The Battle

History & Significance

The capture of Harlech — Edward I's most formidable Welsh castle — was the high point of Glyndŵr's revolt. He used it as his court, held parliaments there, received French ambassadors, and proclaimed himself Prince of Wales. His family lived there. The subsequent English siege lasted from 1408 to 1409 — the castle held by Glyndŵr's son-in-law Edmund Mortimer who died in the siege.
