To assist him in this war, he summoned Baliol, and others of the most powerful of the Scottish nobles, to attend him in person with their armed vassals; but his insolent and overbearing conduct had entirely disgusted the Scots. They treated his summons with scorn; and, instead of arming their vassals for his assistance, they assembled a parliament at Scone. Its first step was, under the pretence of diminishing the public charges, to dismiss all Englishmen from Baliol's court; and having thus got rid of such troublesome spies upon their measures, they engaged in a treaty of alliance with France, and determined upon war with Edward. Many estates in Scotland were at this time held by English barons, and many also of the most powerful of the Scottish nobility possessed lands in England. Anxious for a general union against the common enemy, the Scottish estates in the hands of English barons were forfeited, and their proprietors banished; while those Scottish nobles who remained faithful to Edward had their lands seized and forfeited.
In this way Robert Bruce lost his rich lordship of Annandale. It was given to John Comyn earl of Buchan, who instantly assumed the rights of a proprietor, and took possession of its castle of Lochmaben —an injury which, in that fierce age, could never be forgotten.
Edward, although enraged at the conduct of the Scottish parliament, and meditating a deep revenge, was at this time harrassed by a rebellion of the Welsh, and a war with France. Dissimulation and policy were the weapons to which he had recourse, whilst he employed the interval which he gained in sowing dissension among the Scottish nobles, and collecting an army for the punishment of their rebellion. To Bruce, the son of the competitor for the crown, whose mind was irritated by the recent forfeiture of his estates, he affected uncommon friendship; regretted his decision in favour of the now rebellious Baliol; declared his determination to place him on the throne, of which the present king had shown himself unworthy; and directed him to inform his numerous and powerful friends in Scotland of this resolution.
