So the quest of the Holy Graal had been fulfilled, and the few Knights that had been left alive returned to the Round Table, and there was great joy in the Court. To do them honour the Queen made them a dinner; and there were four and twenty Knights present, and among them Sir Patrise of Ireland, and Sir Gawaine and his brethren, the King's nephews, which were Sir Agrawaine, Sir Gaheris, Sir Gareth, and Sir Mordred. Now it was the custom of Sir Gawaine daily at dinner and supper to eat all manner of fruit, and especially pears and apples, and this the Queen knew, and set fruit of all sorts before him. And there was present at the dinner one Sir Pinel le Savage, who hated Sir Gawaine because he and his brethren had slain Sir Lamorak du Galis, cousin to Sir Pinel; so he put poison into some of the apples, hoping that Sir Gawaine would eat one and die. But by ill fortune it befell that the good Knight Sir Patrise took a poisoned apple, and in a few moments he lay dead and stark in his seat. At this sight all the Knights leapt to their feet, but said nothing, for they bethought them that Queen Guenevere had made them the dinner, and feared that she had poisoned the fruit.

'My lady, the Queen,' said Sir Gawaine, who was the first to speak, 'this fruit was brought for me, for all know how well I love it; therefore, Madam, the shame of this ill deed is yours.' The Queen stood still, pale and trembling, but kept silence, and next spoke Sir Mador de la Porte.

'This shall not be ended so,' said he, 'for I have lost a noble Knight of my blood, and I will be avenged of the person who has wrought this evil.' And he turned to the Queen and said 'Madam, it is you who have brought about the death of my cousin Sir Patrise!' The Knights round listened in silence, for they too thought Sir Mador spake truth. And the Queen still said nothing, but fell to weeping bitterly, till King Arthur heard and came to look into the matter. And when they told him of their trouble his heart was heavy within him.

'Fair lords,' said the King at last, 'I grieve for this ill deed; but I cannot meddle therein, or do battle for my wife, for I have to judge justly. Sure I am that this deed is none of hers, therefore many a good Knight will stand her champion that she be not burned to death in a wrong quarrel. And, Sir Mador, hold not your head so high, but fix the day of battle, when you shall find a Knight to answer you, or else it were great shame to all my Court.'

'My gracious lord,' said Sir Mador, 'you must hold me excused. But though you are a King you are also a Knight, and must obey the laws of Knighthood. Therefore I beseech your forgiveness if I declare that none of the four and twenty Knights here present will fight that battle. What say you, my lords?' Then the Knights answered that they could not hold the Queen guiltless, for as the dinner was made by her either she or her servants must have done this thing.

'Alas!' said the Queen, 'no evil was in my heart when I prepared this feast, for never have I done such foul deeds.'

'My lord the King,' cried Sir Mador, 'I require of you, as you are a just King, to fix a day that I may get ready for the fight!'

'Well,' answered the King, 'on the fifteenth day from this come on horseback to the meadow that is by Westminster. And if it happens that there be a Knight to fight with you, strike as hard as you will, God will speed the right. But if no Knight is there, then must my Queen be burned, and a fire shall be made in the meadow.'

'I am answered,' said Sir Mador, and he and the rest of the Knights departed.

When the King and Queen were left alone he asked her what had brought all this about. 'God help me, that I know not,' said the Queen, 'nor how it was done.'

'Where is Sir Lancelot?' said King Arthur, looking round. 'If he were here he would not grudge to do battle for you.'

'Sir,' replied the Queen, 'I know not where he is, but his brother and his kinsmen think he is not in this realm.'

'I grieve for that,' said the King, 'for he would soon stop this strife. But I counsel you, ask Sir Bors, and he will not refuse you. For well I see that none of the four and twenty Knights who were with you at dinner will be your champion, and none will say well of you, but men will speak evil of you at the Court.'

'Alas!' sighed the Queen, 'I do indeed miss Sir Lancelot, for he would soon ease my heart.'

'What ails you?' asked the King, 'that you cannot keep Sir Lancelot at your side, for well you know that he who Sir Lancelot fights for has the best Knight in the world for his champion. Now go your way, and command Sir Bors to do battle with you for Sir Lancelot's sake.' So the Queen departed from the King, and sent for Sir Bors into her chamber, and when he came she besought his help.

'Madam,' said he, 'what can I do? for I may not meddle in this matter lest the Knights who were at the dinner have me in suspicion, for I was there also. It is now, Madam, that you miss Sir Lancelot, whom you have driven away, as he would have done battle for you were you right or wrong, and I wonder how for shame's sake you can ask me, knowing how I love and honour him.'

'Alas,' said the Queen, 'I throw myself on your grace,' and she went down on her knees and besought Sir Bors to have mercy on her, 'else I shall have a shameful death, and one I have never deserved.' At that King Arthur came in, and found her kneeling before Sir Bors. 'Madam! you do me great dishonour,' said Sir Bors, raising her up.

'Ah, gentle Knight,' cried the King, 'have mercy on my Queen, for I am sure that they speak falsely. And I require by the love of Sir Lancelot that you do battle for her instead of him.'

'My lord,' answered Sir Bors, 'you require of me the hardest thing that ever anyone asked of me, for well you know that if I fight for the Queen I shall anger all my companions of the Round Table; but I will not say nay, my lord, for Sir Lancelot's sake and for your sake! On that day I will be the Queen's champion, unless a better Knight is found to do battle for her.'

'Will you promise me this?' asked the King.

'Yes,' answered Sir Bors, 'I will not fail you nor her, unless there should come a better Knight than I, then he shall have the battle.' Then the King and Queen rejoiced greatly, and thanked Sir Bors with all their hearts.

So Sir Bors departed and rode unto Sir Lancelot, who was with the hermit Sir Brasias, and told him of this adventure. 'Ah,' said Sir Lancelot, 'this has befallen as I would have it, and therefore I pray you make ready to do battle, but delay the fight as long as you can that I may appear. For I am sure that Sir Mador is a hot Knight, and the longer he waits the more impatient he will be for the combat.'

'Sir,' answered Sir Bors, 'let me deal with him. Doubt not you shall have all your will.' And he rode away, and came again to the Court.

It was soon noised about that Sir Bors would be the Queen's champion, and many Knights were displeased with him; but there were a few who held the Queen to be innocent. Sir Bors spoke unto them all and said, 'It were shameful, my fair lords, if we suffered the most noble Queen in the world to be disgraced openly, not only for her sake, but for the King's.' But they answered him: 'As for our lord King Arthur, we love him and honour him as much as you; but as for Queen Guenevere, we love her not, for she is the destroyer of good Knights.'

'Fair lords,' said Sir Bors, 'you shall not speak such words, for never yet have I heard that she was the destroyer of good Knights. But at all times, as far as I ever knew, she maintained them and gave them many gifts. And therefore it were a shame to us all if we suffered our noble King's wife to be put to death, and I will not suffer it. So much I will say, that the Queen is not guilty of Sir Patrise's death; for she owed him no ill will, and bade him and us to the dinner for no evil purpose, which will be proved hereafter. And in any case there was foul dealing among us.'

'We may believe your words,' said some of the Knights, but others held that he spoke falsely.

The days passed quickly by until the evening before the battle, when the Queen sent for Sir Bors and asked him if he was ready to keep his promise.

'Truly, Madam,' answered he, 'I shall not fail you, unless a better Knight than I am come to do battle for you. Then, Madam, I am discharged of my promise.'

'Shall I tell this to my lord Arthur?' said the Queen.

'If it pleases you, Madam,' answered Sir Bors. So the Queen went to the King, and told him what Sir Bors had said, and the King bade her to be comforted, as Sir Bors was one of the best Knights of the Round Table.

The next morning the King and Queen, and all manner of Knights, rode into the meadow of Westminster, where the battle was to be; and the Queen was put into the Guard of the High Constable, and a stout iron stake was planted, and a great fire made about it, at which the Queen should be burned if Sir Mador de la Porte won the fight. For it was the custom in those days that neither fear nor favour, love nor kinship, should hinder right judgment. Then came Sir Mador de la Porte, and made oath before the King that the Queen had done to death his cousin Sir Patrise, and he would prove it on her Knight's body, let who would say the contrary. Sir Bors likewise made answer that Queen Guenevere had done no wrong, and that he would make good with his two hands. 'Then get you ready,' said Sir Mador. 'Sir Mador,' answered Sir Bors, 'I know you for a good Knight, but I trust to be able to withstand your malice; and I have promised King Arthur and my Lady the Queen that I will do battle for her to the uttermost, unless there come forth a better Knight than I am.'

'Is that all?' asked Sir Mador; 'but you must either fight now or own that you are beaten.'

'Take your horse,' said Sir Bors, 'for I shall not tarry long,' and Sir Mador forthwith rode into the field with his shield on his shoulder, and his spear in his hand, and he went up and down crying unto King Arthur, 'Bid your champion come forth if he dare.' At that Sir Bors was ashamed, and took his horse, and rode to the end of the lists. But from a wood hard by appeared a Knight riding fast on a white horse, bearing a shield full of strange devices. When he reached Sir Bors he drew rein and said, 'Fair Knight, be not displeased, but this battle must be to a better Knight than you. For I have come a great journey to fight this fight, as I promised when I spoke with you last, and I thank you heartily for your goodwill.' So Sir Bors went to King Arthur and told him that a Knight had come who wished to do battle for the Queen. 'What Knight is he?' asked the King.

'That I know not,' said Sir Bors; 'but he made a covenant with me to be here this day, and now I am discharged,' said Sir Bors.

Then the King called to that Knight and asked him if he would fight for the Queen. 'For that purpose I came hither,' replied he, 'and therefore, Sir King, delay me no longer, for as soon as I have ended this battle I must go hence, as I have many matters elsewhere. And I would have you know that it is a dishonour to all the Knights of the Round Table to let so noble a lady and so courteous a Queen as Queen Guenevere be shamed amongst you.'

The Knights who were standing round looked at each other at these words, and wondered much what man this was who took the battle upon him, for none knew him save Sir Bors.

'Sir,' said Sir Mador de la Porte unto the King, 'let me know the name of him with whom I have to do.' But the King answered nothing, and made a sign for the fight to begin. They rode to the end of the lists, and couched their spears and rushed together with all their force, and Sir Mador's spear broke in pieces. But the other Knight's spear held firm, and he pressed on Sir Mador's horse till it fell backward with a great fall. Sir Mador sprang from his horse, and, placing his shield before him, drew his sword, and bade his foe dismount from his horse also, and do battle with him on foot, which the unknown Knight did. For an hour they fought thus, as Sir Mador was a strong man, and had proved himself the victor in many combats. At last the Knight smote Sir Mador grovelling to his knees, and the Knight stepped forward to have struck him flat upon the ground. Therewith Sir Mador suddenly rose, and smote the Knight upon the thigh, so that the blood ran out fiercely. But when the Knight felt himself wounded, and saw his blood, he let Sir Mador rise to his feet, and then he gave him such a buffet on the helm that this time Sir Mador fell his length on the earth, and the Knight sprang to him, to unloose his helm. At this Sir Mador prayed for his life, acknowledging that he was overcome, and confessed that the Queen's innocence had been proved. 'I will only grant you your life,' said the Knight, 'if you will proclaim publicly that you have foully slandered the Queen, and that you make no mention, on the tomb of Sir Patrise, that ever Queen Guenevere consented to his murder.' 'All that will I do,' said Sir Mador, and some Knights took him up, and carried him away to heal his wounds. And the other Knight went straight to the foot of the steps where sat King Arthur, and there the Queen had just come, and the King and the Queen kissed each other before all the people. When King Arthur saw the Knight standing there he stooped down to him and thanked him, and so likewise did the Queen; and they prayed him to put off his helmet, and commanded wine to be brought, and when he unlaced his helmet to drink they knew him to be Sir Lancelot du Lake. Then Arthur took the Queen's hand and led her to Sir Lancelot and said, 'Sir, I give you the most heartfelt thanks of the great deed you have done this day for me and my Queen.'

'My lord,' answered Sir Lancelot, 'you know well that I ought of right ever to fight your battles, and those of my lady the Queen. For it was you who gave me the high honour of Knighthood, and that same day my lady the Queen did me a great service, else I should have been put to shame before all men. Because in my hastiness I lost my sword, and my lady the Queen found it and gave it to me when I had sore need of it. And therefore, my lord Arthur, I promised her that day that I would be her Knight in right or in wrong.'

'I owe you great thanks,' said the King, 'and some time I hope to repay you.' The Queen, beholding Sir Lancelot, wept tears of joy for her deliverance, and felt bowed to the ground with sorrow at the thought of what he had done for her, when she had sent him away with unkind words. Then all the Knights of the Round Table and his kinsmen drew near to him and welcomed him, and there was great mirth in the Court.
