The hill of Craig-y-dorth, is near to the village of Cwmcarvan (Welsh: Cwmcarfan) in Monmouthshire (Sir Fynwy) in south-east Wales. In this month, August 1404, it was the site of a battle between Owain Glyndŵr's forces and those of the English. Glyndŵr was victorious and the defeated English forces were either slain or put to flight.
