It is natural to suppose that the many barons who now declared against the king, and fortified their castles, were influenced by a knowledge of Robert's action, or at least by a knowledge that it was coming. No one of these was of the rank of earl. William Peverel, Ralph Lovel, and Robert of Lincoln, William Fitz John, William of Mohun, Ralph Paganel, and William Fitz Alan, are mentioned by name as holding castles against the king, besides a son of Robert's and Geoffrey Talbot who were at Bristol, and Walkelin Maminot who held Dover. The movement was confined to the southwest, but as a beginning it was not to be neglected. Stephen acted with energy. He seized Robert's lands and destroyed his castles wherever he could get at them. A large military force was summoned. The queen was sent to besiege Dover castle, and she drew from her county of Boulogne a number of ships sufficient to keep up the blockade of the harbour. The king himself advanced from London, where he had apparently gone from Hereford to collect his army and arrange his plans, against Bristol which was the headquarters of Robert's party. Bristol was strong by nature, protected by two rivers and open to the sea, and it had been strongly fortified and prepared for resistance. There collected the main force of the rebels, vassals of Robert, or men who, like Geoffrey Talbot, had been dispossessed by Stephen, and many mercenaries and adventurers. Their resources were evidently much less than their numbers, and probably to supply their needs as well as to weaken their enemies they began the ravaging of the country and those cruel barbarities quickly imitated by the other side, and by many barons who rejoiced in the dissolution of public authority--the plundering of the weak by all parties--from which England suffered so much during the war. The lands of the king and of his supporters were systematically laid waste. Cattle were driven off, movable property carried away, and men subjected to ingenious tortures to force them to give up the valuables they had concealed. Robert's son, Philip Gai, acquired the reputation of a skilful inventor of new cruelties. These plundering raids were carried to a distance from the city, and men of wealth were decoyed or kidnapped into Bristol and forced to give up their property. The one attempt of these marauders which was more of the nature of regular warfare, before the king's approach, illustrates their methods as well. Geoffrey Talbot led an attack on Bath, hoping to capture the city, but was himself taken and held a prisoner. On the news of this a plot was formed in Bristol for his release. A party was sent to Bath, who besought the bishop to come out and negotiate with them, promising under oath his safe return; but when he complied they seized him and threatened to hang him unless Geoffrey were released. To this the bishop, in terror of his life, at last agreed. Stephen shortly after came to Bath on his march against
