Hereward the Last of The English by Charles Kingsley

If Torfrida was exhausted, so was Hereward likewise. He knew well that a repulse was not a defeat. He knew well the indomitable persistence, the boundless resources, of the mastermind whom he defied; and he knew well that another attempt would be made, and then another, till -- though it took seven years in the doing -- Ely would be won at last. To hold out doggedly as long as he could was his plan: to obtain the best terms he could for his comrades. And he might obtain good terms at last. William might be glad to pay a fair price in order to escape such a thorn in his side as the camp of refuge, and might deal -- or, at least, promise to deal -- mercifully and generously with the last remnant of the English gentry. For himself yield he would not: when all was over, he would flee to the sea, with Torfrida and his own housecarles, and turn Viking; or go to Sweyn Ulfsson in Denmark, and die a free man.

The English did not foresee these things. Their hearts were lifted up with their victory, and they laughed at William and his French, and drank Torfrida's health much too often for their own good. Hereward did not care to undeceive them. But he could not help speaking his mind in the abbot's chamber to Thurstan, Egelwin, and his nephews, and to Sigtryg Ranaldsson, who was still in Ely, not only because he had promised to stay there, but because he could not get out if he would.
