How Sir Launcelot Fell Into the Greatest Peril that Ever He Encountered in all His Life. Also How He Freed a Misfortunate Castle and Town From the Giants Who Held Them, and How He Released the Lord Thereof From a Dungeon.  
Now Sir Launcelot wandered errant for many days, meeting no adventure of any moment, but taking great joy in all that he beheld of the wide world about him, and in that time he found lodging wheresoever he chanced to be (if not in house, then beneath the skies), and he endured all sorts of weather, both wet and dry.
Sir Launcelot cometh to a fair valley with a castle.
 
Upon a certain day, in the prime of the morning, he came across a hilltop, and beheld beneath him a valley, very fertile and well-tilled, with fields and meadow-lands spread all over it like to a fair green carpet woven in divers patterns. And in the midst of the valley was a very large and noble castle, with many towers, and tall, steep roofs, and clustering chimneys. So Sir Launcelot descended into that valley, and the road which he took ended in front of the castle and under the shade of the tall gray walls thereof. But he did not stop at that castle but went on by it.
 
Now after Sir Launcelot had passed by that castle it seemed to him that he heard very delicate silver bells ringing sweetly in the air above him, and when he looked up he beheld that a falcon was flying over his head toward a high elm tree that stood at a little distance, and he wist that it was the bells upon the cap of the falcon that rang so sweetly. And Sir Launcelot beheld that long lunes hung from the feet of the falcon as she flew, wherefore he was aware that the falcon had slipped her lunes and had flown from her owner.
Sir Launcelot beholdeth a falcon entangled.
Sir Launcelot climbs to catch the lady's falcon
 
So Sir Launcelot watched the falcon, and he beheld that she lit in a tall elm tree, where she took her perch and rested, balancing with her wings part spread. Then by and by she would have taken her flight again, but the lunes about her feet had become entangled around the bough on which she sat, so that when she would have flown she could not do so. Now Sir Launcelot was very sorry to see the falcon beating herself in that wise, straining to escape from where she was prisoner, but he knew not what to do to aid her, for the tree was very high, and he was no good climber of trees.
 
While he stood there watching that falcon he heard the portcullis of the castle lifted, with a great noise, and the drawbridge let fall, and therewith there came a lady riding out of the castle very rapidly upon a white mule, and she rode toward where Sir Launcelot watched the falcon upon the tree. When that lady had come nigh to Sir Launcelot, she cried out to him: "Sir Knight, didst thou see a falcon fly this way?" Sir Launcelot said: "Yea, Lady, and there she hangs, caught by her lunes in yonder elm-tree."
 
Then when that lady beheld how that her falcon hung there she smote her hands together, crying out: "Alas, alas! what shall I do? That falcon is my lord's favorite hawk! While I was playing with her a while since, she slipped from me and took flight, and has sped as thou dost see. Now when my lord findeth that I have lost his hawk in that wise he will be very angry with me, and will haply do me some grievous hurt."
The Lady beseeches Sir Launcelot to get her the falcon again.
 
Quoth Sir Launcelot: "Lady, I am very sorry for you." "Sir," she said, "it boots nothing for you to be sorry for me unless you can aid me." "How may I aid you in this?" said Sir Launcelot. "Messire," quoth she, "how otherwise could you aid me than by climbing up into this tree for my hawk? For if you aid me not in such a fashion, I know not what I shall do, for my lord hath a very hot and violent temper, and he is not likely to brook having his favorite hawk lost to him, as it is like to be."
 
Upon this Sir Launcelot was put to a great pass and knew not what to do, for he had no good mind to climb that tree. "Lady," quoth he, "I prithee tell me what is thy lord's name." "Messire," she replied, "he is hight Sir Phelot, and is a knight of the court of the King of North Wales."
 
"Well, Lady," said Sir Launcelot, "thou dost put upon me a very sore task in this, for God knoweth I am no climber of trees. Yea, I would rather do battle with twenty knights than to climb one such tree as this. Nevertheless, I cannot find it in me to refuse the asking of any lady, if so be it lieth at all in my power to perform her will. Now if you will aid me to unarm myself, I will endeavor to climb this tree and get your hawk."
Sir Launcelot climbs the tree.
 
So the lady dismounted from her mule, and Sir Launcelot dismounted from his horse, and the lady aided Sir Launcelot to unarm himself. And when he had unarmed himself he took off all his clothes saving only his hosen and his doublet. Then he climbed that tree, though with great labor and pain to himself, and with much dread lest he should fall. So he, at last, reached the falcon where it was, and he loosened the lunes from where they were entangled about the branch, and he freed the bird. Then he brake off a great piece of rotten bough of the tree and he tied the lunes of the falcon to it and he tossed the falcon down to where the lady was; and the lady ran with great joy and caught the falcon and loosed it from the piece of branch and tied the lunes to her wrist, so that it could not escape again.
 
Then Sir Launcelot began to descend the tree with as great labor and pain as he had climbed into it.
Sir Phelot threatens Sir Launcelot's life.
 
But he had not come very far down when he perceived a knight who came riding very rapidly toward that tree, and he saw that the knight was in full armor. When this knight came to the tree he drew rein and bespoke the lady who was there, though Sir Launcelot could not hear what he said. So, after he had spoken for a little, the knight dismounted from his horse and went to Sir Launcelot's shield and looked upon the face of it very carefully. Then presently he looked upward toward Sir Launcelot, and he said: "Art thou Sir Launcelot of the Lake?" And Sir Launcelot said: "Yea." "Very well," said the knight, "I am pleased beyond measure at that. For I am Sir Phelot, the lord of this castle, and the brother of that Sir Peris of the Forest Sauvage, whom thou didst treat so shamefully after thou hadst overcome him in battle."
 
"Sir," said Sir Launcelot, "I treated him nowise differently from what he deserved." "No matter for that," said Sir Phelot, "he was my brother, and thou didst put great despite and shame upon him. So now I will be revenged upon thee, for now I have thee where I would have thee, and I will slay thee as shamefully as thou didst put shame upon him. So say thy prayers where thou art, for thou shalt never go away from this place alive."
 
"Sir Knight," said Sir Launcelot, "I do not believe that thou wouldst really assault a naked and harmless man, for it would certainly be a great shame to thee to do me a harm in that wise. For lo! thou art armed in full, and I am a naked man, and to slay me as I am would be both murder and treason."
 
"No matter for that," said Sir Phelot; "as for the shame of it, I take no thought of it. I tell thee thou shalt have no grace nor mercy from me. Wherefore make thy peace with Heaven, for thine hour is come."
 
"Sir Knight," said Sir Launcelot, "I ask only one boon of thee; if thou art of a mind to take so much shame upon thee, as appears to be the case, let me not, at least, die like a felon without any weapon. Let me have my sword in my hand, even if I have no other defence. For if a knight must die, it is a shame for him to die without weapons. So hang my sword upon yonder bough, where I may reach it, and then thou mayst slay me."
 
"Nay," said Sir Phelot, "I will not do that, for I know very well how wonderful is thy prowess. Wherefore I believe that even if thou wert otherwise unarmed thou mightst overcome me if thou hadst thy sword. So I will give thee no such chance, but will have my will of thee as thou art."
Sir Launcelot is put to a sad pass to escape.
 
Then Sir Launcelot was put to a great pass of anxiety, for he wist not what to do to escape from that danger in which he lay. Wherefore he looked all about him and above him and below him, and at last he beheld a great branch of the elm tree just above his head, very straight and tough. So he catched this branch and broke it off from the tree and shaped it to a club of some sort. Then he came lower, and the knight waited to strike him with his sword, when he was low enough; but Sir Launcelot did not come low enough for that.
 
Then Sir Launcelot perceived that his horse stood below him and a little to one side, so of a sudden he ran out along the branch whereon he stood and he leaped quickly down to the earth upon the farther side of his horse from where the knight stood.
Sir Launcelot overcomes Sir Phelot with a strange weapon.
 
At this Sir Phelot ran at him and lashed at him with his sword, thinking to slay him before he had recovered from his leap. But Sir Launcelot was quicker than he, for he recovered his feet and put away the blow of Sir Phelot with his club which he held. Then he ran in upon Sir Phelot under his sword arm, and before he could use his sword he struck Sir Phelot with all his might upon the side of his head. And he struck him very quickly again, and he struck him the third time, all in the space whilst one might count two. And those blows he struck were so direful that Sir Phelot fell down upon his knees, all stunned and bedazed, and the strength went out of his thews because of faintness. Then Sir Launcelot took the sword out of the hand of Sir Phelot and Sir Phelot did not have strength to deny him. And Sir Launcelot plucked off Sir Phelot's helm and catched him by the hair and dragged his neck forward so as to have ease to strike his head from off his body.
 
Now all this while the lady had been weeping and watching what befell. But when she saw the great danger Sir Phelot was in, she ran and clasped her arms about him, and cried out in a very loud and piercing voice upon Sir Launcelot to spare Sir Phelot and to slay him not. But Sir Launcelot, still holding him by the hair of the head, said: "Lady, I cannot spare him, for he has treated me more treacherously than any other knight with whom I ever had dealings." But the lady cried out all the more vehemently, "Sir Launcelot, thou good knight, I beseech thee, of thy knighthood, to spare him."
Sir Launcelot spares Sir Phelot's life.
 
"Well," said Sir Launcelot, "it hath yet to be said of me that I have denied anything that I was able to grant unto any lady that hath asked it of me upon my knighthood. And yet I know not how to trust either of ye. For thou didst not say one word in my behalf when I was in danger of being slain so treacherously just now. As for this knight, I perceive that he is every whit as great a traitor and a coward as was his brother Sir Peris of the Sauvage Forest. So I will spare him, but I will not trust him, lest he turn against me ere I arm myself again. Wherefore give me hither the halter rein of your mule." So the lady gave Sir Launcelot the halter rein, weeping amain as she did so. And Sir Launcelot took the halter rein and he tied the arms of Sir Phelot behind him. Then he bade the lady of Sir Phelot to help him arm himself from head to foot, and she did so, trembling a very great deal. Then, when she had done so, quoth Sir Launcelot: "Now I fear the treachery of no man." Therewith he mounted his horse and rode away from that place And he looked not behind him at all, but rode away as though he held too much scorn of that knight and of that lady to give any more thought to them.
 
So after that Sir Launcelot travelled for a while through the green fields of that valley, till by and by he passed out of that valley, and came into a forest through which he travelled for a very long time.
Sir Launcelot cometh to a marish country.
 
For it was about the slanting of the afternoon ere he came forth out of that forest and under the open sky again. And when he came out of the forest he beheld before him a country of perfectly level marish, very lush and green, with many ponds of water and sluggish streams bordered by rushes and sedge, and with pollard willows standing in rows beside the waters. In the midst of this level plain of green (which was like to the surface of a table for flatness) there stood a noble castle, part bu............
