  ====''A Game of Thrones''====
  Roose is amongst the lords who travel to Winterfell to aid Robb Stark in his campaign against the Lannisters. His intelligence and caution sees him given command of part of the Northern host when the army splits up at the Twins, and he leads the attack on Tywin Lannister's army in the Battle of the Green Fork. The battle ends in a Lannister victory and Roose retreats with the survivors to the causeway of Moat Cailin.
