Number Three is provided for by copious and complicated map
references.

Number Four is left to Providence--and is usually the best-conducted
feature of the excursion.

Under cover of night the Battalion sets out, in comparatively

Progress is not easy. It is a pitch-black night. By day, this road
(and all the countryside) is a wilderness: nothing more innocent ever
