Owain Glyndŵr's Wales
Battle of Hyddgen
Glyndwr's victory over the King's forces at Hyddgen, in the summer of 1401, turned him from a local rebel to a national leader. The exact location of the battle of Hyddgen is unknown, but the probable site is a remote area of the Pumlumon Mountain range, most likely the high ridge to the west of Pumlumon Fawr.
Not much is known of the battle but Glyndwr gained an important victory against overwhelming odds, comprised mainly of forces of a mixed Welsh-Flemish stock from Pembrokeshire.
The nearest approach by road to Hyddgen is at Maes Nant and from there leads a track going South-North, possibly the route the sizeable Pembrokeshire force followed on their way to do battle with Glyndwr's much smaller army, waiting for them at Owain's probable base camp of Siambr Trawsfynydd.
The land surrounding the ridge near Pumlumon Fawr is boggy today, as it would have been in the fifteenth century, and the nearby river probably also proved strategic in the battle.
Two quartz blocks, known as Cerrig Cyfamod Glyndwr ('Glyndwr's Covenant Stones') are said to mark the site of the battle but it is unlikely given the terrain. They can be reached by going left from the track and crossing the stream and fence.
There is a tradition that the dead of the battle were buried at Esgair y Ffordd, a little to the north of the battle-site and marked by a cairn.
