The experience of the evening ought always to serve the day following; but as the next day is never identical with the evening before, the counsel of experience can not be applied to the latter. When confused battalions shot at each other some two hundred paces for some time with arms inferior to those of our days, flight commenced at the wings. Therefore, said experience, let us reenforce the wings, and the battalion was placed between two picked companies. But it was found that the combat methods had been transformed. The elite companies were then reassembled into picked corps and the battalion, weaker than ever, no longer had reenforced wings. Perhaps combat in open order predominates, and the companies of light infantrymen being, above all, skirmishers, the battalion again is no longer supported. In our day the use of deployed battalions as skirmishers is no longer possible; and one of the essential reasons for picked companies is the strengthening of the battalion. The question has been asked; Who saved the French army on the Beresina and at Hanau? The Guard, it is true. But, outside of the picked corps, what was the French army then? Droves, not troops. Abnormal times, abnormal deeds. The Beresina, Hanau, prove nothing to-day. With the rapid-firing arms of infantry to-day, the advantage belongs to the defense which is completed by offensive movements carried out at opportune times. Fire to-day is four or five times more rapid even if quite as haphazard as in the days of muzzle loaders. Everybody says that this renders impossible the charges of cavalry against infantry which has not been completely thrown into disorder, demoralized. What then must happen to charges of infantry, which marches while the cavalry charges? Attacks in deep masses are no longer seen. They are not wise, and never were wise. To advance to the attack with a line of battalions in column, with large intervals and covered by a thick line of skirmishers, when the artillery has prepared the terrain, is very well. People with common sense have never done otherwise. But the thick line of skirmishers is essential. I believe that is the crux of the matter. But enough of this. It is simple prudence for the artillery to prepare the infantry action by a moment's conversation with the artillery of the enemy infantry. If that infantry is not commanded by an imbecile, as it sometimes is, it will avoid that particular conversation the arguments of which would break it up, although they may not be directed precisely in its direction. All other things being equal, both infantries suffer the same losses in the artillery duel. The proportion does not vary, however complete the artillery preparation.
