In the first month of 1306, however, the weary Scottish war broke out again, with the appearance of a new insurgent chief. Robert Bruce, earl of Carrick, grandson of the claimant to the throne of 1292, had hitherto pursued a shifty policy, wavering between submission and opposition to the English invader. He had been in arms more than once, but had finally adhered to the pacification of 1304, and was now entirely trusted by the king. But he was secretly plotting rebellion, disgusted (as it would seem) that Edward had not transferred the crown of Scotland to the line of Bruce when the house of Baliol was found wanting. Though he found himself certain of a considerable amount of support, he yet could see that there would be no general rising in his favour, for many of the magnates refused to help in making king a baron whom they regarded as no more important than one of themselves. But the insurrection was precipitated by an unpremeditated outrage. Bruce was conferring at Dumfries with John Comyn, the late regent, whom he was endeavouring to tempt into his plots, on the 10th of January 1306. An angry altercation followed, for Comyn would have nothing to do with the scheme, and Bruce and his followers finally slew him before the altar of a church into which he had fled. After this crime, which combined the disgrace of sacrilege with that of murder under tryst, Bruce was forced to take arms at once, though his preparations were incomplete. He raised his banner, and was hastily crowned at Scone on the 25th of March; by that time the rising had burst out in many shires of Scotland, but it was neither unanimous nor complete. Edward by no means despaired of crushing it, and had raised a large army, when he was smitten with an illness which prevented him from crossing the border. But his troops, under Aymer de Valence, earl of Pembroke, pressed north, and surprised and routed Bruce at Methven near Perth. The pretender's brother Nigel and many of his chief supporters were taken prisoners, and he himself escaped with a handful of followers and took refuge in the Western islands. Edward ordered young Nigel Bruce and many other captives to be executed; for he was provoked to great wrath by the rebellion of a magnate who had given him every assurance of loyalty. He intended to follow de Valence to Scotland, and to complete the suppression of the rising in person. But this proved beyond his strength; he struggled as far as the border in July, but could not shake off his disease, and was forced to linger, a broken invalid, in the neighbourhood of Carlisle for many months. Meanwhile his lieutenants failed to follow up with energy the victory gained at Methven, and in the next spring Bruce reappeared in the Lowlands, gathered new levies, and inflicted a defeat on de Valence at Loudoun Hill. Roused to anger King Edward rose from his bed, mounted his horse, and started for Scotland. But after struggling on for a few miles
