But the two knights instantly disentangled themselves, and fought on foot with shield and sword. So furiously did they hurl themselves at each other that often they fell to the ground. For two hours the duel raged, till their hauberks were tattered and their shields were hacked, while both were sorely bruised and wounded. At length Beaumains thrust Sir Persaunt in the side, and the latter's attack became less eager. Finally Beaumains hit the other so great a stroke that he fell headlong, and instantly Beaumains leaped astride of him and unlashed his helm, as if about to slay him. Then Sir Persaunt yielded him and pleaded for his life, and the lady, who had stood watching the combat, ran forward, placed her hand on Sir Beaumains' sword arm, and cried: 'Of your mercy, Sir Beaumains, yield him his life for my sake.' 'I do it willingly,' cried he, helping the knight to rise, 'for he hath nobly fought and so deserves not to die.' 'Gramercy,' said Sir Persaunt, 'and now I know thou art the strong knight who slew my brothers the Black Knight of the Thorn and the Green Knight of the Wood. And now I will be your man, and five hundred knights of mine shall do your service as and when you will.' And that night they supped bounteously in Sir Persaunt's castle, and the lady besought Beaumains to sit by her at the same table, and all three made merry company. In the morning, after they had heard mass and broken their fast, Beaumains and the lady set out again, and Sir Persaunt went with them to the drawbridge. 'Fair lady,' said he, 'where dost thou lead this valiant knight?' 'Sir,' said the lady, 'he is going to raise the siege which hath been set by the tyrant knight of the Reed Lands.' 'Ah, then he goes to Castle Dangerous, and on the most perilous adventure that any man could take. For they say the Red Knight hath the strength of seven men. And he doth oppress one of the fairest and sweetest ladies in the world. I think you are her sister, Dame Linet?' 'That is my name,' replied the lady, 'and my sister is Dame Lyones.' 'This Red Knight is the most dangerous knight in the world,' said Sir Persaunt to Beaumains, 'and hath besieged that fair lady these two years. Many times he might have forced her for terror to have married him, but he keeps the siege in hopes that Sir Lancelot or even King Arthur would come to rescue the lady. For he hateth all true knights, but those two with most bitterness.' So they parted from Sir Persaunt and rode onwards, and the lady spoke now full friendly to Beaumains. In a little while, when they had passed through a fair forest, they came upon a plain, and in the distance was a high castle with many tents about it, and men passing to and fro between them. And as they rode under some withered trees by the edge of the forest, they saw, hanging by their necks from the bare boughs, many goodly knights in armour, with their shields and swords hung before them.
