It is for the first that the eye of the good skirmisher continually seeks. The second, after fire completely opens, turned even to best advantage, _is worth but little more than no cover at all_; and is worse than no cover at all, if the men, which they are much disposed to do, collect in groups behind it. In this way, that very frequent out-lying piquet defence, abattis across roads, is often more injurious to friends than to foes. Instead of being planted, as an obstacle to the enemy, 100 yards in front of the intended line of defence, it is but too commonly placed _on_ that line, and when the struggle comes, is thickly occupied as a sort of rampart. On such striking objects the enemy’s fire concentrates, every ball goes through, and the loss behind is severe. Skirmishers must not only seek for cover, but _make the best of it_. Good cover loses half its advantages if stupidly occupied, and ingenuity will often make bad cover ball-proof. However, notwithstanding all that may be said in favour of “making the best of cover,” it must be thoroughly remembered, that this duty, at the moment of a close attack, is altogether secondary to those of courage and activity. When it comes to short distances, the quicker the affair is settled the less will be the loss of the assailants; and the more daring the front exhibited, the greater the probabilities of success. At every change of situation supports should, if possible, be placed under cover by their commanders; if exposed, as large bodies they form most inviting marks to the enemy’s long shots. This precaution, when opportunities offer, should not be forgotten on the drill field.[9] V. One man at 200 yards[10] is a very small mark. Two abreast together, a tolerably good one; three abreast together should almost always be hit, and four never be missed. Our opponents, therefore, in skirmishing, cannot serve us better than by grouping together; and that which we would wish them to do, we ourselves must carefully avoid. Skirmishers should move in single files,[11] except in thick “concealing cover,” when two or three together may, without exposure, increase mutual confidence; or behind patches of “ball-proof cover,” on which small groups may concentrate as to temporary breast-works; in either case extending again at once when good cover ceases. Even in single files, men loading should incessantly cover with precision their file leaders, so as to offer marks of but one in front. _In skirmishing, more than in any other branch of warfare, men may be uselessly thrown away_; and therefore in this, more than in any other, economy of life and limb should form a paramount object of attention.
