Why were the leaders of the insurrection of 1861-1865 in th U.S., the Civil War, not prosecuted for treason. After all, John Brown had been convicted of treason in Virginia in the 1850’s and hanged. Numerous rebellious slaves had been hanged. Native Americans who rose in rebellion in New Ulm, Minnesota the civil war were hanged as a result. Meanwhile, the leaders of the Confederacy went home to die peacefully in their beds, even though hundreds of thousands had died in the rebellion that they started. How did this happen?
Spirit of reconciliation.
Jefferson Davis was imprisoned for a time, if that counts. But stringing up someone as widely beloved as R.E.Lee would have just started another insurrection.
Davis and Lee were also stripped of their citizenship. It was a largely symbolic gesture back then, but some accounts I’ve read said that Lee was particularly bitter about it.
There was a significant portion of the Republican party that wanted to hang all of the major Confederate leaders, but fortunately cooler heads prevailed.
After Lincoln’s assassination, Andrew Johnson gave out a lot of pardons to former Confederates.
It would have been too difficult for the country to go through a “Reign of Terror” type Reconstruction.
Eventually, the former VP of the Confederacy ended up back in Congress.
John Brown was, I believe, tried for treason against the State of Virginia, not the U.S.
In any event, all the people mentioned in the OP were also personally involved in violent acts that resulted in deaths. The leaders of the Confederacy were gentlemen who debated policy in statehouses and voted and signed declarations of their intent to secede.
I am not justifying the differences in the responses to their actions. That is however, the way the world tends to work.
RTA’s comment is also true. There were calls among the Radical Republicans for treason trials, but even among that group, the general feeling was that punishing the peoples of the rebellious states with Federal oversight was more productive than hanging the leaders and causing more resentment.
One Confederate leader left the country. Secretary of State Judah P. Benjamin escaped to England where he set up a successful law practice. He may have suspected at the time that reconciliation might stop with Protostants.
They did hang Major Henry Wirz, the superintendent of the infamous Andersonville prison camp, although he was found guilty of murder rather than treason.
It refers to the perception of them that was most likely held by the political leaders in the North at the time. It was a mildly ironic point made in contrast to the people mentioned in the OP who were executed, none of whom would have been held to be gentlemen by the authorities responsible for apprehending, trying, or executing them.
Another factor in why the Federal authorities did not institute treason trials against Confederate figures was that convictions were not a sure thing. After sending hundreds of thousands to their deaths and spending huge amounts of money to crush secession, the Feds did not want to risk having a court find that the Confederate leaders did in fact have a constitutional right to secede.
