Fredendall was absolutely incompetent in North Africa in my opinion. I think the fact that he was close to Marshall was the only thing that saved his butt. He was promoted out of there in order to get rid of him without making waves.
The other name I recognize (besides Stilwell) is McGruder but I cant remember from where right at the moment. Maybe he served under Patton?
A Major General John B. Magruder served under Robert E. Lee.
