We know Tewdric's battle against the Saxons took place in or near Tintern. Tintern is famous today for its ruined Cistercian abbey nestled against the banks of the River Wye, but of course the abbey didn't exist before the 12th century, 700 years after Tewdric. In the 5th century Tintern would have looked very different compared to today.
The actual site of Tewdric's battle is disputable, but I very much doubt it would have been fought on flat, open ground given the overwhelming odds against Tewdric's army so I rule out the Wye's floodplain. It is far more likely in my view that Tewdric would have chosen high ground, forcing the Saxons to fight uphill, hence putting them at a disadvantage. What we do know is that Tewdric was mortally wounded during the fight.
Legend has it that Tewdric, knowing he was dying, asked to be carried to Ynys Echni (Flat Holm Island) to be buried and that he was borne away on a carriage or cart pulled by two yoked stags. We are also told his journey from Tintern to Mathern, where Tewdric died, took three days. They must have travelled very slowly since the distance between Tintern and Mathern by ancient footpaths is only around 8.5 miles.
