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.
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.
