In a great battle, involving large bodies of troops, each corps or division commander must do in a smaller way what the general-in-chief does on a larger scale. Each has charge of the battle on a certain part of the line. Each must take care of things within his own jurisdiction, and be ready at a moment’s notice to respond to the demand of the commanding general for troops with which to help out elsewhere.
These are the generalities. Let us now come to the battle itself.
When the skirmishers of the advancing army meet the skirmishers of the resisting army, there is apt to be some pretty hot fighting for a time, and sometimes the artillery is considerably involved in it. But this is not the real thing; it is a mere preliminary to the actual battle.
The army that is standing on the defensive holds its lines in position—every battery placed where it will do the most good, and every infantryman lying down and taking the utmost advantage of every tree stump, log, or inequality of the ground, to protect himself as much as possible.
The men on horseback are either in front with the skirmishers, minutely observing the strength and movements of the enemy, or, having finished that work, are thrown out at the two ends of the lines, called “flanks,” to watch there for possible movements of the enemy that might be otherwise unobserved. They are within call of any part of the line where need of them may arise.
While the skirmishers are doing their work, the heaviest strain of war falls on the nerves of the men in line of battle.
They have nothing to do but wait.
They wait with the certain knowledge that in a few minutes the advancing army will throw men forward, and thus convert its skirmish line into a line of attack; while on their own side they know that their skirmish line, after making all of discovery that temporary resistance can accomplish, will fall back, and that then the crucial conflict will begin.
Then comes the uproar of battle,—the dust, the blood, the advance, the retreat, the shock of arms, the murderous volleys of the infantry, the thunder storm of artillery; in short, the final desperate conflict of determined men for the mastery, all of them directed by cool-headed commanders, sitting on their horses at points of vantage for observation, and directing a reinforcement here, a withdrawal of men there, the hurrying of artillery to one point, an onset of cavalry at another, and at a critical moment an up-and-at-them charge with the bayonets. That usually ends matters one way or the other at the point involved. For only two or three times in any war do men with fixed bayonets on one side actually meet in physical shock men armed with fixed bayonets on the other.
Wherever there is advantage on either side, the general commanding that side throws troops forward in as heavy masses as possible to make the most of it. If one line or the other be broken, every conceivable effort is made to convert the breach into victory. And if victory comes, the cavalry thunder forward in pursuit and in an endeavor to convert the enemy’s defeat into rout.
