In hand-to-hand fighting before the walls of Newcastle, Douglas is said to have won Sir Henry's pennon, which he swore to fix upon the walls of Dalkeith.
The Scots then retreated to Otterburn, where Percy, who was bent on recovering his pennon, attacked them on a fine August evening in 1388.
But the banner of the banneret always implied a more or less extensive command, while every knight was entitled to bear a pennon and every squire a pencel.
But the creation is almost the self-same with that in the old French ceremonies by the solemn delivery of a banner charged with the arms of him that is to be created, and the cutting of the end of the pennon or streamer to make it a square or into the shape of a banner in case that he which is to be created had in the field his arms on a streamer before the creation."
This event is celebrated every June in the ceremony of "Riding the Common" - in which a facsimile of the captured pennon is carried in procession to the accompaniment of a chorus "Teribus, ye Teri Odin," supposed to be an invocation to Thor and Odin - a survival of Northumbrian paganism.
