21. Charge at the gates of Sedan! (22)

The Defense Army Headquarters and Charlemagne Army Headquarters had many differences when formulating their operations plans. Besides the known facts—that one side stuck to tradition with wild ideas, while the other was meticulous and far ahead—few knew that the Defense Army Headquarters would leave considerable space for front-line units to flexibly respond in their planning. It wasn't that every detail had to be as precise as a train timetable. This approach not only provided contingency space for unforeseen events, preventing uncontrollable chain reactions or missing valuable combat opportunities due to strict adherence to a schedule, but it also allowed for more autonomy among frontline commanders, enabling them to act without reservation.
