The legate, who had probably never been sincere in his compliance with Matilda’s government, availed himself of the ill humor excited by this imperious conduct, and secretly instigated the Londoners to a revolt. A conspiracy was entered into to seize the person of the empress, and she saved herself from the danger by a precipitate retreat. She fled to Oxford: soon after she went to Winchester, whither the legate, desirous to save appearances, and watching the opportunity to ruin her cause, had retired. But having assembled all his retainers, he openly joined his force to that of the Londoners, and to Stephen’s mercenary troops, who had not yet evacuated the kingdom; and he besieged Matilda in Winchester. The princess, being hard pressed by famine, made her escape; but in the flight, Earl Robert, her brother, fell into the hands of the enemy. This nobleman, though a subject, was as much the life and soul of his own party, as Stephen was of the other: and the empress, sensible of his merit and importance, consented to exchange the prisoners on equal terms. The civil war was again kindled with greater fury than ever. {1142.} Earl Robert, finding the successes on both sides nearly balanced, went over to Normandy, which, during Stephen’s captivity, had submitted to the earl of Anjou; and he persuaded Geoffrey to allow his eldest son, Henry, a young prince of great hopes, to take a journey into England, and appear at the head of his partisans. {1143.} This expedient, however, produced nothing decisive. Stephen took Oxford after a long siege: he was defeated by Earl Robert at Wilton; and the empress, though of a masculine spirit, yet being harassed with a variety of good and bad fortune, and alarmed with continual dangers to her person and family, at last retired into Normandy, {1146.} whither she had sent her son some time before. The death of her brother, which happened nearly about the same time, would have proved fatal to her interests, hail not some incidents occurred which checked the course of Stephen’s prosperity. This prince, finding that the castles built by the noblemen of his own party encouraged the spirit of independence, and were little less dangerous than those which remained in the hands of the enemy, endeavored to extort from them a surrender of those fortresses and he alienated the affections of many of them by this equitable demand. The artillery, also, of the church, which his brother had brought over to his side, had, after some interval, joined the other party. Eugenius III. had mounted the papal throne; the bishop of Winchester was deprived of the legantine commission, which was conferred on Theobald, archbishop of Canterbury, the enemy and rival of the former legate. That pontiff, also, having summoned a general council at Rheims, in Champagne, instead of allowing the church of England, as had been usual, to elect its own deputies, nominated five English bishops to represent that church, and
