Chapter XLIII: Part 2: of this directive, dealing with “Probable warlike

eventualities—Concentrations,” states:

“1. War on two fronts with focal point in the West.

“Suppositions. In the West France is the opponent. Belgium may
side with France, either at once or later or not at all. It is
also possible that France may violate Belgium’s neutrality if
the latter is neutral. She will certainly violate that of
Luxembourg.” (_C-175_)
