After his departure ouer, William earle of Salisburie, William earle of Arundell, William earle Warren, and diuerse other reuolted to king Henrie. Moreouer, William Marshall earle of Penbroke so trauelled with his son William Marshall the yoonger, that he likewise came to take part with the yoong king: whereby the side of Lewes and his Frenchmen was sore weakened, and their harts no lesse appalled for the sequele of their affaires. Lewes returned yet into England before the truce was expired. The lords that held on the kings part in the absence of Lewes, were not forgetfull to vse opportunitie of time: for beside that they had procured no small number of those that before time held with Lewes to reuolt from him to the kings side, they at one selfe time besieged diuerse castels, and recouered them out of their aduersaries hands, as Marleborough, Farneham, Winchester, Cicester, and certeine other, which they ouerthrew and raced, bicause they should not be taken and kept againe by the enimie. For ye must vnderstand, that the going ouer of Lewes now at that time, when it stood him most vpon to haue béene present here in that troublesome season (which he ought to haue regarded with singular circumspection, and warilie to haue watched, for Virtus est, vbi occasio admonet, dispicere) brought no small hinderance to the whole state of all his businesse, in so much that he was neuer so highlie regarded afterwards among the Englishmen as before.

Henrie defended the place right manfully, and doubting to be in distres by long siege, sent with all spéed to the earle of Winchester, Saer de Quincie as then being at London with the Frenchmen, requiring him to send some succour to remoue the siege. Herevpon the earle of Winchester, to whom that castell belonged, required Lewes that some conuenient power might be sent, whereby the siege might be remooued. Wherefore vpon councell taken with deliberate aduise, it was ordeined that an armie should be sent thither with all spéed, not onlie to raise the siege, but also to subdue that countrie vnto the obedience of Lewes. Herwith there went out of London 600 knights, and with them aboue twentie thousand men in armour, gréedie (as it séemed) to haue the spoile of other mens goods.
