When war becomes the trade of a separate class the least dangerous course left to a government is to form 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.
The natural consequences followed. Left to the conduct of men who neither loved those whom they defended, nor hated those whom they opposed, who were often bound by stronger ties to the army against which they fought than to the State which they served, who lost by the termination of the conflict, and gained by its prolongation, war completely changed its character. Every man came into the field of battle impressed with the knowledge, that, in a few days, he might be taking the pay of the power against which he was then employed, and fighting by the side of his enemies against his associates.
