But should it happen--which fortunately is not a reasonable surmise--that the objects of this year's campaign should not be attained, we consider that the Southern confederacy exists only in pretence. Should its ports be to-day opened, should our armies fall back to their primary bases of operation, should European Powers formally declare that a slave republic exists, yet the new nation would be practically a nonentity. Does any one suppose that the United States would yield Kentucky, Tennessee, Missouri, Arkansas, New Orleans, and the Mississippi; that the freemen of Western Virginia would be forsaken; that Fortress Monroe and Port Royal would be abandoned? How long would a nation so surrounded, so intersected, exist, or how could it achieve any prosperity, character, and stability? Constant war, in the effort to expand and perfect its borders, would be its necessity; but such a necessity would be its destruction. There is no possibility of compromise or arrangement in the contest in which we are engaged, except with the parallel of the Potomac and the Ohio as the dividing border; but such an arrangement is impossible; entire reconquest becomes the imperative; it may be delayed, our present hopes may be disappointed, but the march of our armies thus far has trodden out the life from the Southern attempt at independence, and any future existence it may have will be merely muscular paroxysms--not the steady, regular, automatic movements of freedom and spontaneity. Any notice of the operations of our armies would be incomplete without tributes to the ability of commanders and the valor of our soldiers. In no previous period of the war have these been more strikingly exemplified. The capacity of man to endure and his ability to exert himself continuously without exhausting his energy, are very wonderful. The reader of military history is constantly struck with this, in perusing accounts of sieges and marches and battles. War is always accompanied with a host of terrors--exposures to heat, cold, and tempests, marches through swamps and snows, suffering by hunger and thirst and fatigue, lying with bleeding wounds for days and nights between the lines of friends and foes, toil, danger, privation, pain, in every form. But among the memorable campaigns in the history of war, none is more marked for its incessant activity and the cheerful alacrity with which every hardship was endured, than that in which our army marched from the Rapidan to the James. From Georgia, too, we have similar accounts of difficulties met only to be surmounted. Heaven bless our gallant soldiers everywhere! A nation's hopes and prayers are with them. May they know the soldier's dearest delight--victory!
