And the sun shone very clear and strong—yet not too strong. And the breeze blew very freely so that all the poplar trees around about the castle were turned white with its blowing, and the river that ran down past the castle was dusked and rippled by that wind, and all the reeds of the river bowed and dipped into the water thereof.

So those two knights prepared themselves for the assault, making their armor in all ways tight and secure. Then when they were in all ways ready, they shouted to their horses and so sprang to the charge, galloping against one another with a noise like to the noise of thunder.

So they met in the midst of the course and smote one another, in the centre of the other’s shield. And before that shock the spear of each was split into a great many very small pieces, even to the hand that held it. And each horse sank quivering back upon its haunches at the recoil of that blow, and would have fallen, were it not that the extraordinary address of the knight rider recovered his horse with spur and rein and voice. Then each knight cast aside the truncheon of his spear and drew his sword, and each rushed at the other very furiously and valiantly. Then each smote the other with great power and strength.

Sir Launcelot faileth.

But though Sir Launcelot smote with all of his strength, yet Sir Gawaine smote with the strength of ten. So that Sir Launcelot was driven backward, and around and around in small circles, and in that assault he was altogether astonished at the fury and the strength of Sir Gawaine. For he wist not that Sir Gawaine had that strength of ten men, and he knew not that Sir Gawaine had taken that medicine to lend him that strength.

And Sir Launcelot had much ado to defend himself so that he made no attack, but only a defence with sword and shield against the attack of Sir Gawaine. And Sir Launcelot thought that never in all of his life had he fought with so strong and so powerful a knight as Sir Gawaine—nay, not even when he fought with Sir Turquine that day at the ford before the castle of Sir Turquine. For anon the blood began to flow forth from him in spite of all his defence, so that in a little while the ground on which he fought was all sprinkled red with that blood, and his armor was all ensanguined with the crimson streams that bathed it. And in all that while Sir Gawaine had hardly any wounds at all, but he fought with all his strength and might, and with the purpose to beat down his assailant.

But though Sir Gawaine fought in that wise, yet, by and by, it reached the prime of noon, and still he had not struck down Sir Launcelot. Then that strength of ten that he had with the medicine that he had taken began to fade and wane away as the flame of a candle flickers and wanes away when the wax is consumed. So anon Sir Launcelot felt that the attack of Sir Gawaine was no longer so furious and so violent as it had been, but that it was weaker. Therewith he redoubled his own battle with tenfold violence. And now he no longer made defence, but instead of defence he made attack. And he drave Sir Gawaine backward before him, for Sir Gawaine could not stand before the fierceness of that attack now that his strength was waning.

Sir Gawaine faileth and is overthrown.

So Sir Gawaine bore back from before those blows, and by and by he began to hold his shield full low for weariness. Then Sir Launcelot perceived his opening, so he rushed the attack with double fury, and anon he swung his sword and smote Sir Gawaine with it full upon the head. And so violent was that blow that it clave asunder the helmet and the coif, and it wounded the head beneath the coif.

Then Sir Gawaine sank down upon his knees, his hand relaxed and the sword that was in his hand fell out from it upon the ground. Then Sir Launcelot ran to Sir Gawaine and he set his foot upon the sword and he rushed off the helmet of Sir Gawaine and he cried out very fiercely, “Sir, yield yourself to me or I will slay you!” But Sir Gawaine said, “I will not yield me to thee, so thou mayst slay me at thy pleasure!” Then Sir Launcelot gazed at Sir Gawaine, and as he gazed at him the fury of battle passed away from his soul like a mist from before the face of the sun; and Sir Launcelot felt such great love for Sir Gawaine and such great pity for him that his eyes ran all with tears.
