The annals of the early years of Edward II. are mainly filled by contemporary chroniclers with details of the miserable strife between the king and his barons on the question of Gaveston's unconstitutional position. But the really important feature of the time was the gradual reconquest of Scotland by Robert Bruce, during the continuance of the domestic strife in England. Edward I. had laid such a firm grip on the northern realm that it required many years to undo his work. A very large proportion of the Scottish nobility regarded Bruce as a usurper who had opened his career with murder and sacrilege, and either openly opposed him or denied him help. His resources were small, and it was only by constant effort, often chequered by failures, that he gradually fought down his local adversaries, and reduced the English garrisons one by one. Dumbarton and Linlithgow were only mastered in 1312. Perth did not finally fall into his hands till 1313; Edinburgh, Roxburgh and Stirling were still holding out in 1314. During all this time the English king only once went north of the Border--in 1311--and then with a very small army, for Lancaster and his friends had refused to join his banner. Yet even under such conditions Bruce had to retire to the mountains, and to allow the invaders to range unopposed through Lothian and Fife, and even beyond the Tay. With ordinary capacity and perseverance Edward II. might have mastered his enemy; indeed the Comyns and Umfravilles and other loyalist barons of Scotland would have carried out the business for him, if only he had given them adequate support. But he spent what small energy he possessed in a wretched strife of chicanery and broken promises with Thomas of Lancaster and his party, dismissing and recalling Gaveston according to the exigencies of the moment, while he let the Scottish war shift for itself. It must be confessed that the conduct of his adversaries was almost as contemptible and unpatriotic. They refused to aid in the war, as if it was the king's private affair and not that of the nation. And repeatedly, when they had Edward at their mercy and might have dictated what terms they pleased to him, they failed to rise to the situation. This was especially the case in 1311, when the king had completely submitted in face of their armed demonstrations. Instead of introducing any general scheme of reform they contented themselves with putting him under the tutelage of twenty-one "lords ordainers," a baronial committee like that which had been appointed by the Provisions of Oxford, fifty years back. Edward was not to levy an army, appoint an official, raise a tax, or quit the realm without their leave. He had also to swear an obedience to a long string of constitutional limitations of his power, and to promise to remove many practical grievances of administration. But there were two great faults in the proceedings of Thomas of Lancaster and his friends.
