The great and rapid increase of power thus attained by Henry Plantagenet necessarily excited the hopes of his mother, and of her adherents in England, who were gratified by the prospect of renewing the contest with Stephen in favour of a young prince whose gallantry and abilities offered the best prospect of success. The English king foresaw the approaching danger, and had no difficulty in perceiving that Henry would command many more supporters in England than would have ranged themselves under the standard of the haughty Matilda. Stephen, therefore, concluded an alliance with Louis of France, as well as with the Count of Blois, and with Geoffrey of Anjou, Henry's younger brother. The two latter willingly took up arms against one who occupied to both of them the position of a successful rival, and they joined the army which the French king marched into Normandy. Henry, however, made a vigorous defence, and having repulsed the attacks of the French with success, he obtained a truce. Meanwhile the Earl of Chester had arrived in the duchy from England, bearing with him a message from a number of chiefs of the Plantagenet party, who invited Henry to take possession of the throne in his own right. The earl declared this to be the unanimous will of the people; and the prince responded to the call, and, without waiting to organise a large force, immediately set sail for England. The army with which he landed numbered about 140 knights, and 3,000 infantry; it was composed, however, of picked men, and was well disciplined. Many of the barons of the kingdom immediately joined his standard, bringing with them considerable reinforcements; and Henry marched his forces to Wallingford for the purpose of giving battle to the king. Meanwhile Stephen had made great exertions to oppose his adversary, and endeavoured, by bribes and other means, to detach the barons from his cause. Some of the latter who had declared for Henry, no sooner heard with what a small force he had ventured into England, than they returned to the side of the king. The war between the opposing factions was carried on in the same manner as before--castles were besieged and taken, and towns carried by assault, plundered, and burnt. The English, driven from their homes, or flying from them in terror, built huts under the walls of the churches, in the hope that the sacredness of the place would protect them from outrage and plunder. No such considerations, however, restrained the belligerents, who expelled the people from their sanctuary, and turned the churches into fortresses. On the steeples, whence the sweet sounds of bells were wont to give the call to prayer, were now placed the frowning engines of war.
