We have two further lines of story to follow, one of history, the other of romance; one that of the reward of the monks for their treachery, the other that of the later story of Hereward the Wake. Abbot Thurston hastened to make his submission to the king. He and the inmates of the monastery sought the court, then at Warwick, and humbly begged the royal favor and protection. The story goes that William repaid their visit by a journey to Ely, where he entered the minster while the monks, all unconscious of the royal visit, were at their meal in the refectory. The king stood humbly at a distance from the shrine, as not worthy to approach it, but sent a mark of gold to be offered as his tribute upon the altar. Meanwhile, one Gilbert of Clare entered the refectory, and asked the feasting monks whether they could not dine at some other time, and if it were not wise to repress their hunger while King William was in the church. Like a flock of startled pigeons the monks rose, their appetites quite gone, and flocked tumultuously towards the church. They were too late. William was gone. But in his short visit he had left them a most unwelcome legacy by marking out the site of a castle within the precincts of the monastery, and giving orders for its immediate building by forced labor. Abbot Thurston finally purchased peace from the king at a high rate, paying him three hundred marks of silver for his one mark of gold. Nor was this the end. The silver marks proved to be light in weight. To appease the king's anger at this, another three hundred silver marks were offered, and King William graciously suffered them to say their prayers thenceforward in peace. Their treachery to Hereward had not proved profitable to the traitors. If now we return to the story of Hereward the Wake, we must once more leave the realm of history for that of legend, for what further is told of him, though doubtless based on fact, is strictly legendary in structure. Landing on the coast of Lincolnshire, the fugitives abandoned their light ships for the widespreading forests of that region, and long lived the life of outlaws in the dense woodland adjoining Hereward's ancestral home of Bourne. Like an earlier Robin Hood, the valiant Wake made the greenwood his home and the Normans his prey, covering nine shires in his bold excursions, which extended as far as the distant town of Warwick. The Abbey of Peterborough, with its Norman abbot, was an object of his special detestation, and more than once Turold and his monks were put to flight, while the abbey yielded up a share of its treasures to the bold assailants.
