All the same, Jon found himself hoping that Styr's fears proved well founded. If the gods are good, a patrol will chance by and put an end to this. "No wall can keep you safe," his father had told him once, as they walked the walls of Winterfell. "A wall is only as strong as the men who defend it." The wildlings might have a hundred and twenty men, but four defenders would be enough to see them off, with a few well-placed arrows and perhaps a pail of stones.
No defenders appeared, however; not four, not even one. The sun climbed the sky and the wildlings climbed the Wall. Jarl's four remained well ahead till noon, when they hit a pitch of bad ice. Jarl had looped his rope around a wind-carved pinnace and was using it to support his weight when the whole jagged thing suddenly crumbled and came crashing down, and him with it. Chunks of ice as big as a man's head bombarded the three below, but they clung to the handholds and the stakes held, and Jarl jerked to a sudden halt at the end of the rope.
By the time his team had recovered from that mischance, Grigg the Goat had almost drawn even with them. Errok's four remained well behind. The face where they were climbing looked smooth and unpitted, covered with a sheet of icemelt that glistened wetly where the sun brushed it. Grigg's section was darker to the eye, with more obvious features; long horizontal ledges where a block had been imperfectly positioned atop the block below, cracks and crevices, even chimneys along the vertical joins, where wind and water had eaten holes large enough for a man to hide in.
Jarl soon had his men edging upward again. His four and Grigg's moved almost side by side, with Errok's fifty feet below. Deerhom axes chopped
and hacked, sending showers of glittery shards cascading down onto the trees. Stone hammers pounded stakes deep into the ice to serve as anchors for the ropes; the iron stakes ran out before they were halfway up, and after that the climbers used horn and sharpened bone. And the men kicked, driving the spikes on their boots against the hard unyielding ice again and again and again and again to make one foothold. Their legs must be numb, Jon thought by the fourth hour. How long can they keep on with that? He watched as restless as the Magnar, listening for the distant moan of a Therm warhorn. But the horns stayed silent, and there was no sign of the Night's Watch.
By the sixth hour, Jarl had moved ahead of Grigg the Goat again, and his men were widening the gap. "The Mance's pet must want a sword," the Magnar said, shading his eyes. The sun was high in the sky, and the upper third of the Wall was a crystalline blue from below, reflecting so brilliantly that it hurt the eyes to look on it. Jarl's four and Grigg's were all but lost in the glare, though Errok's team was still in shadow. Instead of moving upward they were edging their way sideways at about five hundred feet, making for a chimney. Jon was watching them inch along when he heard the sound — a sudden crack that seemed to roll along the ice, followed by a shout of alarm. And then the air was full of shards and shrieks and falling men, as a sheet of ice a foot thick and fifty feet square broke off from the Wall and came tumbling, crumbling, rumbling, sweeping all before it. Even down at the foot of the ridge, some chunks came spinning through the trees and rolling down the slope. Jon grabbed Ygritte and pulled her down to shield her, and one of the Therms was struck in the face by a chunk that broke his nose.
And when they looked up Jarl and his team were gone. Men, ropes, stakes, all gone; nothing remained above six hundred feet. There was a wound in the Wall where the climbers had clung half a heartbeat before, the ice within as smooth and white as polished marble and shining in the sun. Far far below there was a faint red smear where someone had smashed against a frozen pinnace.
The Wall defends itself, Jon thought as he pulled Ygritte back to her feet.
They found Jarl in a tree, impaled upon a splintered branch and still roped to the three men who lay broken beneath him. One was still alive, but his legs and spine were shattered, and most of his ribs as well. "Mercy," he said when they came upon him. One of the Therms smashed his head in with a big stone mace. The Magnar gave orders, and his men began to gather fuel for a pyre.
The dead were burning when Grigg the Goat reached the top of the Wall. By the time Errok's four had joined them, nothing remained of Jarl and his team but bone and ash.
