CONVOYS
Callwell defines a convoy as "a column of non-combatants guarded by a comparatively speaking small escort." The object of this escort is to hold off all hostile parties and to get the convoy to its destination in safety. Escorts will generally have to be reduced to the smallest possible size in order not to deprive the fighting force of men. They will therefore always act on the defensive, while endeavouring to keep moving with the convoy, which will only be halted when compelled to do so for its own safety. When the escort consists of the three arms, machine guns may be used to reduce the number of infantry required very considerably, while adding to the defensive power of those necessary.
In minor operations where every available rifle is required with the fighting force, machine guns will be found invaluable to replace infantry. Their exact position with the convoy must depend upon its composition and length and the number of guns available. The principle of having a machine gun, or where possible a section, at the head and another at the rear end of the line of wagons or pack animals is sound, as these are the vital points, and an attack on the centre can be met by a cross fire from these positions. If the convoy is unduly long, another gun or section may be placed in the centre. Should it be necessary to form laager, the machine guns in the front and rear enable this
