When Tristan came back to that land, King Mark and all his Barony were mourning; for the King of Ireland had manned a fleet to ravage Cornwall, should King Mark refuse, as he had refused these fifteen years, to pay a tribute his fathers had paid. Now that year this King had sent to Tintagel, to carry his summons, a giant knight; the Morholt, whose sister he had wed, and whom no man had yet been able to overcome: so King Mark had summoned all the barons of his land to Council, by letters sealed.
On the day assigned, when the barons were gathered in hall, and when the King had taken his throne, the Morholt said these things: "King Mark, hear for the last time the summons of the King of Ireland, my lord. He arraigns you to pay at last that which you have owed so long, and because you have refused it too long already he bids you give over to me this day three hundred youths and three hundred maidens drawn by lot from among the Cornish folk. But if so be that any would prove by trial of combat that the King of Ireland receives this tribute without right, I will take up his wager. Which among you, my Cornish lords, will fight to redeem this land?"
The barons glanced at each other but all were silent.
Then Tristan knelt at the feet of King Mark and said: "Lord King, by your leave I will do battle."
