The use of the Grecian spear, the Roman sword, or the modern bayonet, might be acquired with comparative ease. But nothing short of the daily exercise of years could train the man-at-arms to support his ponderous panoply, and manage his unwieldy weapon. Throughout Europe this most important branch of war became a separate profession. Beyond the Alps, indeed, though a profession, it was not generally a trade. It was the duty and the amusement of a large class of country gentlemen. It was the service by which they held their lands, and the diversion by which, in the absence of mental resources, they beguiled their leisure. But in the Northern States of Italy, as we have already remarked, the growing power of the cities, where it had not exterminated this order of men, had completely changed their habits. Here, therefore, the practice of employing mercenaries became universal, at a time when it was almost unknown in other countries. When war becomes the trade of a separate class, the least dangerous course left to a government is to force that class into a standing army. It is scarcely possible, that men can pass their lives in the service of one State, without feeling some interest in its greatness. Its victories are their victories. Its defeats are their defeats. The contract loses something of its mercantile character. The services of the soldier are considered as the effects of patriotic zeal, his pay as the tribute of national gratitude. To betray the power which employs him, to be even remiss in its service, are in his eyes the most atrocious and degrading of crimes. When the princes and commonwealths of Italy began to use hired troops, their wisest course would have been to form separate military establishments. Unhappily this was not done. The mercenary warriors of the Peninsula, instead of being attached to the service of different powers, were regarded as the common property of all. The connection between the State and its defenders was reduced to the most simple and naked traffic. The adventurer brought his horse, his weapons, his strength, and his experience, into the market. Whether the King of Naples or the Duke of Milan, the Pope or the Signory of Florence, struck the bargain, was to him a matter of perfect indifference. He was for the highest wages and the longest term. When the campaign for which he had contracted was finished, there was neither law nor punctilio to prevent him from instantly turning his arms against his late masters. The soldier was altogether disjoined from the citizen and from the subject.
