Dafydd Gam

Dafydd ap Llewelyn ap Hywel (c. 1380 – 25 October 1415), better known as Dafydd Gam, anglicized to David or Davy Gam, was a Welsh warrior, a prominent opponent of Owain Glyndŵr. He died at the Battle of Agincourt fighting for Henry V, King of England in that victory against the French.

The epithet "Gam" is a soft-mutated form of the Welsh word "cam" (one-eyed, cross-eyed). As the University of Wales Dictionary notes "according to tradition, Syr Dafydd Gam (Dafydd ap Llewelyn ap Hywel Fychan) was one-eyed or cross-eyed". Regarded by Welsh nationalists as a traitor, Gam is regarded as a hero by others; his reputation has waxed and waned with those of his enemy Owain Glyndŵr and his ally King Henry V.
