Iohn by the grace of God king of England, and lord of Ireland, to all his barons sendeth gréeting. Know yée that we by Gods fauour are in sound and perfect health, and through Gods grace that maruellouslie worketh with vs, on tuesdaie before Lammas daie, we being before the citie of Mauns, were aduertised that our mother was besieged in Mirabeau, and therfore we hasted so fast as we possibly might, so that we came thither on Lammas daie, and there we tooke our nephue Arthur, Hugh le Brun, Andrew de Chauenie, the vicount of Chateau Erald, Raimond de Touars, Sauerie de Mauleon, and Hugh Bangi, and all other enimies of Poictou that were there assembled against vs, to the number of two hundred knights and aboue, so that not one of them escaped. Giue God therefore thanks, and reioise at our good successe.

The French king at the same time lieng in siege before Arques, immediatlie vpon the newes of this ouerthrow, raised from thence, and returned homewards, destroieng all that came in his waie, till he was entred into his owne countrie. It is said that king John caused his nephue Arthur to be brought before him at Falais, and there went about to persuade him all that he could to forsake his fréendship and aliance with the French king, and to leane and sticke to him being his naturall vncle. But Arthur like one that wanted good counsell, and abounding too much in his owne wilfull opinion, made a presumptuous answer, not onelie denieng so to doo, but also commanding king John to restore vnto him the realme of England, with all those other lands and possessions which king Richard had in his hand at the houre of his death. For sith the same apperteined to him by right of inheritance, he assured him, except restitution were made the sooner, he should not long continue quiet. King John being sore mooued with such words thus vttered by his nephue, appointed (as before is said) that he should be straitlie kept in prison, as first in Falais, and after at Roan within the new castell there. Thus by meanes of this good successe, the countries of Poictou, Touraine, and Aniou were recouered.
