The first thing which overpowers the imagination—and we may indeed say, also the understanding—is the diminution of the masses; then the loss of ground, which takes place always, more or less, and, therefore, on the side of the assailant also, if he is not fortunate; then the rupture of the original formation, the jumbling together of troops, the risks of retreat, which, with few exceptions may always be seen sometimes in a less sometimes in a greater degree; next the retreat, the most part of which commences at night, or, at least, goes on throughout the night. On this first march we must at once leave behind, a number of men completely worn out and scattered about, often just the bravest, who have been foremost in the fight who held out the longest: the feeling of being conquered, which only seized the superior officers on the battlefield, now spreads through all ranks, even down to the common soldiers, aggravated by the horrible idea of being obliged to leave in the enemy’s hands so many brave comrades, who but a moment since were of such value to us in the battle, and aggravated by a rising distrust of the chief, to whom, more or less, every subordinate attributes as a fault the fruitless efforts he has made; and this feeling of being conquered is no ideal picture over which one might become master; it is an evident truth that the enemy is superior to us; a truth of which the causes might have been so latent before that they were not to be discovered, but which, in the issue, comes out clear and palpable, or which was also, perhaps, before suspected, but which in the want of any certainty, we had to oppose by the hope of chance, reliance on good fortune, Providence or a bold attitude. Now, all this has proved insufficient, and the bitter truth meets us harsh and imperious.
All these feelings are widely different from a panic, which in an army fortified by military virtue never, and in any other, only exceptionally, follows the loss of a battle. They must arise even in the best of Armies, and although long habituation to War and victory together with great confidence in a Commander may modify them a little here and there, they are never entirely wanting in the first moment. They are not the pure consequences of lost trophies; these are usually lost at a later period, and the loss of them does not become generally known so quickly; they will therefore not fail to appear even when the scale turns in the slowest and most gradual manner, and they constitute that effect of a victory upon which we can always count in every case.
We have already said that the number of trophies intensifies this effect.
It is evident that an Army in this condition, looked at as an instrument, is weakened! How can we expect that when reduced to such a degree that, as we said before, it finds new enemies in all the ordinary difficulties of making War, it will be able to recover by fresh efforts what has been lost! Before the battle there was a real or assumed equilibrium between the two sides; this is lost, and, therefore, some external assistance is requisite to restore it; every new effort without such external support can only lead to fresh losses.
