“the U.S. was considered by the confederacy to be a foreign country, and imports of slaves from there was specifically protected.”
Yea, Just a bunch of god loving, anti-slave Union people that gave life and limb to free the slaves.....I notice you never mention the drafts.
Are you not aware that the confederacy instituted conscription over a year before the Union did? As well as forcibly extending enlistments for the duration of the war?
