The scenario of the wargame that will be used will reinforce four key factors for the campaign s success, and if the original Schlieffen Plan had been maintained, they would certainly have been thought and executed: more siege artillery for the early phase of the maneuver of attack on the Belgian forts; better preparation and use of communications; logistics with more support troops, particularly to the far right wing, and with the possibility of tapping into enemy sources of conquest; and fewer troops withdrawn to serve the Russian front.
