Nestled between the bastions of the glacis there are a couple of works that, when looking at them from the satellite image, one can't imagine why an attacker would stupidly scramble into this passageway of dismemberment...but if the Kaiser's troops were scuttling along, being fired at from all sides, this might have looked like an attractive cover option. Naturally, there were plenty of gun ports therein, manned by defenders who just couldn't wait to defend the living hell out of anyone who stumbled into their sights.
