His prowess in the great battle of Cattraeth against the Saxons is commemorated by the contemporary poet Aneurin, who is the same as the sour Gildas, historian of the Britons:—
“When Caradoc rushed into the battle
It was like the tearing onset of the woodland boar,
The bull of combat in the field of slaughter,
He attracted the wild dogs by the motion of his hand.
My witnesses are Owen ap Eulat
And Gwrien, and Gwynn and Gwriat.
From Cattraeth and its carnage,
From the battle encounter,
After the clear bright mead was served,
