Truce of thirteen years
After this decisive defeat, the Scots plundered the whole country to the north of the Humber, and extended their ravages to Beverley, laying waste the East Riding with fire and sword, and levying from the towns and monasteries, which were rich enough to pay for their escape from plunder, large sums of redemption money.The clergy and inhabitants of Beverley purchased their safety at the rate of four hundred pounds, being six thousand pounds of our present money. Loaded with booty, driving large herds of cattle before them, and rich in multitudes of captives, both of low and high degree, the Scottish army at length returned to their own country .The councils of the King of England continued after this to be weakened by dissension and treachery amongst his nobility. Hartcla, who, for his good service in the destruction of the Lancastrian faction, had been created Earl of Carlisle, soon after, imitating the example of Lancaster, entered into a correspondence with Bruce, and organized an extensive confederacy amongst the northern barons, which had for its object, not only to conclude a truce with the Scots, independent of any communication with the king, but to maintain Robert Bruce and his heirs in the right and possession of the entire kingdom of Scotland. On the discovery of the plot, he suffered the death of a traitor, after being degraded from his new honours, and having his gilt spurs hacked off his heels. Henry de Beaumont, one of the king's councillors, was soon after this disgraced, and committed to the custody of the marshal, on refusing to give his advice in terms of insolence and audacity;so that Edward, unsupported by an army, disgraced by personal flight, and betrayed by some of his most confidential nobility, whilst his kingdom had been incalculably weakened by a long and disastrous war, began to wish seriously for a cessation of hostilities. Nor was Bruce unwilling to entertain pacific overtures. He repelled, indeed, with becoming dignity, a weak attempt to refuse to acknowledge him as the principal leader and party in the truce, and insisted on his recognition as chief of his Scottish subjects; but he consented, by the mediation of his friend, Henry de Sully, to a thirteen-years' truce.
This truce, however, he ratified under the style and title of King of Scotland, and this ratification Edward agreed to accept;thus virtually acknowledging the royal title which he affected to deny. But although desirous of peace, the conduct of the English monarch at this time was marked by dissimulation and bad faith. While apparently anxious for a truce, he employed his ambassadors at the papal court to irritate the Holy Father against Bruce, and to fan the dissensions between them; he summoned an array of the whole military service of England during the negotiations; and he recalled Edward Baliol, the son of the late King of Scots, from his castle in Normandy, to reside at the English court, with the design, as afterwards appeared, of employing him to excite disturbances in Scotland.
