War between the States, in the first period of their separate existence, would be accompanied with much greater distresses than it commonly is in those countries where regular military establishments have long obtained. The disciplined armies always kept on foot on the continent of Europe, though they bear a malignant aspect to liberty and economy, have, notwithstanding, been productive of the signal advantage of rendering sudden conquests impracticable, and of preventing that rapid desolation which used to mark the progress of war prior to their introduction. The art of fortification has contributed to the same ends. The nations of Europe are encircled with chains of fortified places, which mutually obstruct invasion. Campaigns are wasted in reducing two or three frontier garrisons, to gain admittance into an enemy’s country. Similar impediments occur at every step, to exhaust the strength and delay the progress of an invader. Formerly, an invading army would penetrate into the heart of a neighboring country almost as soon as intelligence of its approach could be received; but now a comparatively small force of disciplined troops, acting on the defensive, with the aid of posts, is able to impede, and finally to frustrate, the enterprises of one much more considerable. The history of war, in that quarter of the globe, is no longer a history of nations subdued and empires overturned, but of towns taken and retaken; of battles that decide nothing; of retreats more beneficial than victories; of much effort and little acquisition. In this country the scene would be altogether reversed. The jealousy of military establishments would postpone them as long as possible. The want of fortifications, leaving the frontiers of one state open to another, would facilitate inroads. The populous States would, with little difficulty, overrun their less populous neighbors. Conquests would be as easy to be made as difficult to be retained. War, therefore, would be desultory and predatory. PLUNDER and devastation ever march in the train of irregulars. The calamities of individuals would make the principal figure in the events which would characterize our military exploits. This picture is not too highly wrought; though, I confess, it would not long remain a just one. Safety from external danger is the most powerful director of national conduct. Even the ardent love of liberty will, after a time, give way to its dictates. The violent destruction of life and property incident to war, the continual effort and alarm attendant on a state of continual danger, will compel nations the most attached to liberty to resort for repose and security to institutions which have a tendency to destroy their civil and political rights. To be more safe, they at length become willing to run the risk of being less free.
