Fig. 14.
The order by echelon upon the two wings [Fig. 14] is of the same nature as the perpendicular order, ([Fig. 11],) being, however, better than that, because, the echelons being nearest each other in the direction where the reserve would be placed, the enemy would be less able, both as regards room and time, to throw himself into the interval of the center and make at that point a threatening counter-attack.
