In a sample chapter for the Winds of Winter, Theon overhears the following conversation from Stannis:
"Bolton has blundered," the king declared. "All he had to do was sit inside his castle whilst we starved. Instead he has sent some portion of his strength forth to give us battle.
From Theon's previous chapters in Dance, we know that everyone is on edge in Bolton's camp, even Roose himself:
Roose Bolton said nothing at all. But Theon Greyjoy saw a look in his pale eyes that he had never seen before-an uneasiness, even a hint of fear.
Given what we know today (prior to the release of TWOW), did Roose Bolton blunder in sending out a large portion of his forces, or was it a tactical necessity given the deteriorating situation of the men under his command?
