According to Taliesin the Anglian king Ulph "came with violence on his enemies" and was met in battle and killed by Urien map Cynfarch, King of Rheged (probably Cumbria and/or Galloway), and his son Owain mab Urien, as noted in two separate poems.
Segundo Taliesin o rei anglo Ulph "veu con violencia cara aos seus inimigos" e foi atopado en batalla e asasinado por Urien map Cynfarch, rei de Rheged (probabelmente Cumbria e/ou Galloway), e o seu fillo Owain mab Urien, como se cita en dous poemas distintos.
