"I have another plan," Gendry said. "As far as I know, the Wildlings don't just cross the Wall. There are other routes into the North?"
"The Wall has never completely sealed off the North. At Eastwatch-by-the-Sea, raiders can build small boats, slip past Eastwatch-by-the-Sea, and enter the Bay of Seals. In the western mountains, they slip into the dark depths of the Great Gorge and go around the Shadow Tower. But in the middle, they can only face the Wall," Samwell said.
"That Horn of Winter Mance has is a fake. But even so, the wight army could come across the sea or through the Great Gorge..." Gendry studied the map.
"How is that possible?"
"Nothing is impossible," Gendry said. "If heavy snow falls. If the sea freezes."
"So the Night's Watch and the Wall are the first line of defense. I'll concentrate the reinforcements near Eastwatch-by-the-Sea and the Shadow Tower. They'll reinforce the second line."
That was Gendry's thinking: first, divide the defense into two lines.
Divide responsibility for the Wall and make full use of the terrain.
Perhaps the Horn of Winter would not be needed. Once the sea froze, war would come immediately.
When that happened, swift reinforcement by the Iron Cavalry and the Magic Dragons would be especially important.
Besides that, Gendry might also have to witness the election of the Night's Watch's Commander-in-Chief at the Wall.
"Open the gates!" Big Riddle bellowed, his voice like a thunderclap.
Seven hundred feet above, the sentries heard the shout and blew their war horns. The calls echoed over the Wall, between heaven and earth.
At both ends of the long tunnel, the gates opened and the iron bars were removed.
The way through the Wall had never been particularly wide. It was little more than a passage.
