The guide continues to be the base and advances (par. 405) at the gait of march unless the leader indicates otherwise (pars. 337-_f_, 405). The troopers to the right of the guide move at a gallop obliquely to the right front; those to the left obliquely to the left front. The troopers take position abreast of the base in the same order as in line and at intervals of 3 yards measured from the side of the base. Should the right trooper be the guide, all oblique to the left; should the left trooper be the guide, all oblique to the right. In the execution of the corresponding dismounted movement (commands: 1. =Skirmishers=, 2. =MARCH=--par. 406) the troopers move to their places at a run, taking intervals of one-half pace, unless some other interval be indicated (pars. 368-_e_, 407.) (Fig. 37.) =409.= =Being in column of fours, twos, or troopers, to form foragers=: 1. =Right (left) front into foragers=, 2. =MARCH.= The _left trooper_ of the leading element of the column as the base of the deployment advances at the gait of march (par. 337-_a_) unless the leader indicates otherwise (pars. 337-_f_, 405), the other troopers of the leading element deploying as indicated in par. 408. The remaining troopers move obliquely to the right front at a gallop and extend the line in similar, manner, the order of the successive elements being the same, from left to right in line, as it formerly was from head to rear in the column. The possibility of the inversion of troopers in the fours as a result of forming foragers from column of _twos_ or _troopers_ should be kept in mind. No such inversion can occur in movements executed from column of fours. The movement described in this paragraph is one of those referred to in par. 468-_b_. (Fig. 41.) [Illustration: FIG. 47, par. 409.] =410.= =Being in disorder, to form foragers=: Foragers may be formed from any condition of dispersion or disorder by methods similar to those indicated in pars. 408 and 409. At the command: 1. =Foragers=, 2. =MARCH=, the troopers nearest the leader ride toward him at a gallop. The leader indicates the guide (par. 373), who follows the leader; the other troopers, moving at a gallop, take position, with the proper interval, on the right and left of the guide, without regard to order. Line of foragers from a condition of disorder may also be formed by first rallying the squad (par. 416) and then forming foragers. Dismounted, skirmishers may similarly be formed. =411.= =Being deployed as foragers, to march to a flank=: 1. =By the right (left) flank=, 2. =MARCH.= Each trooper turns 90° to the right and marches in the new direction (par. 389). A column of troopers at 4 feet distance results. The line of foragers may be resumed by again marching to the flank by the use of corresponding commands and methods. Gaits are regulated as in par. 337-_d_.
