To advance in the open against an enemy, even when that enemy is not under cover but simply lying on the ground, involves one of two alternatives. Either the advancing force is annihilated by the time it gets to within 500 yards of the enemy, or it is forced to lie down 1,500 yards away or less and return the enemy's fire. But the latter alternative produces a state of things which has never been known in the history of war. Both the advancing and the expectant forces are put out of action. Neither can advance and, what is more serious still, neither can _retire_. This contingency opened up an entirely new field of tactics. The general who can, with a smaller force, succeed in putting out of action, at least for the time being, a greater force of his opponent, is more likely to win his battle. In the future, the curious sight will be seen of regiments or even brigades lying flat on the ground, doing little damage to the enemy and suffering little loss, and yet being as useless to their general as if they were snoring in their barracks at home. Perhaps this is too sweeping, for their presence in front of the enemy will have the advantage of containing him, but in the open, across which an enemy has to advance, a containing force of a proportion of one man to five of the enemy is quite sufficient. Therefore the use of a brigade to contain a brigade would be a waste of material. Even those of us who have followed closely and carefully all the stages of the campaign do not yet perceive the magnitude of the changes involved by the use of modern rifles, but they appear to me to be so radical that instead of describing them as fresh developments, I would prefer to give an affirmative answer to the title of this article. But there yet remains to be discussed the question of the _arme blanche_--the bayonet, the weapon with which our gallant army has won so many of its victories. I have heard not a few officers declare that this war will be known in history as the last war in which a British soldier carried a bayonet. But is the discarding of the bayonet to be one of the results of the use of the new rifle and the smokeless powder? When fighting against an enemy who does not carry it, the force which is armed with a bayonet has a tremendous moral superiority. In the present war, there have been one or two cases--one, particularly, at Slingersfontein--where the Boer has made a frontal attack on a prepared position held by us. The attacks have always been made along the tops of kopjes which afforded excellent cover for a stealthy advance. The obvious way to meet such attacks was to wait until the enemy came close enough to allow the use of the bayonet, and this was done with great success at Slingersfontein. So that it may be laid down that in cases where one only of two opposing forces is armed with the bayonet, it is obviously to its advantage that the enemy should in attacking come to close quarters.
