So when Sir Nabon was thus in all wise prepared for battle, the portcullis of the castle was lifted up, and he rode forth to meet Sir Tristram; and his young son rode with him as his esquire. Then all the people of the castle gathered together upon the walls to see that battle that was to be, and not one of those several score of folk thought otherwise than that Sir Tristram would certainly be overcome in that encounter.
Sir Nabon rode straight up to Sir Tristram and he said very fiercely, "Sirrah, what is it brings you hither to this land?"
"As to that," said Sir Tristram, "the messenger whom I have sent to you hath, I believe, told you what I come for, and that it is to redeem this island from your possession, and to restore it to the Lady Loise, to whom it belongeth. Likewise that I come to punish you for all the evil you have done."
"And what business is all this of yours?" quoth Sir Nabon, speaking with great fury of voice.
"Messire," quoth Sir Tristram, "know ye not that it is the business of every true knight to rid the world of all such evil monsters as you be?"
"Ha!" quoth Sir Nabon, "that was very well said, for whatever mercy I should have been willing before this to show you hath now been forfeited unto you. For now I shall have no mercy upon you but shall slay you."
"Well," quoth Sir Tristram, "as for that, meseems it will be time enough to offer me mercy after you have overcome me in battle."
Sir Tristram does battle with Sir Nabon.
So thereupon each knight took his place for assault, and when they were in all ways prepared, each set spurs to his horse and dashed the one against the other, with a dreadful, terrible fury of onset. Each smote the other in the very midst of his shield, and at that blow the lance of each was altogether shivered into pieces to the very truncheon thereof. But each knight recovered his horse from the fall and each leaped to earth and drew his sword, and each rushed against the other with such fury that it was as though sparks of pure fire flew out from the oculariums of the helmets. Therewith they met together, and each lashed and smote at the other such fell strokes that the noise thereof might easily have been heard several furlongs away. Now in the beginning of that battle Sir Tristram was at first sore bestead and wist that he had met the biggest knight that ever he had encountered in all of his life, unless it was Sir Launcelot of the Lake, whom he had encountered as aforetold of in this history. So at first he bore back somewhat from the might of the blows of Sir Nabon. For Sir Nabon was so huge of frame and the blows he struck were so heavy that they drove Sir Tristram back as it were in spite of himself.
Sir Tristram slays Sir Nabon.
