Wait, what? Deportation? Isn't that tacitly acknowledging them as a foreign country? You cannot "deport" someone to the same country. And what is the precedent for deporting someone who is an actual US citizen?
On the other hand, if Lincoln regarded them as US states in a condition of rebellion, is this not akin to tossing someone to a dangerous mob?
What is the legal basis for doing that? How is this legal any sort of way?
Deportation was not the word used by the Lincoln administration. Their order, as transmitted through Stanton, was to "send C. L. Vallandigham under secure guard to the headquarters of General Rosecrans to be put by him beyond our military lines and in case of his return within our lines he be arrested and kept in close custody for the term specified in his sentence."
