The lists for this decision of truth and right were appointed at Coventry before the king: all the nobility of England banded into parties, and adhered either to the one duke or the other: the whole nation was held in suspense with regard to the event; but when the two champions appeared in the field accoutred for the combat, the king interposed, to prevent both the present effusion of such noble blood, and the future consequences of the quarrel.

By the advice and authority of the parliamentary commissioners, he stopped the duel; and to show his impartiality, he ordered, by the same authority both the combatants to leave the kingdom;[*] assigning one country for the place of Norfolk's exile, which he declared perpetual, another for that of Hereford, which he limited to ten years.
