when william of normandy came over the sea, and took the crown of england, many english people would not call him king. the young lord hereward was one of these. he and his men made for themselves a "camp of refuge" among the reeds and rushes on the marshes. all day they lay there, hidden from view by the mists which rose from the watery ground, and at night they came out, and attacked the normans in their tents, and burned their towns.
