Owain Glyndwr was a descendant of the Princes of Powys from his father Gruffudd Fynchan II, Lord of Glyndyfrdwy. Glyndwr was born in 1354 to a prosperous landed family, part of the Anglo-Welsh gentry of the Welsh Marches. Owain probably studied as a legal apprentice at the Inns of Court in London as a young man. In 1383 he returned to Wales, married and established himself as the Squire of Sycharth and Glyndyfrdwy. In the late 1390's he quarelled with his neighbour Lord Grey over some lands and was unable to obtain redress from King Henry IV. Glyndwr lost the legal case and was under personal threat and in January 1400 serious civil disorder broke out and this led to Owain being proclaimed Prince of Wales on 16th.September 1400 by a band of followers. Then began a guerilla campaign against the English Lords of the Marches which soon became a war of independance. In 1402 the English Parliament issued Penal Laws against Wales and in 1403 Glyndwr was defeated by Henry IV at the battle of Shrewsbury. In 1405 a formal treaty between Wales and France was negotiated and French forces landed at Milford Haven and marched on Worcester. They met the English army but for reasons that have never been clear both sides withdrew and by 1406 the French forces had left Wales. Owain remained free and the revolt continued. In 1412 Owain Glyndwr captured Dafydd Gam ("Crooked David") a leading Welsh supporter of the English King Henry and later ransomed him. This was the last flash of the revolt and the last time that Owain was seen alive by his enemies. Nothing certain is known of Owain after 1412. It is thought that Owain finally spent his last years with his daughter Alys, passing himself off as an ageing Franciscan friar at their home at Kentchurch near Abergavenny.
This cache is best done in conjunction with Sidetracked - Glyndyfrdwy as the recommended parking place is a lay by on the road to the station opposte the Memorial Hall. Walk back up the hill and take care crossing the main road (A5) which can be very busy. Do not drive up the entrance next to the hall as it is on a blind corner and exiting could be very dangerous.
