Quoth Arthur the king: "Sir Lancelot, of this thing it behoves ye take better rede; lightly might it turn to my shame if all my knights rode forth, and I thereafter were beset with strife and warfare, as full oft hath chanced aforetime! So might it in sooth be mine undoing. It hath chanced afore this that I had lost crown and lands, save for my knights; by them have I been victorious!"
Quoth Sir Lancelot: "By the Lord who made me, and who shall be Doom's-man at the last day, come what may thereof, since Sir Gawain rideth hence 'tis not I will bide behind! Rather will I try what may chance, and adventure all that God hath given me, for he sought me with all his power when I was in secret case, and brought me once more to court—for that do I owe him faith and fellowship."
Then they all wept, wives and maidens, knights and squires, when they knew Sir Lancelot would ride thence.
Sir Gawain, who forgat not the wounded knight and his need of healing, went to him as he lay, and bound up his wounds, and so tended him at that time that he was healed ere long—needs must he be healed, even against his will, on whom Sir Gawain laid hands. All they of the court were sad and sorry at their departing; that eve they ate but little, for thinking of the knights who should ride forth with the morning.
But now will we be silent on their lamentations, and tell henceforth of Sir Gawain and Sir Lancelot, who rode both on their way.
The adventure doeth us to wit that in the morning, so soon as it was day, they rode forth together through many a waste land, over many a heath and high hill, adown many a valley to seek Sir Perceval, but little did it profit them, for of him might they learn naught. Thus were they sorely vexed.
On the ninth day there came riding towards them a knight on a goodly steed, and well armed withal. He was all black, even as I tell ye: his head, his body, and his hands were all black, saving only his teeth. His shield and his armour were even those of a Moor, and black as a raven. He rode his steed at full gallop, with many a forward bound. When he beheld the knights, and drew nigh to them, and the one had greeted the other, he cried aloud to Sir Lancelot: "Knight, now give me to wit of one thing which I desire, or guard ye against my spear. The truth will I know. I shall tell ye herewith my custom; what knight soever I may meet, were he stronger than five men, and I knew it well, yet would I not hold my hand for fear or favour, but he should answer me, or I should fight against him. Now, Sir Knight, give me answer, by your troth, so truly as ye know, to that which I shall ask ye, and delay not, otherwise may ye well rue it!"
Quoth Sir Lancelot: "I were liefer dead than that a knight should force me to do that to which I had no mind—so were the shame equal. Hold to your custom an ye will; I were more fain to fight than to let ye be, if but to fell your pride. I ask naught but peace, yet will I chastise your discourtesy, or die in that will!"
The Moor, who was wroth with Sir Lancelot, abode not still, but reined back his steed, and laid his spear in rest as one who was keen to fight. Sir Gawain drew on one side, since the twain would fight, and thought in himself, as was right and courteous, that it were folly, and the custom of no good knight, for twain to fall on one man, since life stood not at stake. 'Twere time enough for him to take hand therein, and stand by his comrade, did he see him hard pressed. Therefore stood Sir Gawain still, as one who had no mind to fight, nor to break the laws of courtesy. Nevertheless he deemed that this was a devil rather than a man whom they had come upon! Had they not heard him call upon God no man had dared face him, deeming that he was the devil or one of his fellows out of hell, for that his steed was so great, and he was taller even than Sir Lancelot, and black withal, as I said afore.
