It was the dangerous aspect of affairs in Scotland that forced the king to submit so easily to the demands of his barons. Already, in the spring of 1297, Wallace, without any countenance from the Scottish nobility, had commenced a guerilla warfare, and his handful of desperate men soon increased into an army, which completely defeated Earl Warenne and Cressingham at Cambuskenneth (Stirling Bridge), in September, 1297, and ravaged England, with the most atrocious cruelties, from Newcastle to Carlisle. Edward's expedition to Flanders had been a failure, but he hastened to conclude a truce, so as to find time to chastise the Scots, cementing it by his betrothal to Philip's sister Margaret. The good Queen Eleanor had been already dead nine years.
Meantime, Wallace's success had merely earned him the bitter jealousy of the Scottish nobles, and his power was finally broken in the disastrous defeat by Edward's army at Falkirk in July, 1298. The king had two of his ribs broken by a kick from his horse on the morning of the battle, but rode throughout the day as if unhurt. The struggle lingered on some years under various leaders, as Edward found his energy paralyzed the while by the intrigues of Philip, and the constitutional struggle with his barons. Pope Boniface, in 1301, put forth a claim to the over-lordship of Scotland, which was repudiated by the whole body of the estates at Lincoln. It was not till the June of 1303 that the king was able to resume his conquest. Accompanied by a fleet carrying his supplies, he penetrated again into the far North, tarried a while in Dunfermline, and settled the kingdom after the reduction of Stirling, the last place of strength that held out. In 1305 Wallace was betrayed into his hands, sent to London, and cruelly executed as a traitor. The fate of this noble-hearted patriot is a fatal blot upon his conqueror's memory, but it should not be forgotten that Edward was profoundly convinced of the legality of his own claims over Scotland, and that Wallace to him was merely a pestilent rebel, who had earned his doom by treason to his lord and by the cruelties he had inflicted upon Englishmen. The same year the king prepared a new constitution for the conquered kingdom, divided it into sheriffdoms like the English counties, and made arrangements for the representation of the Scots in the English parliament--a measure which, had it been successful, might have anticipated by four centuries the benefits of the union.
