The American Civil War or How the South got it’s ass kicked.
4 to 1 odds in manpower. It should have gotten it's @$$ kicked four years earlier, but I think for most men of the North, their heart was not in it. I certainly think this is true for McClellan.
The men of the South were fighting for their homeland against the invaders who were just fighting for Washington DC to subjugate everyone.
And here we sit today with Washington DC still subjugating everyone.
