Truth is that the southern command with Lee was doing pretty good against their northern Yankee opponents until Lee fell vivtim to human vanity thinking in his mnd that he was invinceable and led his army, which followed orders, to many unnecessary deaths.. That was the start of the downfall of the Rebel uprising...
The final act was when Lincoln finally realized that the black men as soldiers would give him aditional manpower and force the South simply could not match in numbers..
Lastly, the straw the broke the camel's back: GRANT and Sherman. Lee finally had a worthy foe to fight against.
He had it pretty easy up until then. Grant and Sherman actually wanted to fight their enemy while all the other former commanders were pantywaists, always fearing that they may be facing far superior numbers and always needing more andm ore unnecessary re-inforcements.
Burnside should have been court martialed and SHOT for the murder of all those men at Fredericksburg.. But since it was not him facing the fire from behind the wall and the artillery from Longstreet, why did he care?
It was needless waste of men's lives.
Lee finally met his match with Grant and his right hand, Sherman.. These were Generals who led teir armies in the fighting and had superior numbers, equipment, supplies, and the men knew they were fighting to win, not lose...
Morale is everything. When it shifted, that was the end of the Southern Gallant resistance.
Lee is still a great strategist.. He did much with little. I admire him greatly. Longstreet was the best general the confederacy had in my view. He was not reckless yet when he went to battle, he fought to win...
He jknew when it was right to initiate the battle and when not to but wait for better conditions and field advantage.
Lee should have listened to him instead of allowing his bad idea to control his thoughts.
He was though the best the South had as a strategist and tactician. He put up a heck of a fight.
