Connecticut’s Hartford Times of November 7, 1860, after referring to the danger that the Southern States would “form a separate confederacy, and retire peaceably from the Union,” proceeds to say “If they do decide and act, it will be useless to attempt any coercive measures to keep them within the voluntary co-partnership of States . . . We can never force sovereign States to remain in the Union when they desire to go out, without bringing upon our country the shocking evils of civil war, under which the Republic could not, of course, long exist.”
The misunderstanding of “treason” is noted in the text below, but its actual definition is found in Article II, Section 3 of the United States Constitution: “Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort.” It is clear then, whoever waged war upon the several seceding States (them) was guilty of treason. Outgoing President James Buchanan understood this and admitted no authority to wage war against a State, as did his Attorney-General.
A Civil War in the North?
“Prominent supporters of Mr. Lincoln asserted that “secession is treason, and must be treated by the government as treason,” and that “the government has the right and the power to compel obedience.” A considerable number of Republicans, while they emphatically denied the right of secession, questioned the policy of forcibly preventing it. They held, that, if an undoubted majority of the adult population of any State deliberately pronounced for separation, the rest of the States, though they might legally compel that State to remain, would do better to assemble in national convention, and acquiesce in her departure from the Union. Withdrawal under these sanctions is the only secession ever deemed valid or permissible by any number of the supporters of Mr. Lincoln. Many who had voted against him also concurred in this view.
Some of the opponents of the President-elect denied the right of secession, but claimed there was no constitutional remedy against it. The greater part held that the recusant States were theoretically if not practically right; that the United States was simply a confederation of sovereign States, any one of which possessed a constitutional right to withdraw whenever it should consider the arrangement no longer profitable. They deemed an attempt to coerce a State, in order to vindicate the supreme authority of the Federal Government and to preserve the territorial integrity of the Union, to be both illegal and useless.
The opponents of Mr. Lincoln . . . asserted that the Southern people had abundant provocation for their . . . conduct. They . . . declared that the conservatives of the North would never consent to coercion; adding the not infrequent menace, that, “if war is to be waged, that war will be fought in the North.”
