You don't see the difference. The southerners were brave and proud and knew how to fight. Modern liberals are weak, decadent and lack a moral compass. They are "all hat and no cattle."
BTW--most military historians believe that the outcome of the American civl war was a foregone conclusion. Even if Stonewall lived, it utlimately would have been of little consequence.
No, I'm afraid that you don't see the point. The Southerners had such a low opinion of the fighting capabilities of the Yankees that they felt that their secession would be an easy fight and a foregone conclusion.
The North thought that they had the manpower and the equipment to easily subdue the rebellion and that poor Southerners would not fight for the blueblood aristocracy.
Both were wrong ... and, if Generals Lee, Longstreet, and Johnston had been different people, the Confederate Army would have taken to the hills to fight for years in a guerilla war against the occupying North.
Again, I would give you the warning ... things rarely turn out as expected.
Piffle ... I have read none who thought it a foregone conclusion until after Gettysburg, and a number who believed that there was a chance for Southern victory until the siege of Petersburg.
A live Stonewall Jackson at Gettysburg .. instead of Ewell and Early .. would have probably completed changed the first day results. Atlanta held until after the Federal elections may have resulted in a McClellan victory. Guerilla war after Appomattox may have led to war-/occupation-weariness on the part of the North and withdrawal and defacto victory for the Confederacy.
Again, I know of no historian who has taken a position that a Southern defeat was a foregone conclusion until well into the conflict, and very few who would have written off the South until after Gettysburg and the fall of Vicksburg.
