Oaths, Military. The taking of the oath of fidelity to government and obedience to superior officers, was, among ancient armies, a very solemn affair. A whole corps took the oath together, and sometimes an entire army. The tribunes of every legion chose out one whom they thought the fittest person, and gave him a solemn oath at large, the substance of which was, that he should oblige himself to obey the commanders in all things to the utmost of his power, be ready to attend whenever they ordered his appearance, and never to leave the army but by their consent. After he had ended, the whole legion, passing one by one, every man, in short, swore to the same effect, crying, as he went by, Idem in me, “the same by me.” In modern times when so many other checks are used in maintaining discipline, the oath has become little more than a form. A recruit enlisting in the army or navy, or a volunteer enrolling himself, swears to be faithful to the government, and obedient to all or any of his superior officers. The members of a court-martial take an oath to try the cases brought before them justly, according to the evidence, to keep secret the finding and sentence of the court, until they shall be published by the proper authority, and to keep secret the votes or opinions given by the members individually. The judge-advocate swears that he will not reveal the individual opinions or votes of the members nor the sentence of the court to any but the proper authority. There is also an oath for the members and an oath for the recorder of a court of inquiry. The only other military oath is the common oath of a witness before a court-martial, to tell the truth, the whole truth, and nothing but the truth. See Appendix, [Articles of War].
Obedience (Fr. obéissance). Submission to the orders of a superior. The first principle which ought to be inculcated and impressed upon the mind of every officer and soldier is obedience to all lawful commands. It is the mainspring, the soul and essence of military duty. It is evident that if all officers and soldiers are to judge when an order is lawful and when not, the captious and mutinous would never be at loss for a plea to justify their insubordination. It is, therefore, an established principle, that unless an order is so manifestly against law that the question does not admit of dispute, the order must first be obeyed by the inferior, and he must subsequently seek such redress against his superior as the laws allow. If the inferior disputes the legality before obedience, error of judgment is never admitted in mitigation of the offense. The redress now afforded by the laws to inferiors is not, however, sufficient; for doubtful questions of the construction of statutes, instead of being referred to the Federal courts of law for their true exposition, have received variable expositions from the executive, and left the army in an unfortunate state of uncertainty as to the true meaning of certain laws; and this uncertainty has been most unfavorable to discipline. Again, while the punishment of death is meted to officers and soldiers for disobedience of lawful commands, the law does not protect officers and soldiers for obeying unlawful commands. Instances have occurred in the United States, where officers and soldiers have been subjected to vexatious prosecutions, simply for obeying orders according to their oath of office. Would it not be just if the law, instead of requiring officers and soldiers thus nicely to steer between Scylla and Charybdis, should hold the superior who gives an illegal order alone responsible for its execution?
Obedience to Orders. An unequivocal performance of the several duties which are directed to be discharged by military men. All officers and soldiers are to pay obedience to the lawful orders of their superior officers.
Obey, To. In a military sense, is without question or hesitation to conform zealously to all orders and instructions which are legally issued. It sometimes happens that individuals are called upon (by mistake, or from the exigency of the service) out of what is called the regular roster. In either case they must cheerfully obey, and after they have performed their duty they may remonstrate.
Obidos. A town of Portugal, in the province of Estremadura, situated on the Amaya, 45 miles northwest from Lisbon. An engagement took place here between the French and English in 1808.
Object. A word in military movements and evolutions, synonymous with point. Thus, in marching forward in line, etc., the guide of a squad, company, or battalion, must take two objects at least to fix his line of march by which the whole body is regulated. As he advances he selects succession objects or points to prolong the line.
Object. The mark aimed at in the fire of small-arms or artillery.
Objective-points. The point to be reached or gained by an army in executing a movement, has been termed the “objective-point.” There are two classes of objectives, viz., [natural] and [accidental]. The term geographical is frequently used to designate the first of these.
A natural objective may be an important position, strong naturally, or made so by fortifications, the possession of which gives control over a tract of country, and furnishes good points of support or good lines of defense for other military operations. Or, it may be a great business centre, or a capital of a country, the possession of which has the effect of discouraging the enemy and making him willing to sue for peace.
Accidental objectives are dependent upon the military operations which have for their object the destruction or disintegration of the enemy’s forces. These objectives are sometimes called “objective-points of manœuvre.” The position of the enemy determines their location. Thus, if the enemy’s forces are greatly scattered, or his front much extended, the central point of his position would be a good objective-point, since the possession of it would divide the enemy’s forces, and allow his detachments to be attacked separately. Or, if the enemy has his forces well supported, a good objective would be on that flank, the possession of which would allow his communications with his base to be threatened. It is well to remark that the term “point” used in this connection is not to be considered merely in its geometrical sense, but is used to apply to the object which the army desires to attain, whether it be a position, a place, a line, or even a section of country.—Prof. J. B. Wheeler.
