Now we love today to look back at the American Civil War and because of this disparity of resources that I've already told you about think that the end of the war was inevitable and that the north would win.
Not so fast. Especially when you get the Gettysburg Campaign in 1863.
Will in the north is eroding just like the Confederates are hoping for because the cost of blood of this war is unprecedented.
You can take any major Civil War battle--you name it--Bull Run, Antietam, Gettysburg, Chancellorsville. You name the battle. That battle by itself [one of the aforementioned] one, two, three day event exceeds all the casualties the United States had in the American Revolution, The war of 1812, and the Mexican War combined.
And yet that will continued for almost another two years and kept armies in the field significantly larger than Confederate ones up until the inevitable victory.
