The finishing touches to the comedy of the shock-duel are given in the revised Mounted Infantry Manual of 1909; for, although in this connection the Cavalry Manual never breathes a word about its sister Arm, it is, as I have before mentioned, one of the regular duties of the Mounted Infantry to co-operate with the Cavalry, not only in reconnaissance, but in battle. Under the heading "Co-operation with Cavalry when Acting Offensively against Hostile Cavalry," the Mounted Infantry are to "seize points of tactical importance from which effective rifle and machine-gun fire can be brought to bear on the flanks of the opposing Cavalry before the moment of contact." We picture an amphitheatre, like Olympia, both rims of the horseshoe lined with hidden riflemen, and two solid blocks of Cavalry galloping towards one another in the arena below, and we are alarmed for the fate of the horsemen, exposed in such a formation to a sleet of bullets. But we come to a fortunate reservation. "Fire will rarely be opened upon the hostile Cavalry or Artillery until contact is imminent. The object aimed at is the defeat of the hostile Cavalry, and a premature opening of fire is liable to cause it to draw off and manoeuvre, in order to bring off the Cavalry encounter outside effective rifle-range." Surely some humorist of the Mounted Infantry, coerced by the General Staff into finding a rôle for his Arm which should not trench upon the sacred preserves of the Cavalry, penned these exquisite lines by way of stealthy revenge! What delicate consideration for the "knightly" weapons! What an eye for theatrical effect! What precautions against the disturbance of the collision by the premature discharge of vulgar firearms! And what a tactful show of apprehension lest these reminders of the degenerate twentieth century should scare away the old-world pageant to regions beyond "effective rifle-range"! It will be noticed that even the Artillery of the enemy is to be immune until "contact is imminent"--a somewhat doubtful risk to take without a written guarantee from the enemy that his Artillery will reciprocate the courtesy.
