They, moreover, serve to annoy the troops we are about to attack, by the incessant sharp buzzing of their deadly bullets among them, like so many bees, killing some and disabling others; and this, sometimes, to such a degree as to demoralize them.
It is said that, at Waterloo, the swarms of skirmishers that covered the French attacking columns so galled and excited the stationary columns and squares of some of the Allies, as to nearly drive them from the field.
(3.) On the flanks of a column, they cover them from attack.
(4.) They draw the enemy's fire prematurely, and thus render it comparatively ineffective.
(5.) They prevent the columns from halting to deploy and fire.
(6.) They may sometimes conceal the direction of the march of the attacking column, and even seize the guns that have been playing on it.
10. In defence, if they can encircle the enemy's advancing column, they may destroy it by their concentric fire.
11. In a retreat, skirmishers cover the rear, so long as the enemy attacks without cavalry.
12. The NEW RIFLED ARMS have obviously much increased the effectiveness of skirmishers.
B. HOW POSTED.
1. They should be always near enough to the main body to be supported by it, if hard pressed, and also to enable the main body to profit at once of any advantage that may have been gained by them.
2. They should cover the main body, both in front and in flank, except where the ground may render this impracticable or unnecessary; and, in defensive positions, they should occupy every point from which the enemy's skirmishers might annoy us.
3. In a defensive combat, they should be so posted as to take the enemy's attack in flank:
(1.) Because their fire will be thus the more destructive; and--
(2.) They will not be exposed to be driven back by the enemy's fire, or by his advance.
4. If thrown into an enclosure, they must have an easy exit. Skirmishers feeling themselves in danger of being cut off, will lose somewhat of that coolness which is so essential to their efficiency.
5. They should not be kept stationary behind a straight line, as a wall, a fence, or a hedge; for this would expose them to enfilade.
6. Skirmishers are only auxiliary to the main force, and are not capable, by themselves, of effecting any decisive result. Therefore, in order not to exhaust the men, heavy skirmishing lines should not be used, except to lead a decided advance, or to repel one.
7. The principle is, to post skirmishers so as to give them the maximum of shelter, whilst inflicting the maximum of loss on the enemy. This applies to the placing of the whole line, and to the separate groups. The way skirmishers produce their effect is by sharpshooting, which requires calmness; and the more completely sheltered they are, the calmer they will be, and the more deadly will be their aim.
C. HOW HANDLED.
1. Deploy them before coming within range of musketry; for infantry in compact order is a good target for the enemy.
2. They should be kept well in hand; especially at the moment of success, when they are in danger of rushing headlong to destruction.
3. Coming upon the enemy's main body, they should occupy him in front and flank till our own main body gets up.
4. Except in urgent cases, never deploy a line of skirmishers on a run; for this makes them lose breath and calmness, and, with their calmness, their accuracy of aim.
So, after deployment, avoid all rapid and violent movements.
5. Skirmishers become exhausted after long firing. The longer they continue out, the worse they shoot. Therefore, relieve them often.
6. Skirmishers should be accustomed to lie down at a given signal; as it is sometimes very important that both our artillery and infantry should be able to fire over them.
7. In retreat, skirmishers occupy every favorable point for holding the enemy in check.
