Am I wrong in thinking that his death was one of the biggest factors in their eventual defeat? Also in Rebel Yell by S. C. Gwynne it is said of Ewell that "he declined to press his advantage, which meant the Union forces ended up holding the key high-ground positions south of town, which eventually included Cemetery Ridge, Little Round Top, and Big Round Top. Jackson, in a similar situation, likely would have taken that ground". Is there any truth to this? I feel like Ewell was forced to fill shoes few could fill.
While Jackson may have been a very talented and capable commander, structural issues doomed the confederacy in the long run. Union advantages in food supply, manpower, transportation, and manufacturing were pretty insurmountable. Were it not for McLellan's incompetence, the war could have been won during 1862's peninsula campaign, a moment when Jackson was very much alive. From my studies of the Civil War it seems like the myth of Stonewall Jackson is a component of the lost cause myth, and turning him into a mystical, triumphant doomed figure allowed former confederates and modern day confederate sympathizers to avoid reckoning with the overwhelming long-term superiority of the Union army and the foolhardiness of fighting a war with the North
