Collecting others of his scattered followers, Hereward kept up his warfare from his own house at Bourn, continually harassing the Normans, until at length he took prisoner his old enemy, Ivo Taillebois, and, as the price of his liberty, required him to make his peace with the Conqueror. This was good news to William, who highly esteemed his valor and constancy, and could accuse him of no breach of faith, since he had made no engagements to him. Hereward was therefore received as a subject of King William, retained his own estate, and died there at a good old age, respected by both Saxons and Normans. There is, indeed, an old Norman-French poem, that declares it was for the love of a noble Saxon lady, named Alftrude, that Hereward ceased to struggle with the victors. According to this story, Alftrude, an heiress of great wealth, was so charmed by the report of Hereward’s fame, that she offered him her hand, and persuaded him to make peace with William. It is further said, that one afternoon, as he lay asleep under a tree, a band of armed men, among whom were several Bretons, surrounded and murdered him, though not till he had slain fifteen of them. But this story is not likely to be true, since we know that Hereward was already married, and the testimony of more than one ancient English chronicler declares that he spent his latter years in peace and honor. He was the only one of the Saxon chieftains who thus closed his days in his native home--the only one who had not sought to preserve his own possessions at the expense of his country, and who had broken no oaths nor engagements. His exploits are told in old ballads and half-romantic histories, and it is not safe to believe them implicitly, but his existence and his gallant resistance are certain. Many years after, the remains of a wooden fort, the citadel, so to speak of the Camp of Refuge, still existed in the Isle of Ely, and was called by the peasantry Hereward’s Castle. The treacherous monks of Ely were well punished by having forty men-at-arms quartered on their Abbey.
