No sooner had the King gained the field of Shrewsbury than he took the most prompt measures to extinguish what remained of the rebellion of the Percies. On the very next day he issued a commission to the Earl of Westmoreland, William Gascoigne, and others, for levying forces to act against the Earl of Northumberland. That nobleman, as we have seen, remained in the north, probably in consequence of a sudden attack of illness, when Hotspur made his ill-fated descent into the south: but the King had good reason to believe that he was still in arms against the crown; and although he despatched that commission of array to the Earl of Westmoreland within only a few hours of the battle, yet (p. 179) he resolved to march forthwith in person,[170] and crush the rebellion by one decisive blow. On Monday the 23rd, the Earl of Worcester was beheaded; and on the same day all his silver vessels, forfeited to the King, were given to the Prince.[171] On the Tuesday the King must have started for the north; for we find two ordinances dated at Stafford, a distance of thirty miles from Shrewsbury, on Wednesday the 25th. Whilst one of these royal mandates savours of severity, the other not only is the message of mercy and forgiveness, but recommends itself to us from the consideration of the person to whom the exercise of the royal clemency was intrusted with unlimited discretion. Henry of Monmouth, perhaps, left Shrewsbury after the battle, and proceeded with his father on his journey northward; but we conclude Stafford to have been, at all events, the furthest point from the Principality to which he accompanied him. Whether the measure of mercy originated with the King or the Prince, certainly both the King believed that his son would gladly execute the commission, and the Prince felt happy in (p. 180) being made the royal representative in the exercise of a monarch's best and holiest prerogative. An ordinance was made by the King at Stafford, investing the Prince of Wales with full powers to pardon the rebels who were in the company of Henry Percy. The Prince probably remained in or near Shrewsbury for the discharge of the duties assigned to him by this commission. The King, having despatched messengers throughout the whole realm announcing Henry Percy's death and the defeat of the rebels, and commanding all ports to be watched that none of the vanquished might escape, proceeded northward. On the 4th of August we find him at Pontefract, from which place he issued an order to the Sheriff[172] of York, which certainly indicates anything rather than a thirst of vengeance on his enemies. It appears that many persons, reckless of justice and confident of impunity, had laid violent hands on the goods of the rebels; and different families had thus been subjected to most grievous spoliation. The King's ordinance conveys a peremptory order to the Sheriff of Yorkshire to interpose his authority, and prevent such acts of violence and wrong, even upon
