One of our principal failings, as I have repeatedly mentioned, was lack of information. Owing to this, and the consequent loss of touch, commanders could not conduct operations intelligently or keep corps and army commanders and the Commander-in-Chief informed of what was happening. Every Japanese regiment laid down telephones as it advanced; we used to find their dead operators in our _trous de loup_, which showed that they were right up with the firing-line. With us touch was not infrequently lost even between whole corps and armies! The necessity for remedying this grave defect is obvious, and we must practise how to do this in peace. Not a regiment should be allowed to advance at manœuvres without at once being connected up by telephone with its brigade commander and the divisional staff, and it is essential that, as the information comes in by telegraph and telephone, the divisional corps and army staffs should at once fix on the maps the positions of both forces. Formerly commanders could watch the whole battlefield through a telescope from an eminence, could see their own troops, and could trace the position of the hostile infantry and artillery from the smoke. Now there is nothing to be seen. Often the troops are out of sight, and all that meets the eye are the puffs of smoke from the bursting shrapnel. Therefore orders and dispositions have to be worked out on the map, and we must learn how to keep these maps constantly up to time. In order that all intelligence may be at once noted, a “service of communication,” by means of motors, cyclists, and particularly of telegraph and telephone, might be organized, in addition to the ordinary reports brought in by mounted men. To attain these important results, considerable expense must be incurred in the creation of this “service of communication” or “service of information” of such a nature as to meet in every way the requirements of battle, of movement, and of rest. An adequate number of sapper units with regiments will not only help us in the capture of fortified positions strengthened by obstacles, but will assist us rapidly to adapt them for defence when taken. The work of the mining company in future wars will be great both in attack and defence, especially in defence. It should have charge of all explosives required for demolitions, including mines, pyroxyline bombs, and hand-grenades. The great effect of the bombs thrown by revolutionaries and anarchists points to their extensive use in war in the future. If fanatics can be found who will rush to certain death in order to kill peaceful citizens, it should certainly be possible to find devoted soldiers who will advance ahead of the firing-line and throw bombs into the enemy’s obstacles. Besides supply of field railway material for the army, each corps should have enough for thirty miles of line (steam or horse draught, according to circumstances). ARTILLERY.
