'Wit ye well, my lord, that we feel great scorn of the evil words which Sir Gawaine spoke unto you when that ye parleyed with him, and also of these shameful names which men call upon ye for all the citizens to hear. Wherefore, we charge you and beseech you, if ye will to keep our service, hold us no longer behind these walls, but let us out, in the name of Heaven and your fair name, and have at these rascals.'
'Fair friends,' replied Sir Lancelot, 'I am full loth to fight against my dear lord, King Arthur.'
'But if ye will not,' said Sir Lionel, his brother, 'all men will say ye fear to stir from these walls, and hearing the shameful words they cry, will say that there must be truth in them if ye seek not to silence them.'
They spoke long with Sir Lancelot, and at length he was persuaded; and he sent a message to the king telling him that he would come out and do battle; but that, for the love he bore the king, he prayed he would not expose his person in the fight.
But Sir Gawaine returned answer that this was the king's quarrel, and that the king would fight against a traitor knight with all his power.
On the morrow, at nine in the morning, King Arthur drew forth his host, and Sir Lancelot brought forth his array. When they stood facing each other, Sir Lancelot addressed his men and charged all his knights to save King Arthur from death or wounds, and for the sake of their old friendship with Sir Gawaine, to avoid battle with him also.
Then, with a great hurtling and crashing, the knights ran together, and much people were there slain. The knights of Sir Lancelot did great damage among the king's people, for they were fierce knights, and burned to revenge themselves for the evil names they had heard.
Sir Gawaine raged like a lion through the field, seeking Sir Lancelot, and many knights did he slay or overthrow. Once, indeed, King Arthur, dashing through the fight, came upon Sir Lancelot.
'Now, Sir Lancelot,' he cried, 'defend thee, for thou art the causer of this civil war.'
At these words he struck at Sir Lancelot with his sword; but Sir Lancelot took no means to defend himself, and put down his own sword and shield, as if he could not put up arms against his king. At this the king was abashed and put down his sword, and looked sorrowfully upon Sir Lancelot.
