Fire at command, by platoon, by battalion, etc., is used in case the enemy having repulsed skirmishers and arrived at a reasonable range either charges or opens fire for effect himself. If the latter, fire is reciprocal and lasts until one or the other gives way or charges. If the enemy charges, what happens? He advances preceded by skirmishers who deliver a hail of bullets. You wish to open fire, but the voices of your officers are lost. The noise of artillery, of small arms, the confusion of battle, the shrieks of the wounded, distract the soldiers' attention. Before you have delivered your command the line is ablaze. Then try to stop your soldiers. While there is a cartridge left, they will fire. The enemy may find a fold of ground that protects him; he may adopt in place of his deployed order columns with wide intervals between, or otherwise change his dispositions. The changing incidents of battle are hidden by smoke and the troops in front, from the view of the officers behind. The soldiers will continue to fire and the officers can do nothing about it. All this has been said already, has been gone into, and fire at command has been abandoned. Why take it up again? It comes to us probably from the Prussians. Indeed the reports of their general staff on their last campaign, of 1866, say that it was very effectively employed, and cite many examples. But a Prussian officer who went through the campaign in the ranks and saw things close up, says, "In examining the battles of 1866 for characteristics, one is struck by a feature common to all, the extraordinary extension of front at the expense of depth. Either the front is spun out into a single long thin line, or it is broken into various parts that fight by themselves. Above all the tendency is evident to envelop the enemy by extending the wings. There is no longer any question of keeping the original order of battle. Different units are confused, by battle, or even before battle. Detachments and large units of any corps are composed of diverse and heterogeneous elements. The battle is fought almost exclusively by columns of companies, rarely of half-battalions. The tactics of these columns consists in throwing out strong detachments of skirmishers. Gradually the supports are engaged and deployed. The line is broken, scattered, like a horde of irregular cavalry. The second line which has held close order tries to get up to the first promptly, first to engage in the fight, also because they suffer losses from the high shots directed at the first line. It suffers losses that are heavy as it is compact and supports them with impatience as it does not yet feel the fever of battle. The most of the second line then forces entry into the first, and, as there is more room on the wings, it gravitates to the wings. Very often even the reserve is drawn in, entirely, or so largely that it cannot fulfill its mission. In fact, the fighting of
