True.

to be clear i’m a “grant guy” and consider lee a traitor, and generally see the entire confederacy the same way

Understood.

And I don't feel the need to over-demonize Lee. He chose to serve an evil cause, though. And that is a taint he chose to bear.

And Marshall is, objectively, right about who the truly great commanders were in the war (though the Union also had some terrible ones, of course).

Grant was not a cream of West Point type. But he did graduate from West Point.
