In the A Song of Ice and Fire novels, Black Jack Bulwer is not killed in a wildling attack on Mole's Town. He survives the Battle of Castle Black. At some point he's named First Ranger. Later, Jon sends Jack Bulwer and eight more rangers to find Tormund. He and two of the others (Garth Greyfeather and Hairy Hal) are killed by the Wildling raider known as the Weeper, and their eyeless heads are brought to Castle Black.
