The Battle of Winterfell is a battle late in the War of the Five Kings, in which King Stannis Baratheon attempts to take Winterfell from Lord Roose Bolton, the Lannister-backed Warden of the North. The swift defeat of the weakened Baratheon army marks the end of the campaign to take the Iron Throne led by King Stannis, who perishes after the battle. However, the Boltons' hold on the North is severely weakened by the escape of Sansa Stark during the battle.
