The laws of military discipline are very strict and imperious, and in theory they are never to be disobeyed. Officers and soldiers, of all ranks and gradations, must obey the orders which they receive from the authority above them, without looking at the consequences, or deviating from the line marked out on any pretext whatever. It is, in fact, the very essence of military subordination and efficiency, that a command, once given, suspends all exercise of judgment or discretion on the part of the one to whom it is addressed; and a good general or a good government would prefer generally that harm should be done by a strict obedience to commands, rather than a benefit secured by an unauthorized deviation from them. It is a good principle, not only in war, but in all those cases in social life where men have to act in concert, and yet wish to secure efficiency in action.
Danger of violating discipline.
An illustration.
And yet there are cases of exception—cases where the necessity is so urgent, or the advantages to be derived are so great; where the interests involved are so momentous, and the success so sure, that a commander concludes to disobey and take the responsibility. The responsibility is, however, very great, and the danger in assuming it extreme. He who incurs it makes himself liable to the severest penalties, from which nothing but clear proof of the most imperious necessity, and, in addition to it, the most triumphant success, can save him. There is somewhere in English history a story of a naval commander, in the service of an English queen, who disobeyed the orders of his superiors at one time, in a case of great emergency at sea, and gained by so doing a very important victory. Immediately afterward he placed himself under arrest, and went into port as a prisoner accused of crime instead of a commander triumphing in his victory. He surrendered himself to the queen's officers of justice, and sent word to the queen herself that he knew very well that death was the penalty for his offense, but that he was willing to sacrifice his life in any way in the service of her majesty. He was pardoned!
Plan of Nero.
Nero, after much anxious deliberation, concluded that the emergency in which he found himself placed was one requiring him to take the responsibility of disobedience. He did not, however, dare to go northward with all his forces, for that would be to leave southern Italy wholly at the mercy of Hannibal. He selected, therefore, from his whole force, which consisted of forty thousand men, seven or eight thousand of the most efficient and trustworthy; the men on whom he could most securely rely, both in respect to their ability to bear the fatigues of a rapid march, and the courage and energy with which they would meet Hasdrubal's forces in battle at the end of it. He was, at the time when Hasdrubal's letters were intercepted, occupying a spacious and well-situated camp. This he enlarged and strengthened, so that Hannibal might not suspect that he intended any diminution of the forces within. All this was done very promptly, so that, in a few hours after he received the intelligence on which he was acting, he was drawing off secretly, at night, a column of six or eight thousand men, none of whom knew at all where they were going.
A night march.
He proceeded as rapidly as possible to the northward, and, when he arrived in the northern province, he contrived to get into the camp of Livius as secretly as he had got out from his own. Thus, of the two armies, the one where an accession of force was required was greatly strengthened at the expense of the other, without either of the Carthaginian generals having suspected the change.
Livius and Nero attack Hasdrubal.
Livius was rejoiced to get so opportune a re-enforcement. He recommended that the troops should all remain quietly in camp for a short time, until the newly-arrived troops could rest and recruit themselves a little after their rapid and fatiguing march; but Nero opposed this plan, and recommended an immediate battle. He knew the character of the men that he had brought, and he was, besides, unwilling to risk the dangers which might arise in his own camp, in southern Italy, by too long an absence from it. It was decided, accordingly, to attack Hasdrubal at once, and the signal for battle was given.
