Under Jack's watch, King-Beyond-the-Wall Raymun Redbeard and his free folk host slipped past the Wall and headed south. This drew the forces of House Umber and House Stark to Long Lake, where Raymun and Lord Willam Stark were killed in battle. The Night's Watch arrived too late to participate in the battle and were ordered by Artos Stark to dispose of the dead. This series of events led Sleepy Jack to earn his nickname.
