The walls of the edifice itself were, moreover, strengthened by an embankment of earth to the height of perhaps four or five feet from the ground, above which narrow openings were made, in order to give to its garrison an opportunity of levelling their muskets; while on the top of the tower a small howitzer was mounted, from which either shot or shell could be thrown with effect into any of the lanes or passes near.
