Then Sir Accalon was glad, and he hastened with the lady to the castle of Sir Ontzlake. They found him groaning because he was ill and because Sir Damas had sent him a challenge to fight with a knight, and he could not accept it. He was much relieved when Morgan le Fay told him that Sir Accalon would fight in his place.
Early in the afternoon, King Arthur and Sir Accalon rode into the field where the combat was to be held. Arthur did not know who Sir Accalon was, nor did any one else, except Morgan le Fay. Two sides of the field were full of people who came to watch, half of whom were friends of Sir Damas, and the other half were friends of Sir Ontzlake.
Arthur and Sir Accalon rode at each other so furiously that at the shock of the meeting both fell off their horses. Then they began to fight fiercely with their swords. The king could make no headway with his false steel, but whenever Sir Accalon struck at Arthur he drew blood.
The king was much amazed. He grew weaker and weaker, but still he kept on his feet. Those who watched him were sorry for him; they thought they had never seen a man fight so bravely. At last Arthur's sword broke, and fell in two pieces on the ground. When Sir Accalon saw this, he cried:
"I will never yield," said the king, "and if you do not get me another sword, you will be shamed before all men, for it is an unknightly thing to fight with a defenseless man."
"I do not care," said Sir Accalon. "If you will not yield, defend yourself with your shield as best you can."
He rushed at the king. Arthur was so weak that he could hardly stand, but he guarded himself as well as he could with his shield. Soon he could do no more, and fell to the ground.
At this moment the Lady of the Lake, who had given Arthur his sword, came upon the field. She was invisible, but anyone who had listened intently could have heard a sound like the ripple of water as she walked. She caused Excalibur to fall out of the hand of Sir Accalon and drop near Arthur.
When it fell, Arthur saw that it was his own Excalibur. He grasped its handle and some of his strength came back. He struggled to his feet, and rushing up to Sir Accalon, seized the scabbard of Excalibur and threw it far over the field.
