Here is an extract from it:
Then Sir Brian de les Isles and Grummore Grummorsum, knights of the castle, encountered with Sir Aglovale and Sir Tor, and Sir Tor smote down Sir Grummore Grummorsum to the earth. Then came Sir Carados of the dolorous tower, and Sir Turquine, knights of the castle, and there encountered with them Sir Percivale de Galis and Sir Lamorak de Galis, that were two brethren, and there encountered Sir Percivale with Sir Carados, and either brake their spears unto their hands, and then Sir Turquine with Sir Lamorak, and either of them smote down other, horse and all, to the earth, and either parties rescued other and horsed them again. And Sir Arnold, and Sir Gauter, knights of the castle, encountered with Sir Brandiles and Sir Kay, and these four knights encountered mightily, and brake their spears to their hands. Then came Sir Pertolope from the castle, and there encountered with him Sir Lionel, and there Sir Pertolope the green knight smote down Sir Lionel, brother to Sir Launcelot. All this was marked by noble heralds, who bare him best, and their names. Then Sir Bleobaris brake his spear upon Sir Gareth, but of that stroke Sir Bleobaris fell to the earth. When Sir Galihodin saw that, he bad Sir Gareth keep him, and Sir Gareth smote him to the earth. Then Sir Galihud gat a spear to avenge his brother, and in the same wise Sir Gareth served him, and Sir Dinadan and his brother La Cote Male Taile, and Sir Sagramore le Disirous, and Sir Dodinas le Savage; all these he bare down with one spear. When King Aswisance of Ireland saw Sir Gareth fare so he marvelled what he might be, that one time seemed green, and another time, at his again coming, he seemed blue. And thus at every course that he rode to and fro he changed his color, so that there might neither king nor knight have ready cognizance of him. Then Sir Agwisance the King of Ireland encountered with Sir Gareth, and there Sir Gareth smote him from his horse, saddle and all. And then came King Carados of Scotland, and Sir Gareth smote him down horse and man. And in the same wise he served King Uriens of the land of Gore. And then there came in Six Bagdemagus, and Sir Gareth smote him down horse and man to the earth. And Bagdemagus's son Meliganus brake a spear upon Sir Gareth mightily and knightly. And then Sir Galahault the noble prince cried on high, Knight with the many colors, well hast thou justed; now make thee ready that I may just with thee. Sir Gareth heard him, and he gat a great spear, and so they encountered together, and there the prince brake his spear; but Sir Gareth smote him upon the left side of the helm, that he reeled here and there, and he had fallen down had not his men recovered him. Truly, said King Arthur, that knight with the many colors is a good knight. Wherefore the king called unto him Sir Launcelot, and prayed him to encounter with that knight. Sir, said Launcelot, I may as well find in my heart for to forbear him at this time, for he hath had travail enough this day, and when a good knight doth so well upon some day, it is no good knight's part to let him of his worship, and, namely, when he seeth a knight hath done so great labour; for peradventure, said Sir Launcelot, his quarrel is here this day, and peradventure he is best beloved with this lady of all that be here, for I see well he paineth himself and enforceth him to do great deeds, and therefore, said Sir Launcelot, as for me, this day he shall have the honour; though it lay in my power to put him from it, I would not.
There was an unpleasant little episode that day, which for reasons of state I struck out of my priest's report. You will have noticed that Garry was doing some great fighting in the engagement. When I say Garry I mean Sir Gareth. Garry was my private pet name for him; it suggests that I had a deep affection for him, and that was the case.
