A Dance With Dragons
Halleck joins the defense of the Wall under Lord Commander Jon Snow against the Others along with other free folk. Jon considers re-garrisoning Deep Lake or Sable Hall with men under the command of Halleck, although neither castle is ready for human habitation yet. Jon later tells Torghen Flint that both castles have been garrisoned, although they are undermanned.
