But within a while after there grew much difference[268] betwixt him and the king his brother, touching a certain lordship given to Waleran Teutonicus (id est, Ties) by King John, which he alleged[268] to be parcel of the Earldom of Cornwall, and caused possession to be taken of it for himself; whereupon, Waleran making a complaint, the king first wrote to him about it, and then sent for him, commanding the render thereof, which he refused to do, challenging the judgment of his peers as to matter of right. Whereat the king took such offence that he required him forthwith to do it, or depart the realm; unto which he answered, that he would not deliver up the land, nor, without the sentence of his peers, go out of the kingdom; and in great discontent departing went[268] to his own house; which breach betwixt the king and him caused Hubert de Burgh (then justice of England, and in chief power at court) to advise the king to surprise him in his bed the next night following, lest he should raise a disturbance in the realm; but being privily advertised of that design, he fled immediately away, making no stop till he got[269] to Reading; and thence hasting to Marlborough, there found his trusty friend William Mareschal, Earl of Pembroke, unto whom having made relation of what had passed, they took their course to the Earl of Chester; and being thus got together, through the power and interest of their friends raised a potent army, making their rendezvous at Stanford, whence they sent a minatory message to the king, but imputing all the fault to Hubert de Burgh, requiring a confirmation of that charter of the forest which had been cancelled at Oxford. The king, therefore, discerning this cloud, appointed a meeting at Northampton upon the third of the nones of August next following, assuring them that he would there do full right unto all; where meeting accordingly, for their better satisfaction (amongst other his condescensions) he gave this Earl Richard his mother’s dowry, with all the lands in England which did appertain to the Earl of Britanny, as also those which belonged to the Earl of Bolein, then deceased[270]; whereupon, he had livery[271] of the whole county of Rutland. And in 15 Henry III. obtained another grant[272] of the inheritance of the honour of Walingford, with the castle and all its appurtenances, as also the manor of Watlington, to hold by the service of three knights’ fees; likewise, of all the lands in England[272] which Queen Isabell (the king’s mother) held in dower, and of those which belonged to Robert de Drewes, and to the Duke of Lorrain (at that time seised into the king’s hands), to hold until such time as the king should restore them.
