Mass will be formed from line of battalions in a similar manner.
In forming mass on a central battalion, the battalions on the right and left will pass into mass left arm to left arm.
A line of battalions changing position.
A line of battalions will change position on a flank battalion as follows:—The battalion of formation will be wheeled into the required alignment, the others forming on it, the seconds in command marking the spots where the inner flanks will rest.
106. Marching in line of battalions either in column or quarter column.
When a brigade marches in line of battalions, a battalion of direction will be named. The remaining battalions will march by their inner flanks, the seconds in command riding on the flank next to the regulating battalion, and notifying to the commanding officers whether interval is being correctly kept or not. Signals should be agreed on for this purpose; the commanding officer should watch for them, and direct the movement of the battalion accordingly.
When it is necessary to advance in echelon of battalions, intervals will be preserved on the principles described in 117.
