That is hard to do, said Sir Launcelot, for by Sir Tristram I may have a warning, for when by means of treaties, Sir Tristram brought again La Beale Isoud unto King Mark from Joyous Gard, look what befell on the end, how shamefully that false traitor King Mark slew him as he sat harping afore his lady La Beale Isoud, with a grounden glaive he thrust him in behind to the heart. It grieveth me, said Sir Launcelot, to speak of his death, for all the world may not find such a knight. All this is truth, said Sir Bors, but there is one thing shall courage you and us all, ye know well King Arthur and King Mark were never like of conditions, for there was never yet man could prove King Arthur untrue of his promise.
So to make short tale, they were all consented that for better outher for worse, if so were that the queen were on that morn brought to the fire, shortly they all would rescue her. And so by the advice of Sir Launcelot, they put them all in an embushment in a wood, as nigh Carlisle as they might, and there they abode still, to wit what the king would do.
