Between this northern belt of rebel strongholds, however, and the southern one which stretched from Chester to Axholm, there lay along the river-valleys of Cumberland and Northumberland a cluster of royal castles. Nicolas de Stuteville held Liddell, on the river of the same name. Burgh[751] stood on the Solway Firth, nearly opposite Annan; the whole valley of the Eden was guarded by Carlisle, whose castellan was Richard de Vaux,[752] and Appleby, which like Burgh was held by Robert de Stuteville for the king.[753] The course of the Tyne was commanded by Wark, under Roger de Stuteville,[754] Prudhoe, under Odelin de Umfraville,[755] and by the great royal fortress of Newcastle, in charge of Roger Fitz-Richard;[756] further north, between the valleys of the Wansbeck and the Coquet, stood Harbottle, also held by Odelin, with Roger Fitz-Richard’s Warkworth[757] and William de Vesci’s Alnwick[758] at the mouths of the Coquet and the Alne. This chain of defences William of Scotland, when at the expiration of the truce he again marched into England, at once set himself to break. While his brother David went to join the rebel garrison of Leicester,[759] he himself began by laying siege to Wark. This fortress, held in the king’s name by Roger de Stuteville--apparently a brother of the sheriff of Yorkshire--occupied a strong position in the upper valley of the Tyne, on the site of an earlier fortress which under the name of Carham had played a considerable part in the Scottish wars of Stephen’s time, and had been finally taken and razed by William’s grandfather King David in 1138.[760] William himself had already in the preceding autumn besieged Wark without success;[761] he prospered no better this time, and presently removed his forces to Carlisle,[762] where he had also sustained a like repulse six months before.[763] Carlisle, as well as Wark, was in truth almost impregnable except by starvation; and William, while blockading it closely, detached a part of his host for a series of expeditions against the lesser fortresses, Liddell, Burgh, Appleby, Harbottle and Warkworth, all of which fell into his hands.[764] His brother’s arrival at Leicester, meanwhile, seemed to have revived the energies of its garrison; under the command of Earl Robert of Ferrers they sallied forth very early one morning, surprised and burned the town of Nottingham, made a great slaughter of its citizens, and went home laden with plunder and prisoners.[765] [751] _Gesta Hen._ (Stubbs), vol. i. p. 65.
