Both in numbers and percentages, Southern conscripts outnumbered Union conscripts considerably:
That statement outside of the timeline context and necessity involved is meaningless.
The Confederacy was fighting a war of survival, the North was fighting a war of subjugation. I give defenders a lot more leeway morally than I do attackers.
The total numbers serving the Union army were around 2.5 million, so there were far fewer conscripts in the North vs. Confederates.
And again, out of context. The North's population was 4 times the size of the South, and that was before they dragooned the Irish off the boats.
This nation drafted men for war, even when our own survival as a nation was not under threat.
