However averse he might have been to risk the chances of hostilities, William was evidently a very cool friend to England during the next five years, eagerly testifying his devotion to the papal see when the interdict was levelled against John, and receiving in return from Pope Innocent a bull, or rescript, fully confirming every liberty and immunity that had at any time been conferred upon the king, church, or kingdom of Scotland, by the head of the Roman Church.[489] He appears, also, to have set on foot a negotiation for procuring a foreign alliance for one of his children;[490] [Sidenote: A. D. 1209.] but the fears of John were by this time aroused, and he marched with an immense army to the north, in the determination of calling William to account for destroying his castle at Tweedmouth, for aiming at an alliance with his open enemies, and for negotiating the intended marriage without consulting the suzerain of whom he held his English fiefs. To guard against the chances of invasion, William occupied a strong position in the neighbourhood of Roxburgh, where he gave audience to the envoys of John, who, upon reaching Norham, dispatched a safe conduct to the Scottish king, with a requisition to meet him at Newcastle; but three days after his arrival at the place of meeting, and before their conference had resulted in any satisfactory conclusion, it was unexpectedly interrupted by the sudden illness of the Scottish king, and all further proceedings were broken off after a temporary truce had been arranged.[491] The return of health revived the reluctance of William to yield to the demands of John, and, after ascertaining the sentiments of his baronage and clergy in a council held at Stirling, he dispatched the bishops of St. Andrews and Glasgow, with William Comyn and Philip de Valoniis, the Justiciary and Chamberlain of Scotland, charged with so decided an answer to the English king, that John’s fury was aroused to the utmost pitch, and he issued immediate orders for the assemblage of his army, and the reconstruction of the castle at Tweedmouth. William, upon learning the result of his embassy, hurried from Forfar towards the Lothians, deputing the bishop of St. Andrews to convey a qualified refusal to the incensed John. Arrived at Edinburgh, the king was met by Sayer de Quinci, Earl of Winchester, and Robert de Ros, who had already reached the future Scottish capital, and dwelt upon the wrath of their royal master, and the magnitude of the army with which he was hurrying, by forced marches, to the north.[492]
