Not just Nat. Pacifists who joined state militia to fight for freedom for slaves had no experience with guns or even fist fights. They were soft and could not pull the trigger when they had Johnny Reb in their sights. The result was that in the early stages of the war the North lost an extremely large number of volunteers and had to draft immigrants.
My immigrant ancestors were the ones drafted. I am embarrassed to admit that I came across a cringing letter in Ancestry.com from a relative of mine trying to get out of the draft. A NYer - a notoriously Copperhead Democrat city.
