While Edwin retired to his estate in the north, with a view of commencing an insurrection, Morcar took shelter in the Isle of Ely, with the brave Hereward, who, secured by the inaccessible situation of the place, still defended himself against the Normans.

But this attempt served only to accelerate the ruin of the few English who had hitherto been able to preserve their rank or fortune during the past convulsions.
William employed all his endeavors to subdue the Isle of Ely; and having surrounded it with flat-bottomed boats, and made a causeway through the morasses to the extent of two miles, he obliged the rebels to surrender at discretion.

Hereward alone forced his way, sword in hand, through the enemy; and still continued his hostilities by sea against the Normans, till at last William, charmed with his bravery, received him into favor, and restored him to his estate.

Earl Morcar, and Egelwin, bishop of Durham, who had joined the malecontents, were thrown into prison, and the latter soon after died in confinement.

Edwin, attempting to make his escape into Scotland, was betrayed by some of his followers, and was killed by a party of Normans, to the great affliction of the English, and even to that of William, who paid a tribute of generous tears to the memory of this gallant and beautiful youth.
