Hugh Bigod, the Earl of Norfolk, whose allegiance had ever sat lightly upon him, appears to have eventually become his ally,[643] but for the time we hear only of his brother-in-law, William de Say, as actively embracing his cause.[644] He must, however, have relied on at least the friendly neutrality of his relatives, the Clares and the De Veres, in Cambridgeshire, Suffolk, and Essex, as well as on the loyalty of his own vassals. It is possible, from scattered sources, to trace his plan of action, and to reconstruct the outline of what we may term the fenland campaign. Fordham, in Cambridgeshire, on the Suffolk border, appears to have been his base of operations. Here supplies could reach him from Suffolk and North Essex. He was thence enabled to advance to Ely, the bishop being at this time absent at Rome, and his forces being hard pressed by those which Stephen had despatched against them. The earl gladly accepted their appeal to himself for assistance, and was placed by them in possession of the isle, including its key, Aldreth Castle.[645] He soon made a further advance, and, pushing on in the same direction, burst upon Ramsey Abbey on a December[646] morning at daybreak, seized the monks in their beds, drove them forth clad as they were, and turned the abbey into a fortified post.[647] He was probably led to this step by the confusion then reigning among the brethren. A certain scheming monk, Daniel by name, had induced the abbot to resign in his favour. The resignation was indignantly repudiated by the monks and the tenants of the abbey, but Stephen, bribed by Daniel, had visited Ramsey in person, and installed him by force as abbot only eighteen days before the earl's attack.[648] It is, therefore, quite possible that, as stated in the Walden Chronicle, Daniel may have been privy to this gross outrage. In any case the earl's conduct excited universal indignation.[649] He stabled his horses in the cloisters; he plundered the church of its most sacred treasures; he distributed its manors among his lawless followers, and he then sent them forth to ravage far and wide. In short, in the words of the pious chronicler, he made of the church of God a very den of thieves.[650]
