Assisted by Berenger, count of Barcelona, and Trincaval, count of Nismes, whom he had gained to his party, he invaded the county of Toulouse; and after taking Verdun, Castlenau, and other places, he besieged the capital of the province, and was likely to prevail in the enterprise; when Lewis, advancing before the arrival of his main body, threw himself into the place with a small reenforcement. Henry was urged by some of his ministers to prosecute the siege, to take Lewis prisoner, and to impose his own terms in the pacification; but he either thought it so much his interest to maintain the feudal principles, by which his foreign dominions were secured, or bore so much respect to his superior lord, that he declared he would not attack a place defended by him in person; and he immediately raised the siege. He marched into Normandy to protect that province against an incursion which the count of Dreux, instigated by King Lewis, his brother, had made upon it. War was now openly carried on between the two monarchs, but produced no memorable event: it soon ended in a cessation of arms, and that followed by a peace, which was not, however, attended with any confidence or good correspondence between those rival princes. {1160.} The fortress of Gisors, being part of the dowry stipulated to Margaret of France, had been consigned by agreement to the knights templars, on condition that it should be delivered into Henry’s hands after the celebration of the nuptials. The king, that he might have a pretence for immediately demanding the place, ordered the marriage to be solemnized between the prince and princess, though both infants; and he engaged the grand master of the templars, by large presents, as was generally suspected, to put him in possession of Gisors.[*] {1161.} Lewis, resenting this fraudulent conduct, banished the templars, and would have made war upon the king of England, had it not been for the mediation and authority of Pope Alexander III., who had been chased from Rome by the antipope, Victor IV., and resided at that time in France. [* Since the first publication of this History, Lord Lyttleton has published a copy of the treaty between Henry and Lewis, by which it appears, if there was no secret article, that Henry was not guilty of any fraud in this transaction, observe, that the two kings had the year before, met the pope at the castle of Torci on the Loir; and they gave him such marks of respect, that both dismounted to receive him, and holding each of them one of the reins of his bridle, walked on foot by his side, and conducted him in that submissive manner into the castle: “a spectacle,” cries Baronius in an ecstasy, “to God, angels, and men; and such as had never before been exhibited to the world!”]
