Book XIX - Chapter I - How Queen Guenever rode a-Maying with certain knights of the Round Table and clad all in green.
SO it befell in the month of May, Queen Guenever called unto her knights of the Table Round; and she gave them warning that early upon the morrow she would ride a-Maying into woods and fields beside Westminster. And I warn you that there be none of you but that he be well horsed, and that ye all be clothed in green, outher in silk outher in cloth; and I shall bring with me ten ladies, and every knight shall have a lady behind him, and every knight shall have a squire and two yeomen; and I will that ye all be well horsed. So they made them ready in the freshest manner. And these were the names of the knights: Sir Kay le Seneschal, Sir Agravaine, Sir Brandiles, Sir Sagramore le Desirous, Sir Dodinas le Savage, Sir Ozanna le Cure Hardy, Sir Ladinas of the Forest Savage, Sir Persant of Inde, Sir Ironside, that was called the Knight of the Red Launds, and Sir Pelleas, the lover; and these ten knights made them ready in the freshest manner to ride with the queen. And so upon the morn they took their horses with the queen, and rode a-Maying in woods and meadows as it pleased them, in great joy and delights; for the queen had cast to have been again with King Arthur at the furthest by ten of the clock, and so was that time her purpose.
Then there was a knight that hight Meliagrance, and he was son unto King Bagdemagus, and this knight had at that time a castle of the gift of King Arthur within seven mile of Westminster. And this knight, Sir Meliagrance, loved passing well Queen Guenever, and so had he done long and many years. And the book saith he had lain in await for to steal away the queen, but evermore he forbare for because of Sir Launcelot; for in no wise he would meddle with the queen an Sir Launcelot were in her company, outher else an he were near-hand her. And that time was such a custom, the queen rode never without a great fellowship of men of arms about her, and they were many good knights, and the most part were young men that would have worship; and they were called the Queen's Knights, and never in no battle, tournament, nor jousts, they bare none of them no manner of knowledging of their own arms, but plain white shields, and thereby they were called the Queen's Knights. And then when it happed any of them to be of great worship by his noble deeds, then at the next Feast of Pentecost, if there were any slain or dead, as there was none year that there failed but some were dead, then was there chosen in his stead that was dead the most men of worship, that were called the Queen's Knights. And thus they came up all first, or they were renowned men of worship, both Sir Launcelot and all the remnant of them.
But this knight, Sir Meliagrance, had espied the queen well and her purpose, and how Sir Launcelot was not with her, and how she had no men of arms with her but the ten noble knights all arrayed in green for Maying. Then he purveyed him a twenty men of arms and an hundred archers for to destroy the queen and her knights, for he thought that time was best season to take the queen.
