After the battle the Welsh behaved with the greatest savagery; killing all the wounded, stripping the fallen, and horribly mutilating their bodies. The news created great excitement at Alnwick and, had not the situation in the north been critical, Percy would have gathered his forces and marched, with all speed, to avenge the defeat and capture of his brother-in-law. The Earl of Dunbar, with many of the tenants of his former estates, and numbers of the English borderers, had entered Scotland and carried out considerable raids. In revenge for this, Douglas despatched Thomas Halliburton and Patrick Hepburn, each with a considerable force, to invade Northumberland. Halliburton ravaged the country as far as Bamborough, collected great spoils, and returned with them. Hepburn, who had a still larger force, penetrated farther into England, carried his ravages to within a few miles of Alnwick; and then retired north, with an enormous amount of booty. When, however, he had crossed the border into the country known as the Merse, north of Berwick, the Earl of Dunbar fell upon him at West Nesbit, and completely defeated him. Hepburn himself, with a large number of his men, fell in the battle; and many important prisoners were captured. This battle was fought on the same day that Glendower defeated Mortimer. The victory caused great exultation on the border; but Alwyn said to his nephew: "Although this is good, as far as it goes, Oswald, you may be sure that Douglas will not brook this disaster with patience, but will gather the Scottish forces; and we may expect him, ere long, at the head of twenty thousand men, and we shall have a fight as stiff as that of Otterburn. We shall have Northumberland ablaze, and you will see that the earl and Hotspur will soon be preparing to meet the storm. "These last forays took them by surprise; and, as lords of the marches, they have suffered serious humiliation, for this victory was not theirs, but the work of Dunbar; and had he not intercepted the Scots, on their own side of the border, they would have returned, scatheless, with the spoils of our northern districts. This disgrace will spur them on to make great efforts, and these will be needed, or we shall see Northumberland, Cumberland, and Durham in flames." Alwyn was not mistaken. Messengers were sent off to all those holding knights' feus, throughout the county, bidding them to prepare to answer to the Percy's call; and to hold themselves, and their tenants, in readiness to march to any point fixed upon for a general rendezvous. They were to warn all the countryside that, directly news arrived that the Scots were in motion, they were to drive their cattle and horses to the nearest fortified town, or to take them to hiding places among the hills. Everything of value was to be taken away, or hidden, so that the enemy should find but empty houses. Oswald rode to Yardhope, with the message to his father.
