When the various portions of the army are to be represented by flags, each flag should be made to represent a company, a battery, or a squadron, but the flags should be so disposed as to oblige patrols to estimate the strength of the columns by their length, as in war there would not often be time or opportunity to count the separate tactical groups of the enemy. Too few flags should not, however, be used, but rather as many as possible, so as to produce the effect of a continuous column on the move, infantry and artillery being clearly indicated. The detachments of cavalry that would in actual warfare be stationed at different points along the column might with advantage be represented by real cavalry, who would be able to pursue the enemy's horsemen. Artillery patrols might also relieve the cavalry of this duty, and, in difficult country, march on the flanks of the column, thereby making matters more difficult for the hostile scouts. All measures of this description would greatly assist in giving to manoeuvres the character of real warfare, and in increasing the difficulties in the way of the far-too-easy peace-time reconnaissance. Umpires need not confine themselves to deciding the results of engagements. They might very well draw the attention of patrols that act in a manner incompatible with service conditions to the hostile spirit of the population, or, if necessary, bring about real or assumed attacks that would inflict such losses or damage on the patrols as they would probably have suffered in war. They can, in short, do much to give the manoeuvres a semblance of reality. The rôle of umpire is also a useful training for regimental officers. Regimental and squadron commanders cannot form a correct idea of the possibilities and functions of their reconnoitring detachments unless they have accompanied patrols as umpires. It is, in my opinion, impossible to go too far in the direction of making conditions resemble as much as possible those of actual warfare, as one of the greatest difficulties to be faced consists in sustaining the interest of the troops and the semblance of reality. Goethe, in his "Wilhelm Meister," remarks how rare it is to find among men "any kind of creative imagination." Nothing, indeed, is more difficult than to take a keen interest in hypothetical conditions. This truth applies particularly to soldiers, and the difficulty is one from which most peace exercises suffer.
