But Sir Tristram was not so soon come into the place, but Sir Gawaine and Sir Galihodin went to King Arthur, and told him: That same green knight in the green harness with the white horse smote us two down, and six of our fellows this same day. Well, said Arthur. And then he called Sir Tristram and asked him what was his name. Sir, said Sir Tristram, ye shall hold me excused as at this time, for ye shall not wit my name. And there Sir Tristram returned and rode his way. I have marvel, said Arthur, that yonder knight will not tell me his name, but go thou, Griflet le Fise de Dieu, and pray him to speak with me betwixt us. Then Sir Griflet rode after him and overtook him, and said him that King Arthur prayed him for to speak with him secretly apart. Upon this covenant, said Sir Tristram, I will speak with him; that I will turn again so that ye will ensure me not to desire to hear my name. I shall undertake, said Sir Griflet, that he will not greatly desire it of you. So they rode together until they came to King Arthur. Fair sir, said King Arthur, what is the cause ye will not tell me your name? Sir, said Sir Tristram, without a cause I will not hide my name. Upon what party will ye hold? said King Arthur. Truly, my lord, said Sir Tristram, I wot not yet on what party I will be on, until I come to the field, and there as my heart giveth me, there will I hold; but to-morrow ye shall see and prove on what party I shall come. And therewithal he returned and went to his pavilions. And upon the morn they armed them all in green, and came into the field; and there young knights began to joust, and did many worshipful deeds. Then spake Gareth unto Sir Tristram, and prayed him to give him leave to break his spear, for him thought shame to bear his spear whole again. When Sir Tristram heard him say so he laughed, and said: I pray you do your best. Then Sir Gareth gat a spear and proffered to joust. That saw a knight that was nephew unto the King of the Hundred Knights; his name was Selises, and a good man of arms. So this knight Selises then dressed him unto Sir Gareth, and they two met together so hard that either smote other down, his horse and all, to the earth, so they were both bruised and hurt; and there they lay till the King with the Hundred Knights halp Selises up, and Sir Tristram and Sir Palomides halp up Gareth again. And so they rode with Sir Gareth unto their pavilions, and then they pulled off his helm.
