The problem was that they had been short on food ever since House Whitehill had come after the Red Wedding and looted most of their supplies and money. A big part of what they managed to gather later was sent to Stannis. He got a few men to scale the steep mountain facade that was protecting the back of Ironrath in the night to forage for food, but it barely kept them afloat and only slowed the inevitable. Everyone had been eating small rations for a sennight already, and were slowly getting thinner. But surrender was not going to be an option, knowing how they rebelled against the flayed man, and with the animosity House Whitehill had for the Forresters, none of them were getting out of here alive. They were to be used as an example for other rebellious Houses.
