Around May 1405 Richard Grey 1st or 4th Baron Grey of Codnor (age 34) and Dafydd Gam Brecon (age 25) decisively defeated the Welsh army at the Battle of Pwll Melyn aka Usk. Gruffudd ab Owain Glyndŵr Mathrafal (age 30) was captured. Tudur ap Gruffudd Mathrafal Lord Gwyddelwern (age 48) was killed. The Welsh lost around 1500 men with 300 prisoners being beheaded following the battle. The battle marked the beginning of the end of Owain Glyndŵr's (age 46) revolt.
