Quoth Sir Gawaine, “Prepare yourself then for battle!” So Sir Bors took his assigned place and when they were in all wise prepared they rushed together with great violence and fury.
In that encounter the spear of each knight was broken into many pieces, even to the very fist that held the spear, and the horse of each recoiled so that it sunk back upon its haunches and would, perhaps, have fallen, had not the address of the knight rider recovered it. Then each knight cast aside the truncheon of his spear and voided his horse, and each drew his sword with great readiness and rushed to the battle very furiously, violently and impetuously. Each smote the other many sore buffets and strokes so that each knight was wounded in several places.
But Sir Gawaine was possessed of the strength of ten, and Sir Bors was possessed but of the strength of one, so that by and by Sir Bors was obliged to hold his shield low because of weariness from the redoubled fury of Sir Gawaine’s attack.
Sir Gawaine woundeth Sir Bors.
So Sir Gawaine perceived that opening which he made in his defence, and, grinding his teeth together, he whirled up his sword and smote Sir Bors upon the shoulder of that arm that held his sword. So violent and savage was the blow that it sheared through the iron of the epulier and it sheared through the flesh and bone of the shoulder so that the arm of Sir Bors fell and hung down from the shoulder and his hand dropped the sword that he held.
Sir Bors asks his life.
Then Sir Gawaine laughed and ran forward and he set his foot upon the sword of Sir Bors. And Sir Bors sank down upon his knees and he said in a weak and faltering voice, “Sir Gawaine, I am sorely wounded. If it please thee to do so, I pray thee to spare my life.”
Quoth Sir Gawaine, “Why should I spare thee thy life? Thou art a traitor knave, and it is not fit that I should spare thee, but rather I should slay thee as thou kneelest before me. But I cannot forget our long and many associations; and I cannot forget that thou wert one of those three knights who achieved the Grail, and brought the Grail back again to Sarras. So I will forgive thee, and will spare thee thy life, if so be that God will also spare it.”
Then Sir Gawaine turned and sheathed his sword, and he mounted his horse and rode away. And anon there came the friends of Sir Bors from the Castle of Chillion, and they lifted him up and laid him upon a litter, and so they bore him away into the castle.
And they took Sir Bors to a room of the castle and stripped off his armor and beheld the wound that it was very ghastly and dismal. And so much blood was emitted from that wound that Sir Bors fainted and for awhile he hung hovering upon the edge of death.
