If we take rifle shooting alone into account, the length of range, the speed of fire, the better training of troops in the use of the rifle, and the invention of contrivances to aid markmanship, cause such effectiveness of fire that it would be quite possible for rival armies totally to annihilate each other. But a similar improvement has taken place in artillery. The introduction of the quick-firing gun has multiplied the speed of artillery fire many times over. The range has been increased by the perfecting of the structure of the guns, the use of nickel steel in the manufacture of projectiles, and the employment of smokeless powder of immense explosive force. Artillery fire will now not only be employed against attacking troops, but even more against supporting bodies, which must necessarily advance in closer order, and among whom, therefore, the action of artillery will be even more deadly. We may well ask the question whether the nerves of short-service soldiers will stand the terrible destructiveness of artillery fire. As a necessary consequence of the increase in the power of fire, we find the more frequent and more extended adoption of defences, and of cover for protection in attack and hampering the enemy. In addition, every body of men appointed for defence, and even for attack--if it is not to attack at once--must immediately entrench itself. The defenders, thus sheltered, and only requiring to expose their heads and hands, have an enormous advantage over the attacking party, which is exposed to an uninterrupted fire to which it can hardly reply. In the opinion of competent military writers, the war of the future will consist primarily of a series of battles for the possession of fortified positions, which will further be protected by wire obstructions, pitfalls, etc., to overcome which great sacrifices must be made. As infantry, even if weak in numbers, cannot be driven from an entrenched position without artillery fire, armies in future must find themselves mainly dependent upon artillery. If the defending artillery be equal in strength to that of the attackers, then the attacking artillery will be wiped out. If it be not equal in strength, then both may be wiped out. The losses will be so great that the artillery of both armies will be paralysed, or it might be that the artillery would inflict such heavy losses on the troops that the war would become impossible. Owing to smokeless powder, batteries of artillery are more exposed to the fire both of the enemy's artillery and of sharpshooters. A hundred sharpshooters at a distance of half a mile can, it is estimated, put a battery out of action in less than two minutes and a half. Let it be added that the high explosives used by modern artillery are extremely liable to explode, owing to being struck by the enemy, or owing to concussion caused by an enemy's shell, or to mishandling.
