Having Grown up in Maryland around all those battlefields, I spent some time there. Antietam is fucking crazy how anyone could think they could pull that off.
But Gettysburg, that's something else. I always tell people to go see that, see what the fuck went down, and the outright beat down the south received, and the only reason the South had any success was the fact they had several West Point Generals in their stead, include Stonewall and Lee.
Years back I had read this book on the generals.

It was not bad. I am sure Brandon can find it for a few $$ on half.com
