The Scots, without the siege equipment to invest the Castle, encamped around it. The week that followed saw constant skirmishes and challenges to single combat between the two sides, that culminated when Douglas challenged Hotspur to a duel. In the ensuing joust Douglas successfully felled Hotspur and was able to capture his pennon. According to Froissart, Douglas announced that he would ""carry pennon to Scotland and hoist it on my tower, where it may be seen from afar"", to which Hotspur retorted ""By God! You will never leave Northumberland alive with that.""
