Waterloo (18 June 1815) is often treated as a decisive battle of personalities, but it is also a case about command under uncertainty: delayed information, ambiguous orders, dispersed forces, and timing problems that no commander could fully control.

This case is used here to emphasize a simple point: command is a relationship, but coordination is an infrastructure. When communications are slow, terrain is complex, and the situation changes rapidly, the gap between intent and execution widens.

Questions for analysis

  • What did each commander believe the situation was at each major decision point?
  • Which delays were unavoidable (friction) and which were produced by the C2 system?
  • Where would mission command have helped, and where would it have increased divergence?
  • How did the absence (or presence) of staff systems shape the battle’s decision points?
