Furthermore, if we are not at the start of a campaign, this fresh Corps may itself be a composite formation of odds and ends withdrawn from other Corps, which throws a light on the strength of the forces the belligerent still has at his disposal and the proximity of the moment when his forces shall be definitely inferior to the enemy’s, which gives to the operation on which this Corps is about to engage a different meaning, because, if it is no longer in a condition to make good its losses, its successes even will only help mathematically to bring it nearer to its ultimate destruction. And then, the serial number of the Corps that it has facing it is of no less significance. If, for instance, it is a much weaker unit, which has already accounted for several important units of the attacking force, the whole nature of the operation is changed, since, even if it should end in the loss of the position which the defending force has been holding, simply to have held it for any length of time may be a great success if a very small defending force has been sufficient to disable highly important forces on the other side.
