Of the sorrow that King Arthur made for the war, and of another battle where also Sir Gawaine had the worse. Alas, said the king, that ever this unhappy war was begun; for ever Sir Launcelot forbeareth me in all places, and in likewise my kin, and that is seen well this day by my nephew Sir Gawaine. Then King Arthur fell sick for sorrow of Sir Gawaine, that he was so sore hurt, and because of the war betwixt him and Sir Launcelot. So then they on King Arthur’s part kept the siege with little war withoutforth; and they withinforth kept their walls, and defended them when need was. Thus Sir Gawaine lay sick three weeks in his tents, with all manner of leech-craft that might be had. And as soon as Sir Gawaine might go and ride, he armed him at all points, and start upon a courser, and gat a spear in his hand, and so he came riding afore the chief gate of Benwick; and there he cried on height: Where art thou, Sir Launcelot? Come forth, thou false traitor knight and recreant, for I am here, Sir Gawaine, will prove this that I say on thee.

And then Sir Launcelot armed him at all points, and mounted upon his horse, and gat a great spear in his hand, and rode out at the gate. And both the hosts were assembled, of them without and of them within, and stood in array full manly. And both parties were charged to hold them still, to see and behold the battle of these two noble knights. And then they laid their spears in their rests, and they came together as thunder, and Sir Gawaine brake his spear upon Sir Launcelot in a hundred pieces unto his hand; and Sir Launcelot smote him with a greater might, that Sir Gawaine’s horse’s feet raised, and so the horse and he fell to the earth. Then Sir Gawaine deliverly avoided his horse, and put his shield afore him, and eagerly drew his sword, and bade Sir Launcelot: Alight, traitor knight, for if ............
