Then was King Arthur grieved, for he foresaw the ruin of his noble Order. And turning to Sir Gawain, he said: “Nephew, ye have done ill, for through you I am bereft of the noblest company of knights that ever brought honour to any realm in Christendom. Well I know that never again shall all of you gather in this hall, and it grieves me to lose men I have loved as my life and through whom I have won peace and righteousness for all my realm.” So the King mourned and his knights with him, but their oaths they could not recall.
Great woe was there in Camelot next day when, after worship in the cathedral, the knights who had vowed themselves to the Quest of the Holy Grail got to horse and rode away. A goodly company it was that passed through the streets, the townfolk weeping to see them go; Sir Launcelot du Lac and his kin, Sir Galahad of whom all expected great deeds, Sir Bors and Sir Percivale, and many another scarcely less famed than they. So they rode together that day to the Castle of Vagon, where they were entertained right hospitably, and the next day they separated, each to ride his own way and see what adventures should befall him.
So it came to pass that, after four days’ ride, Sir Galahad reached an abbey. Now Sir Galahad was still clothed in red armour as when he came to the King’s court, and by his side hung the wondrous sword; but he was without a shield. They of the abbey received him right heartily, as also did the brave King Bagdemagus, Knight of the Round Table, who was resting there. When they greeted each other, Sir Galahad asked King Bagdemagus what adventure had brought him there. “Sir,” said Bagdemagus, “I was told that in this abbey was preserved a wondrous shield which none but the best knight in the world might bear without grievous harm to himself. And though I know well that there are better knights than I, to-morrow I purpose to make the attempt. But, I pray you, bide at this monastery a while until you hear from me; and if I fail, do ye take the adventure upon you.” “So be it,” said Sir Galahad.
The next day, at their request, Sir Galahad and King Bagdemagus were led into the church by a monk and shown where, behind the altar, hung the wondrous shield, whiter than snow save for the blood-red cross in its midst. Then the monk warned them of the danger to any who, being unworthy, should dare to bear the shield. But King Bagdemagus made answer: “I know well that I am not the best knight in the world, yet will I try if I may bear it.” So he hung it about his neck, and, bidding farewell, rode away with his squire.
