In the meanwhile the injured Matilda appealed to Rome, but only with the result that her rival received formal recognition from the Pope. Three years later (1139) she landed in England accompanied by her brother, the Earl of Gloucester. She soon obtained a following, more especially in the west; and Winchester—the seat of the royal residence of the queens of England since the time when Ethelred presented the city as a "morning gift" to his consort at their marriage—became her headquarters and rallying point for her supporters, whilst London served in the same way for Stephen. (M76) After nine months of sieges and counter sieges, marches and counter marches, in which neither party could claim any decided success, Stephen, as was his wont, withdrew to London and shut himself up in the Tower, with only a single bishop, and he a foreigner, in his train. Whilst safe behind the walls of that stronghold, negotiations were opened between him and the empress for a peaceful settlement of their respective claims (May, 1140), Henry of Winchester acting as intermediary between the rival parties.(113) The negotiations ended without effecting the desired result. (M77) Matters assumed an entirely different aspect when Stephen was made prisoner at Lincoln in the following year (2nd Feb., 1141). Henry of Winchester forsook his rôle of arbitrator, and entered into a formal compact with the empress who arrived before Winchester with the laurels of her recent success yet fresh, agreeing to receive her as "Lady of England," (_Domina Angliæ_) and promising her the allegiance of himself and his followers so long as she would keep her oath and allow him a free hand in ecclesiastical matters.(114) (M78) This compact was entered into on the 2nd March, and on the following day the empress was received with solemn pomp into Winchester Cathedral. It remained for the compact to be ratified. For this purpose an ecclesiastical synod was summoned to sit at Winchester on the 7th April. The day was spent by the legate holding informal communications with the bishops, abbots, and archdeacons who were in attendance, and who then for the first time in England’s history claimed the right not only of consecration, but of election of the sovereign.(115)
