Excerpt from The Dream of Rhonabwy, circa 1200
Then a proud and handsome man of bold and eloquent speech said that it was a wonder how a large force could be contained in such a confined area, the more so as they had promised to be at the Battle of Baddon by noon in order to fight against Osla Big Knife. "You may choose to go or not to go, but I will go," he said, and Arthur answered, "What you say is true. We will set out together." "Iddawg, who is the man who spoke so boldly to Arthur?" asked Rhonabwy. "A man who has the right to speak as bluntly as he wishes: Caradawg Strong Arm, son of Llyr of the Sea, Arthur's chief adviser and his first cousin." (Page 183)
