When Sir Lancelot heard how Sir Plenorius had spared Sir Brune, he said:
"You are a gentle knight. I am sorry you are vowed to the service of Lord Brian of the Isles. He shall surely die."
Sir Plenorius answered:
"When he is dead, I will come to Arthur's Court as one of his followers."
All this time Sir Brune was lying in a swoon on the bed in the turret room. But at last he came to himself and looked about him. He saw near him his sword and shield; so he lifted them up beside him. As he lay still, trying to recover his strength, he heard stealthy footsteps coming up the turret stairs. They came nearer and nearer. Suddenly, in rushed Lord Brian of the Isles. He knew that Sir Brune was there, alone and wounded, and he intended to kill him as he lay defenseless. Sir Brune understood this and he cried:
"Ah, wretch, you were ever a coward. You come to kill me as I lie wounded here, just as you killed my poor father while he slept. But the sight of you makes me forget my wounds."
At these words, and at the fierce rage which shone in Sir Brune's eyes, Lord Brian, who was indeed a coward, tried to retreat. But Sir Brune sprang to the doorway.
"You shall never go down by these stairs, villain," he said, "for I will kill you!"
Lord Brian rushed to the window and sprang out upon the battlements. Sir Brune followed him, though with difficulty. The two began to fight, and Sir Brune soon saw that his enemy was trying to push him close to the edge of the battlements, that he might fall down into the courtyard below.
Sir Brune, at this, put himself behind Lord Brian, determined to cast him off instead. Slowly he pushed him, until Lord Brian was but a step from the edge. Then Sir Brune lifted his shield and struck his enemy with it. The wicked lord lost his footing, and was dashed to pieces at the feet of Sir Lancelot and Sir Plenorius in the courtyard below.
