When our good lord abbat Edward had been dead well nigh a year, to wit, in the summer season of eleven hundred and forty-two, King Stephen, from great fatigue of body and uneasiness of mind, fell sore sick, and lay for a long while like one that was dying. While this lasted the barons of his party did many evil deeds, there being no authority strong enough to check their lawlessness; and, at the same troublous season, the partisans of Matilda and the foreign mercenaries in her pay did ravage all the western parts; and more robbers came over from Anjou, Normandie, and Picardie, asking no pay, but only free quarters, and the right of plundering the poor English. It was a Benedictine from Rome that had studied medicine in the school of Salerno, that brought a healing potion to the king, and snatched him back to life from the jaws of the grave. So soon as Stephen could mount his war-horse he marched with a great force unto Oxenford, where the countess had fixed her court; and he invested that unhappy city with a firm resolution never to move thence until he had gotten his troublesome rival into his hands. After some fighting, in which many lives were lost by both parties, Stephen burst into the town, and having set fire to a large part thereof, he laid siege unto the castle into which Matilda and her people had retired. Now the castle of Oxenford, standing in the midst of waters, was very strong. From St. Michael's mass well nigh unto Christ's mass, _à festo Michæelis usque ad natali Domini_, did King Stephen persevere in the siege, telling all men that complained of the hard service that he must have the castle, and in it the countess, and that then there would be peace in England.
