As Lincoln never accepted the independence of those States which had withdrawn to form a more perfect union, his actions can be judged in a light illuminated by the United States Constitution and the strictly enumerated powers delegated to his branch. The crime of treason is clearly defined in Article III, Section 3 of that document: “Treason against the United States shall consist only in levying War against Them, or in adhering to their Enemies, giving them Aid and Comfort.” Note the emphasis on “Them,” individually. By commencing hostilities against South Carolina and other States, he violated Section III, Article 3.

Lincoln Acts Alone and By Decree
“By his selective use of the American past, his devotion of the nation to an abstract proposition, and his expansive vision of America’s role in the world, Lincoln undermined the old federated republic. He rewrote the history of the founding, and then waged total war to see his version of the past vindicated by success.
But in the course of subjugating the “insurrectionary” and “revolutionary” combination in the South, and in creating a unitary nation, he also compromised the integrity of the Presidency as a Constitutional office, first by invading the powers of the other two branches and then by assuming further powers nowhere mentioned in the Constitution.
He may have claimed that in the midst of an unprecedented national crisis necessity knew no law, but the Constitution in fact recognized the possibility of emergencies and delegated necessary and appropriate powers to the President and Congress. As historian Clinton Rossiter wrote: “The Constitution looks to the maintenance of the pattern of regular government in even the most stringent of crises.” But Lincoln acted alone.
From the fall of Fort Sumter in April, 1861, to the convening of a special session of Congress in July of 1861, President Lincoln ruled by decree, and on his own initiative and authority he commenced hostilities against the Confederacy. For 11 weeks that spring and early summer, Lincoln exercised dictatorial powers, combining them within his person the executive, legislative and judicial powers of the national government in Washington.
In his inaugural speech in March he had announced that the union had the right and the will to preserve itself. He promised to secure federal property in the seceded States, to collect all duties and to deliver the mails – all steps short of invasion but intended nonetheless to subjugate the South.
He assumed so-called “war-powers” – a familiar feature of the modern Presidency, but them a novelty – and proceeded to wage war without a declaration from Congress. The oft-raised concern that Lincoln could not have proceeded otherwise and still have preserved the Union should not obscure the problem of the means he resorted to.
The Constitutionality of his acts cannot be, as one historian claimed, “a rather minor issue,” for at stake was the integrity of free institutions.”
