So, when Sir Lancelot saw Queen Guinevere rejoiced to hear his wanderings and adventures, he resolved to set forth yet again, and win more worship still, that he might more increase her favour.  Then he bade his cousin Sir Lionel make ready, “for,” said he, “we two will seek adventure.”  So they mounted their horses—­armed at all points—­and rode into a vast forest; and when they had passed through it, they came to a great plain, and the weather being very hot about noontide, Sir Lancelot greatly longed to sleep.  Then Sir Lionel espied a great apple-tree standing by a hedge, and said, “Brother, yonder is a fair shadow where we may rest ourselves and horses.”

“I am full glad of it,” said Sir Lancelot, “for all these seven years I have not been so sleepy.”

So they alighted there, and tied their horses up to sundry trees; and Sir Lionel waked and watched while Sir Lancelot fell asleep, and slept passing fast.

In the meanwhile came three knights, riding as fast flying as ever they could ride, and after them followed a single knight; but when Sir Lionel looked at him, he thought he had never seen so great and strong a man, or so well furnished and apparelled.  Anon he saw him overtake the last of those who fled, and smite him to the ground; then came he to the second, and smote him such a stroke that horse and man went to the earth; then rode he to the third, likewise, and struck him off his horse more than a spear’s length.  With that he lighted from his horse, and bound all three knights fast with the reins of their own bridles.

When Sir Lionel saw this he thought the time was come to prove himself against him, so quietly and cautiously, lest he should wake Sir Lancelot, he took his horse and mounted and rode after him.  Presently overtaking him, he cried aloud to him to turn, which instantly he did, and smote Sir Lionel so hard that horse and man went down forthwith.  Then took he up Sir Lionel, and threw him bound over his own horse’s back; and so he served the three other knights, and rode them away to his own castle.  There they were disarmed, stripped naked, and beaten with thorns, and afterwards thrust into a deep prison, where many more knights, also, made great moans and lamentations, saying, “Alas, alas! there is no man can help us but Sir Lancelot, for no other knight can match this tyrant Turquine, our conqueror.”

But all this while, Sir Lancelot lay sleeping soundly under the apple-tree.  And, as it chanced, there passed that way four queens, of high estate, riding upon four white mules, under four canopies of green silk borne on spears, to keep them from the sun.  As they rode thus, they heard a great horse grimly neigh, and, turning them about, soon saw a sleeping knight that lay all armed under an apple-tree; and when they saw his face, they knew it was Lancelot of the Lake.
