In order to have Stonewall Jackson at Gettysburg, we have to practically assume that there is no accidental shooting of Jackson, and also assume that there are other significant butterflies between May and July 1863.
The question i am asking is whether or not Stonewall Jackson, on the third day/July 3, could pull off a successful charge like Pickett couldn't?
Could Jackson ensure victory, or would he perhaps go down like Armistead in the charge?
