Just beneath Bolt Head we observed the ruins of an old castle, once a stronghold of importance, which held out bravely for the Royalists under the governor, Sir Edward Fortescue.  For four months he and his gallant followers withstood the numberless cannon-shot poured in from the heights above, and at length only yielded on honourable terms to the leader of the Parliamentary forces, who allowed them to walk out with their arms and colours flying.
