Actually it wasn't even issued. When I read "Lincoln and Chief Justice Taney", I took the chance to email James Simon and tell him how much I enjoyed his book. I also asked him if he had found any evidence of any attempt to arrest Taney by Lincoln or anyone else. His answer was a definitive 'no', he had found no evidence at all supporting the claim.
I did say “may.”
The claims I’ve seen have been secondary reports from purported participants decades after the events in question.
Nothing resembling actual documentary evidence has been found.
That said, a great many Americans of southern sympathies were indisputably committing treason, by the Constitution’s definition, during the War.
If the CSA was indeed a separate nation, as they claimed, then they were giving aid and comfort to their country’s enemy, to the extent in many cases of burning bridges, killing soldiers, etc.
