenly he was too weary to stand, and his leg was agony from knee to groin. He fumbled for his crutch. "Pyp, help me to the cage. Grenn, you have the Wall."

"Me?" said Grenn. "Him?" said Pyp. It was hard to tell which of them was more horrified. "But," Grenn stammered, "b-but what do I do if the wildlings attack again?"

"Stop them," Jon told him.

As they rode down in the cage, Pyp took off his helm and wiped his brow. "Frozen sweat. Is there anything as disgusting as frozen sweat?" He laughed. "Gods, I don't think I have ever been so hungry. I could eat an aurochs whole, I swear it. Do you think Hobb will cook up Grenn for us?" When he saw Jon's face, his smile died. "What's wrong? Is it your leg?"

"My leg," Jon agreed. Even the words were an effort.

"Not the battle, though? We won the battle."

"Ask me when I've seen the gate," Jon said grimly. I want a fire, a hot meal, a warm bed, and something to make my leg stop hurting, he told himself. But first he had to check the tunnel and find what had become of Donal Noye.

After the battle with the Therms it had taken them almost a day to clear the ice and broken beams away from the inner gate. Spotted Pate and Kegs and some of the other builders had argued heatedly that they ought just leave the debris there, another obstacle for Mance. That would have meant abandoning the defense of the tunnel, though, and Noye was having none of it. With men in the murder holes and archers and spears behind each inner grate, a few determined brothers could hold off a hundred times as many wildlings and clog the way with corpses. He did not mean to give Mance Rayder free passage through the ice. So with pick and spade and ropes, they had moved the broken steps aside and dug back down to the gate.

Jon waited by the cold iron bars while Pyp went to Maester Aemon for the spare key. Surprisingly, the maester himself returned with him, and Clydas with a lantern. "Come see me when we are done," the old man told Jon while Pyp was fumbling with the chains. "I need to change your dressing and apply a fresh poultice, and you will want some more drearnwine for the pain."

Jon nodded weakly. The door swung open. Pyp led them in, followed by Clydas and the lantern. It was all Jon could do to keep up with Maester Aemon. The ice pressed close around them, and he could feel the cold seeping into his bones, the weight of the Wall above his head. it felt like walking down the gullet of an ice dragon. The tunnel took a twist, and then another. Pyp unlocked a second iron gate. They walked farther, turned again, and saw light ahead, faint and pale through the ice. That's bad, Jon knew at once. That's very bad.

Then Pyp said, "There's blood on the floor."

The last twenty feet of the tunnel was where they'd fought and died. The outer door of studded oak had been hacked and broken and finally torn off its hinges, and one of the giants had crawled in through the splinters. The lantern bathed the grisly scene in a sullen reddish light. Pyp turned aside to retch, and Jon found himself envying Maester Aemon his blindness.

Noye and his men had been waiting within, behind a gate of heavy iron bars like the two Pyp had just unlocked. The two crossbows had gotten off a dozen quarrels as the giant struggled toward them. Then the spearmen must have come to the fore, stabbing through the bars. Still the giant found the strength to reach through, twist the head off Spotted Pate, seize the iron gate, and wrench the bars apart. Links of broken chain lay strewn across the floor. One giant. All this was the work of one giant.

"Are they all dead?" Maester Aemon asked softly.

"Yes. Donal was the last." Noye's sword was sunk deep in the giant's throat, halfway to the hilt. The armorer had always seemed such a big man to Jon, but locked in the giant's massive arms he looked almost like a child. "The giant crushed his spine. I don't know who died first." He took the lantern and moved forward for a better look. "Mag." I am the last of the giants. He could feel the sadness there, but he had no time for sadness. "It was Mag the Mighty. The king of the giants."

He needed sun then. It was too cold and dark inside the tunnel, and the stench of blood and death was suffocating. Jon gave the lantern back to Clydas, squeezed around the bodies and through the twisted bars, and walked toward the daylight to see what lay beyond the splintered door.

The huge carcass of a dead mammoth partially blocked the way. One of the beast's tusks snagged his cloak and tore it as he edged past. Three more giants lay outside, half buried beneath stone and slush and hardened pitch. He could see where the fire had melted the Wall, where great sheets of ice had come sloughing off in the heat to shatter on the blackened ground. He looked up at where they'd come from. When you stand here it seems immense, as if it were about to crush you.

Jon went back inside to where the others waited. "We need to repair the outer gate as best we can and then block up this section of the tunnel. Rubble, chunks of ice, anything. All the way to the second gate, if we can. Ser Wynton will need to take command, he's the last knight left, but he needs to move now, the giants will be back before we know it. We have to tell him — "

"Tell him what you will," said Maester Aemon, gently. "He will smile, nod, and forget. Thirty years ago Ser Wynton Stout came within a dozen votes of being Lord Commander. He would have made a fine one. Ten years ago he would still have been capable. No longer. You know that as well as Donal did, Jon."

It was true. "You give the order, then," Jon told the maester. "You have been on the Wall your whole life, the men will follow you. We have to close the gate."

"I am a maester chained and sworn. My order serves, Jon. We give counsel, not commands."

"Someone must — "

"You. You must lead." "No." "Yes, Jon. It need not be for long. Only until such time as the garrison returns. Donal chose you, and Qhorin Halfhand before him. Lord Commander Mormont made you his steward. You are a son of Winterfell, a nephew of Benjen Stark. It must be you or no one. The Wall is yours, Jon Snow."
