There were feasting the Soudan, ten kings, and many barons, when Sir Guy walked into the pavilion and delivered his message with great roughness of speech. "Seize him and slay him!" cried the Soudan. But Sir Guy cut his way through his assailants and rushing on the Soudan cut off his head; and while he stooped to pick up the trophy with his left hand, with his right he slew six Saracens, then fought his passage past them all to the tent door, and leapt upon his horse. But the whole Saracen host being roused he never would have got back for all his bravery, but that Heraud within the city saw in a dream the danger he was in, and assembling the Greek army and Sir Guy's knights, came to his rescue and put the Saracens to flight. Then after the battle, Sir Guy came in triumph to Constantinople and laid the Soudan's head at the feet of the Emperor Ernis.
Ernis now, being at peace from his enemies, would take Sir Guy through his realms. On their way they saw a dragon fighting a lion, and the lion having much the worst of the combat, Sir Guy must needs go and fight the dragon. After a hard battle he laid the monster dead at his feet, and the lion came and licked the hands of his deliverer, and would in no wise depart from his side.
Soon afterward the Emperor Ernis gathered a great company of princes, dukes, earls, barons, bishops, abbots, and priors to the wedding feast, and in presence of them all he gave Sir Guy to be ruler over half the kingdom, and led forth the Princess Loret to be his bride.
But when Sir Guy saw the wedding-ring, his old love came to his mind, and he bethought him of Felice. "Alas!" he cried, "Felice the bright and beautiful, my heart misgives me of forgetting thee. None other maid shall ever have my love." Then he fell into a swoon and when he came to himself he pleaded sudden sickness. So the marriage was put off, to the great distress of Ernis and his daughter Loret, and Sir Guy gat him to an Inn. Heraud tended him there, and learned how it was for the sake of Felice that Guy renounced so fair a bride, dowered with so rich a kingdom. But after a fortnight, when he could no longer feign illness because of the watchfullness of the Emperor and the Princess after his health, he was forced to return to court, and delay his marriage from day to day by one excuse and another, until at length fortune delivered him from the strait. The lion which Sir Guy had tamed was used to roam about the palace, and grew so gentle that none feared him and none sought him harm. But Sir Morgadour, being sore vexed to think that all his plans against Sir Guy had failed, determined to wreak his spite upon the lion. He therefore watched until he found the lion asleep within an arbour, and then wounded him to death with his sword. The faithful beast dragged himself so far as Sir Guy's chamber, licked his master's hands, and fell dead at his feet. But a little maid which had espied Sir Morgadour told Sir Guy who had slain his lion. Then Sir Guy went forth in quest of Sir Morgadour, and fought with him and slew him. He had forgiven the wrongs against himself, since he outwitted them; but he was fain to avenge his faithful favourite. Now Sir Morgadour was steward to the German Emperor Regnier. So Sir Guy showed Ernis that if he remained longer at his court, Regnier would surely make war on Greece to avenge his steward's death. Wherefore with this excuse he took his departure and set sail with Heraud in the first ship he could find. They landed in Germany, and visited the Emperor Regnier without telling anything about his steward's death. Then they came to Lorraine.
As Sir Guy took his way alone through a forest, having sent his servants on to prepare a place for him at an inn, he heard the groaning of a man in pain, and turning his horse that way, found a knight sore wounded, and like to die. This knight was named Sir Thierry, and served the Duke of Lorraine. He told how he was riding through the wood with his lady, Osile, when fifteen armed men beset him, and forcibly carried off the lady to take her to Duke Otho of Pavia, his rival Then said Sir Guy, "I also have a score to settle with Otho, the felon duke." Then he took Sir Thierry's arms and armour, and went in pursuit of the ravishers whom he soon overtook, and having slain every one, he set the lady on his steed and returned to the place where he had left the wounded knight. But now Sir Thierry was gone; for four knights of Duke Otho's band had come and carried him off. So Sir Guy set down the lady, and started to find the four knights. Having fought and vanquished them, he set Sir Thierry on his horse and returned. But now Osile was gone. He searched for many hours to find her, but in vain. So as nightfall drew on he took Sir Thierry to the inn. There by good fortune they found the lady, Sir Guy's servants having met her in the wood and brought her with them to await his coming. A leech soon came and dressed Sir Thierry's wounds, and by the careful tending of Osile and Sir Guy, he got well Then Sir Guy and Sir Thierry swore brotherhood in arms.
Soon there came a messenger, saying that Duke Otho, hotly wroth at losing the fair Osile, had gone to lay waste the lands of Aubry, Sir Thierry's father; the Duke of Lorraine was likewise helping him. Thereupon Sir Guy equipped five hundred knights and came with Sir Thierry to the city of Gurmoise where Aubry dwelt. It was a well ramparted city, and after being beaten in two battles with Sir Guy, Duke Otho found, despite the larger numbers of his host, that he could not stand against the courage of the little army and the valour of its leader. Thinking therefore to gain Osile by treachery, he sent an archbishop to Aubry, offering peace and pledging himself to confirm the marriage of Sir Thierry and Osile, provided only that the lovers would go and kneel in homage to their sovereign Duke of Lorraine. Thereon Sir Thierry and his bride, together with Sir Guy and Sir Heraud, set out unarmed, and after wending a day's journey out of Gurmoise, they met the Duke of Lorraine, who embraced and kissed them in token of peace. But Otho coming forward as if to do the like, made a sign to a band of men whom he had in waiting to seize them. These quickly surrounded Sir Heraud and Sir Thierry and carried them off; but Sir Guy with only his fists slew many of his assailants, and broke away to where a countryman stood with a staff in his hand. Snatching this for a weapon, Sir Guy beat down the quickest of his pursuers, and made his escape. Duke Otho cast Sir Thierry into a deep dungeon in Pavia, and meanwhile gave Osile a respite of forty days wherein to consent to be his bride. But the Duke of Lorraine carried off Sir Heraud.
Weary and hungered, and vexed at the loss of his friends, Sir Guy came to a castle where he sought harbour for the night. Sir Amys of the Mountain, who dwelt there, welcomed him with a good will, and hearing his adventures, offered to raise an army of fifteen hundred men to help him against Duke Otho. But to this Sir Guy said nay, because it would take too long. So, after a day or two, having hit upon a plan, he disguised, himself by staining his face and darkening his hair and beard and eyebrows; and setting out alone, came to Duke Otho with a present of a war-horse of great price, and said, "You have in your keeping a dastard knight by name Sir Thierry, who has done me much despite, and I would fain be avenged upon him." Then Duke Otho, falling into the trap, appointed him jailor of Sir Thierry.
The dungeon wherein Sir Thierry was prisoned was a pit of forty fathoms deep, and very soon Sir Guy spake from the pit's mouth bidding him be of good cheer, for he would certainly deliver him. But a false Lombard overheard these words, and thereby knowing that it was Sir Guy, ran off straightway to tell Duke Otho. Sir Guy followed quickly and sought to bribe the man with money to hold his peace, but without avail, for he would go into the palace where the Duke was, and opened his mouth to tell the tale. Then with one blow Sir Guy slew him at Duke Otho's feet. But Otho, very wroth, would have killed Sir Guy then and there, only that he averred that this was a certain traitor whom he found carrying food to the prisoner. Thus having appeased the Duke's anger, he gat away secretly to Osile, and bade her change her manner to Duke Otho, and make as though she was willing to have his love. The night before the day fixed for the wedding, Sir Guy let down a rope to Thierry in his pit, and having drawn him up, the two made all speed to the castle of Sir Amys. There, getting equipped with arms and armour, they leaped to horse on the morrow, and riding back to Pavia, met the wedding procession. Rushing into the midst Sir Guy slew Otho and Sir Thierry carried off Osile, whereupon they returned to Sir Amys with light hearts. And when the Duke of Lorraine had tidings of what had befallen Otho he had great fear of Sir Guy, and sent Sir Heraud back with costly gifts to make his peace. So Sir Thierry and Osile were wed, and a sumptuous banquet was held in their honour, with game, and hunting, and hawking, and justing, and singing of glee-men, more than can be told.
Now as Sir Guy went a-hunting one day, he rode away from his party to pursue a boar of great size. And this boar, being very nimble and fleet of foot, led him a long chase till he came into Flanders. And when he killed the boar he blew upon his horn the prize. Florentine, King of Flanders, hearing it in his palace, said, "Who is this that slays the tall game on my lands?" And he bade his son go forth and bring him in. The young prince coming with a haughty message to Sir Guy, the knight struck him with his hunting-horn, meaning no more than chastisement for his discourtesy. But by misadventure the prince fell dead at his feet. Thinking no more of the mishap, and knowing not who it was whom he had slain, Sir Guy rode on to the palace, and was received with good cheer at the King's table. But presently the prince's body being brought in, and Guy owning that he had done this deed, King Florentine took up an axe, and aimed a mighty blow at the slayer of his son. This Sir Guy quickly avoided, and when all arose to seize him, he smote them down on either hand, and fought his way through the hall till he reached his steed, whereon lightly leaping he hasted back to Sir Thierry.
Then after a short while he took leave of Sir Thierry, and came with Sir Heraud to England, to the court of King Athelstan at York. Scarce had he arrived there when tidings came that a great black and winged dragon was ravaging Northumberland, and had destroyed whole troops of men which went against him. Sir Guy at once armed himself in his best proven armour, and rode off in quest of the monster. He battled with the dragon from prime till undern, and on from undern until evensong, but for all the dragon was so strong and his hide so flinty Sir Guy overcame him, and thrust his sword down the dragon's throat, and having cut off his head brought it to King Athelstan. Then while all England rang with this great exploit, he took his journey to Wallingford to see his parents. But they were dead; so after grieving many days for them he gave his inheritance to Sir Heraud, and hasted to Felice at Warwick.
