The important object of the running and lying down in relieving under fire of course being, that the new and old lines of skirmishers should not be exposed when near together as large marks for the enemy’s shot.
One subdivision extended, the other in support.
Word of Command, “Form Square;”
or,
Bugle ....... “Alarm,” “Assembly.”
The right section of the support wheels back half a quarter circle (45°) on its left, the left section half a quarter circle on its right, stepping back one or two paces so as to let the left of the right section overlap its right. The right section wheels up by threes to the left, the left section by threes to the right, threes close to the front and then face outwards, thus forming half a three deep square with the angle to the front. “Fix bayonets” and “commence firing” (outward rank kneeling in reserve) if the front is clear and the enemy near. Skirmishers run in and form the two rear faces of the square three deep, keeping to the right and left in running in so as not to hinder the fire, and not fixing bayonets until in their places.
The faces of the square are wheeled back so as to stand diamond like in reference to the general line, in order that the fire may be thrown clear of your own neighbouring squares.
“Cease Firing.”
“Right subdivision cover the Front.”
The subdivision so ordered receives the words (as before) “unfix bayonets,” “trail arms,” “quick march,” “from the centre extend,” and proceeds to its extended line, the men of the other subdivision fall into their proper places in line two deep as the support.
