It is unnecessary to take seriously the claim of a special right to fill the throne when it was vacant, which the citizens of London advanced for themselves according to a contemporary historian of these events.[29] This is surely less a claim of the citizens than one invented for them by a partisan who wishes to make Stephen's position appear as strong as possible; and no one at the time paid any attention to it. Having secured the support of London, after what can have been only a few days' stay, Stephen went immediately to Winchester. Before he could really believe himself king, he had to secure the royal treasures and more support than he had yet gained. Stephen's own brother Henry, who owed his promotion in the Church, as Stephen did his in the State, to his uncle, was at this time Bishop of Winchester; and it was due to him, as a contemporary declares, that the plan of Stephen succeeded, and the real decision of the question was made, not at London, but at Winchester.[30] Henry went out with the citizens of Winchester to meet his brother on his approach, and he was welcomed as he had been at London. Present there or coming in soon after, were the Archbishop William of Canterbury, Roger, Bishop of Salisbury, the head of King Henry's administrative system, and seemingly a few, but not many, barons. On the question of making Stephen king, the good, though not strong, Archbishop of Canterbury, was greatly troubled by the oath which had been sworn in the interest of Matilda. "There are not enough of us here," his words seem to mean, "to decide upon so important a step as recognizing this man as king, when we are bound by oath to recognize another."[31] Though our evidence is derived from clerical writers, who might exaggerate the importance of the point, it seems clear from a number of reasons that this oath to Matilda was really the greatest difficulty in Stephen's way. That it troubled the conscience of the lay world very much does not appear, nor that it was regarded either in Normandy or England as settling the succession. If the Norman barons had been bound by this oath as well as the English, as is altogether probable, they certainly acted as if they considered the field clear for other candidates. But it is evident that the oath was the first and greatest difficulty to be overcome in securing for Stephen the support of the Church, and this was indispensable to his success. The active condemnation of the breaking of this oath survived for a long time in the Church, and with characteristic medieval logic the fate of those few who violated their oaths and met some evil end was pointed to as a direct vengeance of God, while that of the fortunate majority of the faithless is passed over in silence, including the chief traitor Hugh Bigod, who, as Robert of Gloucester afterwards declared, had twice sworn falsely, and made of perjury an elegant accomplishment.[32]
