The rally dismounted, is always executed at a run. (Fig. 49.) [Illustration: FIG. 49, par. 416.] THE MOUNTED ATTACK. =417.= The mounted attack is made with the pistol or saber in accordance with the principles indicated in pars. 562-565. The typical saber charge is executed in =line=. Under some circumstances, as in the attack of a dispersed enemy, etc., a saber charge may be made by troopers deployed as =foragers=. The pistol attack is usually made in foragers. In exceptional circumstances (as in breaking out from an ambush, attacking in a narrow road, etc.) it may be made =in line= or =in column of fours, twos, or troopers=. =418.= Cohesion in the line and vigor in the shock are essential to the success of the _saber charge_. High speed is necessary for the desired shock; and in the saber charge, as executed in combat, the horses are, at the culmination of the charge, habitually "turned loose" and urged to the highest speed. This, except with men and horses that are highly trained, necessarily involves _loss of control_ over the horse on the part of the trooper. The saber charge, executed with poorly trained horsemen, especially if on imperfectly trained or excitable house's, is apt to be futile as regards the instruction of the trooper and to result in more or less permanent loss of control over the horses. _Control of the mount_ by the trooper is essential during the execution of the _pistol attack_ (ordinarily made in line of foragers), and is, of course, necessary during march and maneuver. For these reasons it is considered advisable that the first instruction of the recruit in the actual saber charge be deferred until after platoon instruction and that it be given then only after the troop commander is satisfied that the recruit's progress in horsemanship and in the use of his weapon has advanced to a point when the exercise will be of value.
