The dynamic nature of the British operation at Cambrai in 1917, in particular related to the actions of the British CINC Douglas Haig, provides useful insights into the nature of operational leadership for today. This is true in large part because the Cambrai operation came at a time when technology, tactics and strong political pressure came together to exert their combined influence on all levels of war, particularly the operational level. A similar situation exists today. The primary lessons which can be drawn from Haig's experience as an operational commander at Cambrai include; the need to define and communicate the commander's intent, an operational commander's need to avoid involving himself at the tactical level, and the requirement for an operational commander to examine carefully his motives for deciding on a particular course of action.
