The Battle of Otterburn took place according to Scottish sources on 5 August 1388, or 19 August according to English sources as part of the continuing border war between England and Scotland. Partly fought in the moonlight, it was a victory for the Scots, led by James Douglas, 2nd Earl of Douglas, over Harry Hotspur, son of the Earl of Northumberland. Douglas was killed in the battle, though his victory added to the prestige of his house, foremost among the border fighters of Scotland.
