I already gave the board my reasoning behind the Confederate underperformance, so accept it or don't accept it. I'm not a military strategist and neither are you, and neither is any other blogger. I simply use eco data to come with my assessments, and you and other people seem to come up with your assessments on how you feel and emotions.
Before I go any further let's get some straight in our thinking: we are critiquing 19th century military strategy and capability, so we should take everything we say with a grain of salt. We are armchair quarterbacking on the internet, so people should not take it too serious because hindsight is always 20/20.
I think the Union strategy is worth discussing more than the Confederate strategy. This is a copy and paste from some of my post(s).
McClellan had the best strategy fighting Lee, hold and fight when he felt was necessary, and wait for someone like Sherman to come to Lee's rear. McClellan actually did a competent job at executing the role assigned him in Gen. Scott's Anacondas plan: "sit tight, hold Washington, and let the Navy squeeze the Confederacy." Problem was, Scott died before he could remind Lincoln and the Eastern press of this plan, so McClellan and his successor were spurred, repeatedly, into spasmodic efforts to take Richmond and points South.
Interestingly this suggests that McClellan's notoriously defensive instincts may well have been sound for the theater… and that Lee had the luck of a cushy but highly visible assignment, as well as the luck of facing undistinguished Union Generals plagued by the ongoing surveillance of an armchair audience.
Sherman understood the very constitution of the southern elite, and he understood the very fundamental reason to why they wanted war. He knew the southern aristocracy was a patrician society with excess pride and their fundamentally reason for fighting was to protect their patrimony: slaves, land and mansions. Conversely, the average Confederate soldier's well being was never considered.
Sherman is misunderstood by just about everyone, that's because he didn't follow the Marquess of Queensbury rules of boxing, he threw off the gloves. He demolished the heartland of the Southern aristocrats: their land and slaves—and left them impotent and discredited before their helpless women and children. Facing little opposition once they left Atlanta, Sherman's men destroyed the very infrastructure that supported slavery and upheld the slaveholding elites—plantations, communications, factories, and government facilities. Southern military officers put great capital in the idea of the sanctity of the Southern homeland. They deemed themselves great raiders and marauders, who harassed fixed garrisons and terrorized timid populations. Sherman, however, gave the Confederacy the raid of its life. The central objective could be summed up quite simply: Freeing the unfree and humiliating the arrogant.
Sherman goes down in history similar to a Greek tragic hero, like Ajax. He was the only general of the entire CW who could have done the job to end the war. But that's never discussed, the manner he did it in is constantly discussed because sanctimonious people who think they're sober and judicious shout out their fraudulent accusations from their fictional ivory tower. Ajax deserved Achilles armor and Sherman deserves Lee's armor.
I think if the Union would kept McLellan in charge of the east and cut Sherman Loose a little earlier the war could been over sooner, both generals, IMO, had the right strategy to end the Confederates reign of terror. I do believe that the Confederates would have been doomed no matter what that strategy.
