The king proclaimed them traitors.
Strangers sent for.
This answer of the bishop so pricked and wounded the minds of the English Nobilitie, that manie of them (amongst whome the said earle of Penbroke was the chéefe) began an open rebellion, some of them resorting to one place, and some to an other, to gather people for their purpose. The names of such barons as stirred vpon this occasion were these; Richard Marshall earle of Penbroke afore named, Gilbert Basset and his brethren, men of great honor and right hardie capteins: also Richard Sward a warlike personage, trained vp in feats of armes from his youth, with Walter Clifford a worthie knight, and manie others. The king hauing knowledge of their dooings proclaimed them all traitors, confiscated their goods, and sent for a great power of men out of Flanders to serue him in his warre.
Matth. Paris.
The earle of Kent escapeth and taketh sanctuarie.
He is fetcht out.
Whilest king Henrie thus prouided himselfe of an armie, the lords with their capteine Richard Marshall ioined themselues to Leolin prince of Wales, & doubting the comming of the king, spoiled all the marshes next adioining to England, leauing no vittels nor cattell any where about in those parts wherby the kings armie might haue reléefe, and further made all things readie for their owne defense so well as they could deuise. The earle of Kent about the same time, by helpe of two yeomen that attended vpon him, escaped out of the castell of Vées. and tooke sanctuarie in the next church: but when those that had the charge of him and the castell in kéeping, missed him, and heard where he was, they fetcht both him, and the two yeomen that holpe him to make the escape out of the church, and bringing them backe to the castell, imprisoned the earle.
He is restored to sanctuarie.
