Actually Mac, I grew up thinking Lincoln freed the slaves and was a Great President. I thought the war was about slavery.
8 or 10 years later I have learned different. Yes the War Was unneceesary, the North did not have to prepare for War upon the South and force the South into firing on them.
Yes it was immoral, as more Union commanders allowed their men to violate Southern Women, Black and White, than not.
No one who has studied the War can adjudicate a moral reason for the Union actions, not can the adjudicat a legal reason for their reasons.
I learned this on my own from books and sharing information on this message board.
