I don't know if I can agree that Bragg was the worst. His initial plans were always solid IMHO, with the exception of his approach to the Tullahoma Campaign. Bragg had two main downfalls, one has been stated, he could not get along with his subordinates and could not endear himself to them, to make them want to fight for him. Secondly, Bragg was unable to adapt to the changing Battlefield. Once he came up with a plan, he had the tendency to not change it regardless of how the union countered him...he would just go ahead. Bragg also had problems with communication. His Chickamauga Campaign was wrecked by his vague orders to various subordinates....but we still have to consider his original plans which on paper, were all good.
