Battle of Tryfrwyd

The Battle of Tryfrwyd (or Tribruit) was the tenth battle fought by Arthur as Dux Bellorum, mentioned in a number of early Welsh sources, amongst them the eleventh century poem Pa Gur and the works of the chronicler Nennius. Alongside Arthur, Manawydan fab Llyr and Cai the Tall are recorded as having fought in the battle; it is implied that the latter defeated a soldier (possibly chieftain) by the name of Garwlwyd during the conflict.
