[4] His troops inflicted a series of defeats on the English forces and captured key castles across Wales, rapidly gaining control of most of the country.
[5] In 1403 a Welsh army including a French contingent, commanded by Owain Glyndŵr, his senior general Rhys Gethin and Cadwgan, Lord of Glyn Rhondda, defeated a large English invasion force reputedly led by King Henry IV himself at the Battle of Stalling Down in Glamorgan.
Glyndŵr was cornered and besieged at Harlech Castle, but he managed to escape by disguising himself as an elderly man, slipping past the enemy at night.
He retreated to the wilderness with a band of loyal supporters, continuing the war with guerrilla tactics throughout Wales and the English borderlands.
[8] With his death, Owain acquired a mythical status along with Cadwaladr, Cynan and Arthur as a folk hero awaiting the call to return and liberate his people, Y Mab Darogan (The Foretold Son).
[9] On the 600th anniversary of Glyndŵr's Welsh Revolt in 2000, celebrations took place across Wales including Ruthin, where the uprising against the English had begun in 1400.
[16] Children from Betws Gwerfil Goch and Gwyddelwern schools also make presentations, before the Cambrian Band marches onwards to the statue of Glyndŵr.
[23] Most notably, the parade and wreath-laying ceremony at Corwen was cancelled, although organisers decided to continue with the church service, lecture and community meal as planned.
[28] The announcement prompted the actor and activist Michael Sheen to post a video on social media, questioning whether the palace knew the king’s visit clashed with Glyndŵr day, which he described as "insensitive to the point of insult" or if the visit was arranged in ignorance of it, which led Sheen to ask "what being Prince of Wales for so long actually meant if you were not aware of what that day means?"
Sheen ended his video with what many interpreted as opposition to the continued use of the Prince of Wales title, quoting Lily Smalls, Mrs Beynon's maid, from Dylan Thomas's Under Milk Wood: The day of the Royal visit was marked by a number of protests.
