It may either, first, by means of a very rigorous police, and in spite of the whole bent of the interest, genius, and inclinations of the people, enforce the practice of military exercises, and oblige either all the citizens of the military age, or a certain number of them, to join in some measure the trade of a soldier to whatever other trade or profession they may happen to carry on.
Or, secondly, by maintaining and employing a certain number of citizens in the constant practice of military exercises, it may render the trade of a soldier a particular trade, separate and distinct from all others.
If the state has recourse to the first of those two expedients, its military force is said to consist in a militia;if to the second, it is said to consist in a standing army.The practice of military exercises is the sole or principal occupation of the soldiers of a standing army, and the maintenance or pay which the state affords them is the principal and ordinary fund of their subsistence.The practice of military exercises is only the occasional occupation of the soldiers of a militia, and they derive the principal and ordinary fund of their subsistence from some other occupation.In a militia, the character of the labourer, artificer, or tradesman, predominates over that of the soldier; in a standing army, that of the soldier predominates over every other character: and in this distinction seems to consist the essential difference between those two different species of military force.
Militias have been of several different kinds.In some countries the citizens destined for defending the states seem to have been exercised only, without being, if I may say so, regimented; that is, without being divided into separate and distinct bodies of troops, each of which performed its exercises under its own proper and permanent officers.In the republics of ancient Greece and Rome, each citizen, as long as he remained at home, seems to have practised his exercises either separately and independently, or with such of his equals as he liked best, and not to have been attached to any particular body of troops till he was actually called upon to take the field.In other countries, the militia has not only been exercised, but regimented.In England, in Switzerland, and, I believe, in every other country of modern Europe where any imperfect military force of this kind has been established, every militiaman is, even in time of peace, attached to a particular body of troops, which performs its exercises under its own proper and permanent officers.
Before the invention of firearms, that army was superior in which the soldiers had, each individually, the greatest skill and dexterity in the use of their arms.Strength and agility of body were of the highest consequence, and commonly determined the state of battles.But this skill and dexterity in the use of their arms could be acquired only, in the same manner as fencing is at present, by practising, not in great bodies, but each man separately, in a particular school, under a particular master, or with his own particular equals and companions.Since the invention of firearms, strength and agility of body, or even extraordinary dexterity and skill in the use of arms, though they are far from being of no consequence, are, however, of less consequence.The nature of the weapon, though it by no means puts the awkward upon a level with the skilful, puts him more nearly so than he ever was before.All the dexterity and skill, it is supposed, which are necessary for using it, can be well enough acquired by practising in great bodies.
Regularity, order, and prompt obedience to command are qualities which, in modern armies, are of more importance towards determining the fate of battles than the dexterity and skill of the soldiers in the use of their arms.But the noise of firearms, the smoke, and the invisible death to which every man feels himself every moment exposed as soon as he comes within cannon-shot, and frequently a long time before the battle can be well said to be engaged, must render it very difficult to maintain any considerable degree of this regularity, order, and prompt obedience, even in the beginning of a modern battle.In an ancient battle there was no noise but what arose from the human voice; there was no smoke, there was no invisible cause of wounds or death.Every man, till some mortal weapon actually did approach him, saw clearly that no such weapon was near him.In these circumstances, and among troops who had some confidence in their own skill and dexterity in the use of their arms, it must have been a good deal less difficult to preserve some degree regularity and order, not only in the beginning, but through the whole progress of an ancient battle, and till one of the two armies was fairly defeated.But the habits of regularity, order, and prompt obedience to command can be acquired only by troops which are exercised in great bodies.
A militia, however, in whatever manner it may be either disciplined or exercised, must always be much inferior to a well-disciplined and well-exercised standing army.
The soldiers who are exercised only once a week, or once a month, can never be so expert in the use of their arms as those who are exercised every day, or every other day; and though this circumstance may not be of so much consequence in modern as it was in ancient times, yet the acknowledged superiority of the Prussian troops, owing, it is said, very much to their superior expertness in their exercise, may satisfy us that it is, even at this day, of very considerable consequence.
