The king, when he saw what they demanded (which in effect was a new order in things touching the whole state of the common-wealth) sware in a great furie, that he would neuer condescend vnto those petitions. Whereof when the barons had knowledge, they gat them strait vnto armour, making their assemblie at Stamford in the Easter wéeke, whither they had drawne vnto them almost the whole Nobilitie, and gathered an excéeding great armie. For the commons flocked vnto them from euerie part, bicause the king was generallie hated of the more part of his subiects. [Sidenote: The names of the lords that banded themselues against the king.] It was coniectured that there were in that armie the number of two thousand knights, besides yeomen on horssebacke or demilances (as I may call them) and footemen apparelled in diuerse sorts of armour. The chéefe ringleaders of this power were these, whose names insue: Robert Fitz Walter, Eustace Vescie, Richard Percie, Robert Roos, Peter de Breuse, Nicholas de Stuteuill, Saer earle of Winchester, Robert erle of Clare, Henrie earle of Clare, Richard earle de Bigot, William de Mowbray, William de Cressey, Ralfe Fitz Robert, Robert de Vere, Foulke Fitz Warren, Will.

[Sidenote: An. Reg. 17.] [Sidenote: _Matth. Paris._] [Sidenote: The king sendeth to the lords.] The king as then was at Oxford, who hearing of the assemblie which the barons made, and that they were come to Brakesley, on the mondaie next after the octaues of Easter, he sent vnto them the archbishop of Canturburie, in whom he reposed great confidence, and William Marshall earle of Penbroke, to vnderstand what they meant by that their assembling thus togither. Wherevpon they deliuered to the same messengers a roll conteining the ancient liberties, priuiledges and customs of the realme, signifieng that if the king would not confirme the same, they would not cease to make him warre, till he should satisfie their requests in that behalfe.
