When the progress of an order is interrupted, commanding officers will conform, as quickly as possible, to the movement they see in execution. 4. Intervals and distances of thirty paces between battalions and brigades, and sixty between divisions, will be preserved in all formations, unless otherwise ordered. 5. A battalion will always be named to direct, the remaining battalions preserving their intervals from that battalion. 6. In brigade and division drill, battalions will be in quarter column unless otherwise ordered. 7. In all interior movements of a brigade, battalions will move to their places by the shortest lines, moving, when possible, by the diagonal march. 8. _Division drill._--The principles laid down for brigade drill are equally applicable to division drill. =104.= _A brigade wheeling from mass into line of battalions and vice versâ._ A brigade can be wheeled into line of battalions from mass and _vice versâ_, by the battalions wheeling as in Battalion Drill, =95=. The above movements may be performed either at the halt or on the move. =105.= _A mass deploying into line of battalions and vice versâ._ The battalion which is the point of formation stands fast. The remaining battalions will be moved by their commanding officers by the shortest line to the spot where their inner flank will rest, this spot being marked by the second in command. If the deployment is in an oblique direction, the battalion of formation will be formed on the required alignment by its commanding officer, in accordance with the instructions of the brigadier. The deployment will then be carried out as already described. 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=. FORMATIONS APPLICABLE TO SAVAGE WARFARE.
