Book V - Chapter III - How King Arthur held a parliament at York, and how he ordained the realm should be governed in his absence.
NOW leave we of Lucius the Emperor and speak we of King Arthur, that commanded all them of his retinue to be ready at the utas of Hilary for to hold a parliament at York. And at that parliament was concluded to arrest all the navy of the land, and to be ready within fifteen days at Sandwich, and there he showed to his army how he purposed to conquer the empire which he ought to have of right. And there he ordained two governors of this realm, that is to say, Sir Baudwin of Britain, for to counsel to the best, and Sir Constantine, son to Sir Cador of Cornwall, which after the death of Arthur was king of this realm. And in the presence of all his lords he resigned the rule of the realm and Guenever his queen to them, wherefore Sir Launcelot was wroth, for he left Sir Tristram with King Mark for the love of Beale Isould. Then the Queen Guenever made great sorrow for the departing of her lord and other, and swooned in such wise that the ladies bare her into her chamber. Thus the king with his great army departed, leaving the queen and realm in the governance of Sir Baudwin and Constantine. And when he was on his horse he said with an high voice, If I die in this journey I will that Sir Constantine be mine heir and king crowned of this realm as next of my blood. And after departed and entered into the sea at Sandwich with all his army, with a great multitude of ships, galleys, cogs, and dromounds, sailing on the sea.
