The Night’s Watch prepares for the wildling invasion. Gilly and her son arrive at Castle Black, where Sam hides them in an underground room. The wildlings attack from both sides. Tormund’s army gets through from the south and engages the Night’s Watch. One giant manages to break through the tunnel leading into Castle Black but is killed by Grenn and five others, at the cost of their own lives. Alliser Thorne goes to fight in the southern part, leaving Janos Slynt in charge. However, Slynt proves to be incompetent and is tricked into going down the main level, effectively leaving Jon in charge. After watching Jon kill Styr, Ygritte prepares to kill him but is shot by Olly. Jon holds her in his arms as she dies. With the help of Jon’s direwolf, Ghost, the Night’s Watch secure the ground level of Castle Black, leading to Tormund’s arrest. The wall climbers are obliterated by a massive scythe launched by the Watch. The wildlings retreat but not for long, Jon predicts. Seeing no other choice, Jon goes beyond the Wall to find and kill Mance Rayder.
