And in Ely a great council was held, after which Sweyn and all his Danes returned home. For as Sweyn truly said, "While William the Frenchman is king by the sword, and Edgar the Englishman king by proclamation of earls and thanes, there seems no room here for Sweyn, nephew of Canute, king of kings." To which Hereward could advance no good reason to prove that there was. Anon came William of Ely, and built a floating bridge a full half-mile in length across the black abyss of mud and reeds that yawned between the island and the mainland. But the bridge was unable to bear the weight of all the French who crowded on to it; the fastenings at the shore-end broke, and the bridge itself overturned, so that all upon it were thrown into the mud and miserably drowned. Whereon William withdrew his forces to Brandon for a space, and Hereward, being minded to find out for himself what next was purposed against the island, followed him thither, with shorn hair and beard, and disguised as a travelling potter. Anon he came to William's palace with his good mare Swallow, bearing on her back a load of crockery. At the palace he narrowly escaped recognition, being sent to the kitchen, where he got into a quarrel with the scullions. In consequence of which he was haled before William himself, who quickly detected that he was other than he pretended. "Look you," said William, "you are no common churl--you have fought too well for that; show me your arm." Hereward drew up his sleeve. "Potters do not carry sword-scars like these, nor are they tattooed like English thanes. Hold up thy head, man, and let me see thy throat. "Aha! so I suspected. There is fair ladies' work there. Is not this he who was said to be so like Hereward? Very good. Put him in ward till I come back from hunting, but do him no harm. For were he Hereward himself, I should be right glad to see Hereward safe and sound; my man at last, and earl of all between Humber and the Fens." Whereupon Hereward was clapped into an outhouse, whence he escaped forthwith by the simple device of cutting off the head of the man sent to fetter him, and the good mare Swallow bore him back to Ely in safety. A little later William came again to Ely and built a stronger bridge, but this the English destroyed by fire, with many of the French on it, setting the reeds aflame on the windward side of it. Some other scheme must now be thought out, and the one that pleased William most was to send to the monks a proclamation that, unless they submitted within a week, all their lands and manors outside the island would be confiscated. Furthermore, that if Hereward would submit he should have his lands in Bourne, and a free pardon for himself and all his comrades. To which message Sir Ascelin and Ivo Taillebois, not being over desirous of having Hereward as a neighbour, saw fit to add a clause exempting Torfrida from the amnesty, but that she should be burnt on account of her abominable and notorious sorceries.
