A major consequence of this innovation was the commander's loss of overall control of his forces due to his available means of communication which, at that time were visual (line-of-sight) or couriers, either mounted or on foot. The traditional concept of the elimination of uncertainty by means of "total obedience" was now obsolete and operational initiative, direction and control had to be assigned to a point further down the chain of command. In this new concept, commanders of distant detachments were required to exercise initiative in their decision making and von Moltke emphasised the benefits of developing officers who could do this within the limits of the senior commander’s intention.
