'O Lancelot, Lancelot,' he said, 'what a man of words thou art! If thou darest to battle with me, cease thy babbling, man, and come off, and let us ease our hearts with strong blows.'

Then Sir Lancelot issued forth with many of his knights, and a covenant was made between the hosts that there should be no fighting until Sir Gawaine and Sir Lancelot had fought together, and one was either dead or yielden.

Thereupon the two knights departed some way and then came together with all the might of their horses, and each smote the other in the midst of the shield. So strong were the knights and stout and big the spears, that their horses could not stand the shock, and so fell to the ground.

Then the knights quickly avoided their horses and dressed their shields, and fought fiercely together with their swords. So valiantly did each give and receive blows, and so heavy and grim was their fighting, that all the knights and lords that stood thereabout marvelled thereat and were fain to say, in as many good words, that never had they seen such sword-play.

In a little while, so shrewd and skilful were they, both were wounded and the blood oozed from the joints of their armour, and it was great marvel to see that they could still stand, dashing their shields upon each other, and each beating upon the other with great slashes of their swords.

And which was the stronger of the twain none might say.

Now Sir Gawaine had a magic power, which had been endowed upon him at his birth by a great witch who was a friend of his mother, the sorceress, Queen Morgan le Fay, wife of King Lot. No one knew of this secret power except King Arthur, and often had it availed Sir Gawaine, so that in dire perils of onfall, sudden ambush, or long battle, it had given him the victory, when all about him had been slain or wounded or taken captive.

The magic was that, from the hour of nine until high noon, the strength of his body increased until it was three times his natural strength, which itself was full great, though in that, for deep wind and breath and might of arm, Sir Lancelot was the stronger.

Now while they fought together, Sir Lancelot felt that Sir Gawaine seemed not to weaken as time went on, and he marvelled greatly. Then he felt that indeed Sir Gawaine's strength was greater than it had been at the beginning, and a fear came into his heart that Sir Gawaine was possessed of a demon.

But Sir Lancelot was stout of heart as well as old in warcraft, and knew that if he could tire Sir Gawaine he might, by one blow, get the better of him when he saw a good chance. Therefore Sir Lancelot began to husband his strength, and instead of spending it in feinting and attacking, he bore his shield ever before him, covering himself from the fierce blows of his enemy.

Thus he kept up his own strength; but hard put to it was he when, towards midday, Sir Gawaine seemed to have the might of a very giant, and the shield arm of Sir Lancelot was numbed by reason of the crashing blows which Sir Gawaine's sword rained upon it.

Great travail indeed had Sir Lancelot to stand up and not to yield; and while men marvelled how he could endure, none knew all he suffered.

Then, as the bell of the convent in the town boomed forth the hour of noon, Sir Gawaine heaved up his sword for a final blow; but his sword descended just as the last stroke of twelve had died away, and Sir Lancelot marvelled to feel that what should have been so grievous a blow that, belike, he could not have stood before it, fell upon his shield with no more than the strength of the blow given by an ordinary man.

When Sir Lancelot felt the might of Sir Gawaine so suddenly give way, he drew himself up to his full height and said:

'Sir Gawaine, I know not by what evil power ye have fought, but now I feel that ye have done. Now, my lord, Sir Gawaine, I must do my part, for none may know the great and grievous strokes I have endured this day with great pain.'

With that Sir Lancelot redoubled his blows, and the sword of Sir Gawaine gave before the might of Sir Lancelot, and his shield was rent.

Then Sir Lancelot gave so great a buffet on the helm of the other that Sir Gawaine staggered, and with yet another blow Sir Lancelot hurled him headlong to the ground.

Men held their breath, for now, after so fierce and stubborn a struggle, they felt sure that Sir Lancelot, hot and enraged against his enemy, would rip off the other's helm and strike his head off instantly.

But, instead, Sir Lancelot stood for a moment looking at his prostrate enemy. Then men gasped to see him thrust his sword into its scabbard with a clang, turn on his heel and begin to walk away.

They saw the p.r.o.ne knight raise his head and look as if in surprise at the retreating figure of Sir Lancelot.

'Why dost thou depart?' cried Sir Gawaine, rage in his mocking voice.

'Turn again, false knight, and slay me! If ye leave me thus, thou shalt gain nothing from it, for when I am whole I will slay thee when I may.'

Men marvelled to hear a fallen foe use such shameful and hateful words, but they marvelled much more when Sir Lancelot, turning, cried:

'I shall endure you, sir, if G.o.d give me grace; but wit you well. Sir Gawaine, I will never smite you to death.'

Many that before had hated Sir Lancelot were moved by these n.o.ble words, and by the sight of his mercy; and they deemed that there was hardly another man in all Christendom that would have shown such n.o.bility, save Sir Galahad and Sir Perceval, and they were dead.

So Sir Lancelot went into the city, and Sir Gawaine was borne into King Arthur's tent and his wounds were cleaned and salved. Thus he lay for three weeks, hard of mood and bitter in his hatred, and longing eagerly to get well, so he might try again to slay Sir Lancelot. Meanwhile he prayed the king to attack Sir Lancelot's walls, to try to draw him forth, or to take the city by treachery.

But the king would do naught. He was sick for sorrow because of the war that was between him and Sir Lancelot, and by reason of the wounds of his nephew Sir Gawaine.

'Alas,' was ever his reply, 'neither you nor I, my nephew, will win worship at these walls. For we make war for no reason, with as n.o.ble a knight as ever drew breath, and one more merciful and courteous than any that ever graced the court of any Christian king.'

'Nevertheless,' replied Sir Gawaine, raging at the king's love for Sir Lancelot, 'neither his mercy nor courtesy would avail against my good sword, once I could sink it in his treacherous heart.'

As soon as Sir Gawaine might walk and ride, he armed him at all points and mounted a great courser, and with a long wide spear in his hand he went spurring to the great gate of the town.

'Where art thou, Lancelot?' he cried in a fierce voice. 'Come thou forth, traitor knight and recreant! I am here to revenge me on thy evil body for thy treacherous slaughter of my twain brothers.'

All this language Sir Lancelot heard, and leaning from the tower he thus spake:

'Sir Gawaine, it sorrows me that ye will not cease your foul speaking.

I know your might, and all that ye may do, and well ye wot ye may do me great hurt or death.'

'Come down, then,' cried Sir Gawaine, 'for what my heart craves is to slay thee. Thou didst get the better of me the other day, and I come this day to get my revenge. And wit thee well I will lay thee as low as thou didst lay me.'

'I will not keep ye waiting long,' said Sir Lancelot, 'for as ye charge me of treachery ye shall have your hands full of me erelong, however the battle between us may end.'

Then happened it even as before. The knights encountered first with spears, but Sir Gawaine's broke into a hundred pieces on the shield of Sir Lancelot. Then, dismounting, the knights fought on foot with swords.

Sir Gawaine put forth all his strength, hoping, with the magic power which he possessed, to dash Sir Lancelot to his knees. But Sir Lancelot was more wary than before, and under cover of his shield he husbanded his strength until the hour of noon, when, as before, he felt that Sir Gawaine's might had strangely ebbed away.

When that had come to pa.s.s, Sir Lancelot said:

'Now once more have I proved that ye fight not with a man's fair strength, Sir Gawaine, but with some evil power. And full grievously was I put to it to withstand many of thy sad blows. Now ye have done your great deeds, and I will do mine.'

Then with one stroke, of so marvellous a force that men marvelled, Sir Lancelot beat down Sir Gawaine's guard, and struck him a full heavy blow on the side of the helm, beating it in so that the old wound burst again.

Sir Gawaine fell to the ground, and for some moments lay still as if he were dead or in a swoon; but he was only dazed, and soon recovering, he raved and foamed as he lay there, cursing Sir Lancelot for a traitorous coward and a base knight, and even, in his madness, thrusting towards him with his sword.

'Wit thou well, base knight,' he cried, 'that I am not slain yet. Come thou near and lie here with me, and we will fight this battle until we die.'

'I will do no more than I have done, my lord,' said Sir Lancelot, 'and when thou art able to stand I will meet thee again. But to smite a wounded man that may not stand, I will not.'

Then Sir Lancelot withdrew to the town, while Sir Gawaine still raved and abused him, and men marvelled both at the exceeding madness of the hatred of Sir Gawaine and the great restraint and n.o.bleness of Lancelot. Many said that had Sir Gawaine said half as many shameful things to one of them, they would have instantly rased his evil head from his shoulders.

For a month Sir Gawaine lay sick, but was always eager to be up and able again. And at length the leech said that in three days he should ride, whereat Sir Gawaine was joyful.

'Again,' said he to King Arthur, who sat beside him, 'again shall I have to do with that base fellow, and ill attend me if I do not end the matter this time.'

'Ye had ended it long ago, or been ended,' said the king, 'except for the n.o.bleness of Sir Lancelot that forbore to slay you.'

'Ay, we all know your love of the pestilent fool, uncle,' said Sir Gawaine, 'but we will stay here until we have made an end of him and his kingdom, if it take us all our lives.'

Even as he spoke there came the clear call of a trumpet outside in the camp, and Sir Bedevere came to the door of the king's tent, his grim old face pale, his grizzled hair unkempt, and every sign of haste and travel upon his dress.

The king started up. 'Sir Bedevere, ye bring evil tidings from Britain,' he cried. 'Can it be that more ruin and wrong is to come than that I suffer now? What is your news?'

'O my king, it is that Mordred your nephew hath rebelled,' said Sir Bedevere, 'and has gathered much people about him, and hath sent many letters to all the lords and knights your va.s.sals, promising them wealth and lands if they make him king. And Gwenevere your queen he hath imprisoned, saying that he will wed her when ye are slain.'
