The army thus raised by Henry was composed, for the most part, of the infantry of the Low Countries, who were already distinguished for their stubborn resolution and gallantry in combat. The king was accompanied by Thomas Becket, who had lately been made Chancellor of England, and also by Malcolm, King of Scotland, and Raymond, King of Aragon, with whom Henry had formed an alliance. The town of Cahors was quickly reduced, and the English army marched upon Toulouse, which was defended by the citizens under Raymond, in conjunction with a small body of troops which the King of France had marched to their assistance. Becket, who, although in holy orders, marched in warlike equipments at the head of 700 knights and men-at-arms, displayed great energy in the field. He advised the king to take advantage of the weakness of the garrison, to make an immediate attack upon the place; but Henry, whose audacity was tempered by profound calculation, hesitated to commit an act in direct defiance of those feudal laws in whose support he had himself the strongest interest. As Count of Anjou, Henry was the hereditary Seneschal of France, and he asserted that he could not make an attack upon the troops of his feudal suzerain. A second French army advancing to the defence of Toulouse, Henry raised the siege, and committing the command of his forces to Becket, returned with a small body of troops into Normandy. Thither the chancellor soon afterwards followed him, having taken possession of a few castles on the banks of the river Garonne. A campaign ensued, which lasted for a few months, on the frontiers of Normandy; and was brought to a conclusion in 1160 by a treaty, according to the terms of which the eldest son of Henry did homage to Louis for the dukedom of Normandy.
