Much has been made of the shooting ability of the Southern good ole boys. Much has been made of the north having the advantage of/in industry. A further thought. The incoming immigrants and already solidly entrenched immigrant communities. For the north, I'll not deny we had the industry and resources advantage. How about addressing the ethnic variable ? We did a good job of enlisting the incoming Irish, also some of the units enlisted in the upper midwest were heavily weighted with Nordic men. Some of the norths best fighting units were comprised of these two sources. Your thoughts ? Play nice please !
