“The South was fighting to take slavery out of the Union,
and the North was fighting to keep it in the Union;
the South fighting to get it beyond the limits of the
United States Constitution, and the North fighting to
retain it within those limits; the South fighting for new
guarantees, and the North fighting for the old
guarantees;--both despising the Negro, both insulting the Negro."
