Against this Rebellion we wage war. It is our determination, as it is our duty, to crush it; and this will be done. Nor am I disturbed by any success which the Rebels may seem to obtain. The ancient Roman, who, confident in the destiny of the Republic, bought the field on which the conquering Hannibal was encamped, is a fit example for us. I would not have less trust than his. The Rebel States are our fields. The region now contested by the Rebels belongs to the United States by every tie of government and of right. Some of it has been bought with our money, while all of it, with its rivers, harbors, and extensive coast, has become essential to our business in peace and to our defence in war. Union is a geographical, economical, commercial, political, military, and (if I may so say) even a fluvial necessity. Without union, peace on this continent is impossible; but life without peace is impossible also. Only by crushing this Rebellion can union and peace be restored. Let this be seen in its reality, and who can hesitate? If this were done instantly, without further contest, then, besides all the countless advantages of every kind obtained by such restoration, two special goods will be accomplished,--one political, and the other moral as well as political. First, the pretended right of secession, with the whole pestilent extravagance of State sovereignty, supplying the machinery for this Rebellion, and affording a delusive cover for treason, will be trampled out, never again to disturb the majestic unity of the Republic; and, secondly, the unrighteous attempt to organize a new confederacy, solely for the sake of Slavery, and with Slavery as its corner-stone, will be overthrown. These two pretensions, one so shocking to our reason and the other so shocking to our moral nature, will disappear forever. And with their disappearance will date a new epoch, the beginning of a grander age. If by any accident the Rebellion should prevail, then, just in proportion to its triumph, through concession on our part or successful force on the other part, will the Union be impaired and peace be impossible. Therefore in the name of the Union and for the sake of peace are you summoned to the work. * * * * *
