It is strange how little the law of battles is understood by most persons. Most persons imagine that in a fight between our Navy and another navy, or between our Army and the army of an enemy, although the enemy might have the advantage in the number of ships and in the size and range of guns, the advantage would be immaterial and one which might be balanced by the superiority of our personnel, and that, although we might be somewhat short of the required field batteries and ammunition, the superior fighting qualities of our men would render them more than a match for the enemy, even in the face of superior gun-fire. It does not appear to have been fully recognized even by the advocates of better equipment for the American Army, how vitally important is length of range in field artillery. In the Boer War, the British field batteries found themselves at great disadvantage in face of the longer French guns of the Boer batteries. In the present European war, the great long-range German howitzers, pummeling forts into heaps of scrap, and their plunging fire blowing great craters along the battle-front, spread terror in the ranks of the Allies, similar to the terror that the Romans felt when the fierce Gothic giants slid down the Alps into the vineyards of Italy. But the long-range French field-artillery soon restored confidence, for it was found that the French field batteries could outrange the German batteries. We need field-guns of longer range. We need field-guns that shall not only equal in range those now in use in Europe, but also we need guns of even longer range. We should have field-guns of a range sufficient to command sky-line from opposing sky-line. Here is an opportunity for the vaunted American genius to assert itself. It is necessary that the facts as they actually are should be recognized and appreciated. Victory in a naval battle today depends absolutely upon the weight of the broadsides and the speed of the vessels, which enables them to manoeuvre and choose positions of advantage with respect to the enemy; while victory or defeat in a land fight depends upon the weight of gun-fire, which can be directed against the positions of an enemy. The actual number of infantry engaged is of secondary importance. It is artillery that is of supreme importance. Should we be involved, our field artillery must pave the way with the dead bodies of the enemy before our infantry can advance. Also, the batteries of the enemy must be silenced by our own batteries before they, with their gun-fire, shall be able to silence ours. Other things being equal, therefore, it is the number of field batteries that, more than anything else, turns the tide of battle for defeat or victory. If the enemy's guns have a longer range than ours, then they will be able to silence our batteries while far beyond the range of our guns. They will be able to destroy our artillery, while we should not be able even to injure theirs.
