In 1174 young Henry sought refuge with Louis VII. at St. Denis. On the news of this escape being brought to the old king, he displayed all the energy of former years, and, mounting on horseback, he proceeded along the frontier of Normandy, inspecting the defences, and preparing against attacks. Messengers, with a similar object, were also dispatched to the captains of the royal garrisons in Anjou, Aquitaine, and Brittany. Meanwhile the two princes, Richard and Geoffrey, followed their brother to the French court. Henry now sent envoys to the French court, demanding his son, and also requiring to know the intentions of the King of France. The ambassadors were received in full court, in the presence of young Henry and his brothers. When, according to the usual form, they commenced their message by enumerating the titles of their royal master, they were interrupted by Louis, who declared that there was but one King of England--namely, the young prince now standing before them. Young Henry was recognised by a general assembly of the barons and bishops of France as having the only lawful right to the English throne. Louis VII. made oath to this effect, and after him the brothers of Henry and the barons of the kingdom. A great seal was made with the arms of the King of England, in order that Henry might affix that sign of royalty to his documents of state. His first acts were grants of land and estates to the barons of France and the enemies of his father who were willing to join the confederacy. Among these were William, King of Scotland, who was to receive the territories of Northumberland and Cumberland, conquered by his predecessors; Philip, Count of Flanders, to whom was promised the earldom of Kent, and the castles of Dover and Rochester; and the Count of Blois, who was to have Amboise, Château-Renault, and five hundred pounds of silver from the revenues of Anjou. Other donations were made of a similar kind, and the young king sent messengers to Rome to obtain the sanction of the Pope. Meanwhile the cause of the rebellious son was embraced by many powerful chiefs, even among the vassals of the English king. Not a few recalled former acts of arrogance or oppression for which the present occasion offered the prospect of vengeance; others, who were young in arms, and of turbulent and adventurous spirit, were easily induced to take up arms in favour of the gay young prince. In England the Earls of Leicester and Chester were the principal supporters of his cause.
