EVACUATE, in military history, a term made use of in the articles of capitulation granted to the besieged at the time they surrender to the besiegers; and is the same as quitting a place.
EVENT, Fr. Vent. This word is particularly applicable to the vent or cavity which is left in cannon, or other fire arms, after they have been proved and found defective. The vent is sometimes round and sometimes long. Vents are frequently so exiguous, that they appear like the lines of a small fibre, through which water will ooze, and smoke evaporate. These pieces, whether of ordnance, or of musquetry, are of course rejected.
EVIDENCE, a declaration made viva voce of what any person knows of his own knowlege relative to the matter in question. Military men are obliged to attend and give evidence before courts-martial, without any expence to the prosecutor, or prisoner.
Hearsay Evidence, the declaration of what one has heard from others. As in all other courts of ordinary judicature, this species of evidence is not admissible in courts-martial.
EVOCATI, were a class of soldiers among the Romans, who, after having served their full time in the army, entered as volunteers to accompany some favorite general. Hence they were likewise called emeriti and beneficiarii.
EVOCATION. A religious ceremony which was always observed among the Romans, at the commencement of a siege, wherein they solemnly called upon the gods and goddesses of the place to forsake it, and come over to them. When any place surrendered, they always took it for granted, that their prayer had been heard, and that the Dii Penates, or the household gods of the place had come over to them.
EVOLUTION, in the art of war, the motion made by a body of troops, when they are obliged to change their form and disposition, in order to preserve a post, occupy another, to attack an enemy with more advantage, or to be in a condition of defending themselves the better. That evolution is best, which, with a given number of men, may be executed in the least space, and consequently in the least time possible.
Evolution of the moderns, is a change of position, which has always for its object either offence or defence. The essentials in the performance of an evolution are, order, directness, precision, and the greatest possible rapidity.
Evolutions may be divided into two classes, the simple and the compound; simple evolutions are those which consist in simple movements, which do not alter the shape or figure of the battalion, but merely afford a more or less extended front or depth, keep it more or less closed to its flanks or centre, turn its aspect to flank or rear, or break it into divisions, subdivisions, sections, or files, in order that it may unfold itself, or defile and resume its proper front or order of battle. All the various ways of defiling, forming line, opening to right and left, closing or deploying, doubling the ranks or files, or changing front upon either of the flanks by conversion, are called simple evolution.
