Though the Scottish expedition to Ireland had been beaten off, this was not in the least to be ascribed to the credit of Lancaster, who was showing the grossest incompetence as an administrator. He could neither protect the Border, nor even prevent private civil wars from breaking out, not only on the Welsh marches (where they had always been common), but even in the heart of England. The most extraordinary symptom of the time was a civic revolt at Bristol (1316), where the townsfolk expelled the royal judges, and actually stood a siege before they would submit. Such revolts of great towns were normal in Germany or Italy, but almost unknown on this side of the Channel. All this unrest might well be ascribed to Lancaster's want of ability, but he had also to bear--with less justice--the discontent caused by two years of famine and pestilence. In August 1318 he was removed from power by a league formed by Pembroke, Warenne, Arundel and others of the lords ordainers, who put a new council in power, and showed themselves somewhat less hostile to the king than Earl Thomas had been. Edward was allowed to raise an army for the siege of Berwick, and was lying before its walls, when the Scots, turning his flank, made a fierce foray into Yorkshire, and routed the shire-levy under Archbishop Melton at the battle of Myton. This so disheartened the king and the council that controlled him that they concluded a two years truce with Robert of Scotland, thus for the first time acknowledging him as a regular enemy and no mere rebel (1319).
