The incidents related in this chapter took place a few years back during a certain manoeuvre season, and for obvious reasons it is impossible to indicate the men, forces concerned, or locality more closely than that. The forces concerned were an army corps advancing from the south, and one advancing from the north, toward each other, with a view to trying conclusions under manoeuvre conditions. The story concerns scouts of the blue force, advancing from the north--it was one of these scouts of the blue force who told the story. It must not be taken as a typical story of army life, for the circumstances under which these men were placed were exceptional, agreeably so; it is, however, sufficiently typical for relation, in that it embodies things actually accomplished by soldiers of the Army of the Republic. Like most things that happen both in manoeuvres and in war, it could never happen again. The blue force, with at least fifty miles to go after leaving barracks, knew that the red force would have further to travel, since the limits of the manoeuvre area were clearly marked out on maps supplied to the officers taking part, and each force knew from what garrison the force opposing it was coming. Beyond this, though, neither officers nor men of the blue force knew from what direction the "reds" would attack, and the composition and strength of each arm of the "reds" was for the "blues" to find out; that is what cavalry patrols and scouting parties are for: to ascertain the strength and disposition of the enemy; and, in order to make the manoeuvres as much like real war as possible, each side was kept in ignorance, as far as might be, of the movements of the other. There were two days of steady marching, through days that were not too warm and nights that were decidedly cold. Marching in column, this business, with plenty of dust along the roads and the squadrons closed up so that one's horse's nose was not far from the tail of the horse in the next rank. In the cool weather the horses travelled well, and the cavalry got into camp fairly early in the afternoon, when the bivouacs were made and the men rested and ate, after seeing to the needs of their horses. Late in the afternoon of the second day a canvas town came into view after the troops had passed over a small river, and here the regiments went into camp. At twelve o'clock that night the manoeuvre period was to start, and no action of any kind bearing on the actual manoeuvres might be undertaken until midnight had passed, though commanders might make their plans and allot their units and men to the various parts they intended the latter to play in the struggle for points in the game. The troops themselves looked forward to an exciting time: in the blue army, every man knew that he was to capture a "red" if the chance came his way; he must act as in real war, except that the cartridges would be blank and the business would be one of sport with the grimness of war left out.
