Would you have volunteered to fight in the American Civil War?

Considering my ancestors weren't in the US at the time and that I do have ancestors who had to hightail it to Canada after the Tax Revolt of 1775-83, probably not.  Might have signed up to defend Canada in case Seward's cockamamie plan to restore the Union by invading Canada ever got past the lame idea stage.

1....preferably artillery or intelligence.

Grant turned a number of the heavy artillery regiments defending Washington into infantry because he needed the latter more than the former.  It proved quite a shock to those who thought they'd found a relatively safe berth to serve in.

I had two great grandfather's who fought in that war, one on each side (the one who fought on the Union side taking two bullets, which he carried to his grave some 70 years later). Obviously where I lived would have a big impact, but I would like to believe that if I lived in the South, I would have had enough good conscience, and character, to have fled and taken up arms against it. Its enterprise and objects were truly evil in every respect.

If you truly had felt that strongly about slavery, you probably would have left the South well before the war.
