Infamous Behavior. In the British service a term peculiarly applicable to military life when it is affected by dishonorable conduct; on conviction of which, an officer is ordered to be cashiered. Infamy may be attached to an officer or soldier in a variety of ways; and some countries are more tenacious than others on this head. Among European nations it has always been deemed infamous and disgraceful to abandon the field of action or to desert the colors. In Germany a mark of infamy was attached to the character of every man who was found guilty of misbehavior before the enemy. Among the Romans it was considered as infamous and disgraceful to be taken prisoner, and a Roman soldier was impressed with the idea that he must either conquer or die on the field. There are various occasions in which the conduct of an officer may render him unworthy of the situation he fills, such as cheating at play, taking unfair advantages of youth, imposing upon the credulity or confidence of a tradesman, habitual drunkenness, flagrant breaches of hospitality, etc.

Infantry (Lat. infans, “child,” or “servant,” applied to servants who went on foot, and infanterie, to foot-soldiers generally). Is that portion of a military establishment using small-arms and equipped for marching and fighting on foot, in contradistinction to artillery and cavalry. It is the oldest of the “three arms” into which armies are conventionally divided; was the favorite of the Greeks, the Gauls, the Germans, and the Franks, and was that mainly with which Rome conquered the world. Under Grecian and Roman civilization it attained pre-eminence as the arm of battle, but fell into contempt and comparative desuetude early in the Middle Ages, and did not emerge from that obscurity till the decline of the feudal system. It was first revived by the Swiss, who, armed with the pike, withstood the most famous chivalry of Europe. Afterwards the Spanish infantry, armed with the musket, and led by Alva and the Duke of Parma, Cortez and Pizarro, became the terror of two continents. The other states of Europe were not slow in learning the lesson. Infantry steadily increased in power and importance from the first years of the 14th century, and is now recognized as constituting the principal strength of military organizations. This importance results from the fact that it can be used everywhere, “in mountains or on plains, in woody or open countries, in cities or in fields, on rivers or at sea, in the redoubt or in the attack on the breach.” It is the self-sustaining arm in the field of battle, and is, moreover, less expensive, man for man, than its auxiliaries.
