The two spots of danger in the English insurrection were the north, where not merely was the king of Scotland prepared for invasion, but the Bishop of Durham, Hugh of Puiset, a connexion of King Stephen, was ready to assist him and had sent also for his nephew, another Hugh of Puiset, Count of Bar, to come to his help with a foreign force; and the east, where Hugh Bigod, the old earl of Norfolk, was again in rebellion and was expecting the landing of the Count of Flanders with an army. It was in the north that the fate of the insurrection was settled and without the aid of the king. The king of Scotland, known in the annals of his country as William the Lion, had begun his invasion in the spring after the expiration of the truce of the previous year, and had raided almost the whole north, capturing some castles and failing to take others such as Bamborough and Carlisle. In the second week of July he attacked Prudhoe castle in southern Northumberland. Encouraged perhaps by the landing of King Henry in England, the local forces of the north now gathered to check the raiding. No barons of high rank were among the leaders. They were all Henry's own new men or the descendants of his grandfather's. Two sheriffs, Robert of Stuteville of Yorkshire and Ranulf Glanvill of Lancashire, probably had most to do with collecting the forces and leading them. At the news of their arrival, William fell back toward the north, dividing up his army and sending detachments off in various directions to plunder the country. The English followed on, and at Alnwick castle surprised the king with only a few knights, his personal guard. Resistance was hopeless, but it was continued in the true fashion of chivalry until all the Scottish force was captured.
