So that, while this proviso was, publicly, the Pandora's box which filled the Union with evil, and while it was to Mr. Calhoun and his friends the theme of endless deprecation, it was secretly cherished as a means of keeping up discord, and forcing the issue between the North and the South. Mr. Calhoun then proceeds to the serious question of disunion, and of the manner in which the issue could be forced.
"This brings up the question, how can it be so met, without resorting to the dissolution of the Union? I say without its dissolution, for, in my opinion, a high and sacred regard for the constitution, as well as the dictates of wisdom, make it our duty in this case, as well as all others, not to resort to, or even to look to that extreme remedy, until all others have failed, and then only in defence of our liberty and safety. There is, in my opinion, but one way in which it can be met; and that is the one indicated in my letter to Mr. ——, and to which you allude in yours to me, viz., by retaliation. Why I think so, I shall now proceed to explain."
Then follows an argument to justify retaliation, by representing the constitution as containing provisions, he calls them stipulations, some in favor of the slaveholding, and some in favor of the non-slaveholding States, and the breach of any of which, on one side, authorizes a retaliation on the other; and then declaring that Pennsylvania, and other States, have violated the provision in favor of the slave States in obstructing the recovery of fugitive slaves, he proceeds to explain his remedy—saying:
"There is and can be but one remedy short of disunion, and that is to retaliate on our part, by refusing to fulfil the stipulations in their favor, or such as we may select, as the most efficient. Among these, the right of their ships and commerce to enter and depart from our ports is the most effectual, and can be enforced. That the refusal on their part would justify us to refuse to fulfil on our part those in their favor, is too clear to admit of argument. That it would be effectual in compelling them to fulfil those in our favor can hardly be doubted, when the immense profit they make by trade and navigation out of us is regarded; and also the advantages we would derive from the direct trade it would establish between the rest of the world and our ports."
Retaliation by closing the ports of the State against the commerce of the offending State: and this called a constitutional remedy, and a remedy short of disunion. It is, on the contrary, a flagrant breach of the constitution, and disunion itself, and that at the very point which caused the Union to be formed. Every one acquainted with the history of the formation of the federal constitution, knows that it grew out of the single question of commerce—the necessity of its regulation between the States to prevent them from harassing each other, and with foreign nations to prevent State rivalries for foreign trade. To stop the trade with any State is, therefore, to break the Union with that State; and to give any advantage to a foreign nation over a State, would be to break the constitution again in the fundamental article of its formation; and this is what the retaliatory remedy of commercial non-intercourse arrives at—a double breach of the constitution—one to the prejudice of sister States, the other in favor of foreign nations. For immediately upon this retaliation upon a State, and as a consequence of it, a great foreign trade is to grow up with all the world. The letter proceeds with further instructions upon the manner of executing the retaliation:
"My impression is, that it should be restricted to sea-going vessels, which would leave open the trade of the valley of the Mississippi to New Orleans by river, and to the other Southern cities by railroad; and tend thereby to detach the North-western from the North-eastern States."
This discloses a further feature in the plan of forcing the issue. The North-eastern States were to be excluded from Southern maritime commerce: the North-western States were to be admitted to it by railroad, and also allowed to reach New Orleans by the Mississippi River. And this discrimination in favor of the North-western States was for the purpose of detaching them from the North-east. Detach is the word. And that word signifies to separate, disengage, disunite, part from: so that the scheme of disunion contemplated the inclusion of the North-western States in the Southern division. The State of Missouri was one of the principal of these States, and great efforts were made to gain her over, and to beat down Senator Benton who was an obstacle to that design. The letter concludes by pointing out the only difficulty in the execution of this plan, and showing how to surmount it.
"There is but one practical difficulty in the way; and that is, to give it force, it will require the co-operation of all the slave-holding States lying on the Atlantic Gulf. Without that, it would be ineffective. To get that is the great point, and for that purpose a convention of the Southern States is indispensable. Let that be called, and let it adopt measures to bring about the co-operation, and I would underwrite for the rest. The non-slaveholding States would be compelled to observe the stipulations of the constitution in our favor, or abandon their trade with us, or to take measures to coerce us, which would throw on them the responsibility of dissolving the Union. Which they would choose, I do not think doubtful. Their unbounded avarice would, in the end, control them. Let a convention be called—let it recommend to the slaveholding States to take the course advised, giving, say one year's notice, before the acts of the several States should go into effect, and the issue would fairly be made up, and our safety and triumph certain."
This the only difficulty—the want of a co-operation of all the Southern Atlantic States; and to surmount that, the indispensability of a convention of the Southern States is fully declared. This was going back to the starting point—to the year 1835—when Mr. Calhoun first took up the slavery agitation in the Senate, and when a convention of the slaveholding States was as much demanded then as now, and that twelve years before the Wilmot Proviso—twelve years before the Pennsylvania unfriendly legislation—twelve years before the insult and outrage to the South, in not permitting them to carry their local laws with them to the territories, for the protection of their slave property. A call of a Southern convention was as much demanded then as now; and such conventions often actually attained: but without accomplishing the object of the prime mover. No step could be got to be taken in those conventions towards dividing and sectionalizing the States, and after a vain reliance upon them for seventeen years, a new method has been fallen upon: and this confidential letter from Mr. Calhoun to a member of the Alabama legislature of 1847, has come to light, to furnish the key which unlocks his whole system of slavery agitation which he commenced in the year 1835. That system was to force issues upon the North under the pretext of self-defence, and to sectionalize the South, preparatory to disunion, through the instrumentality of sectional conventions, composed wholly of delegates from the slaveholding States. Failing in that scheme of accomplishing the purpose, a new one was fallen upon, which will disclose itself in its proper place.
