On the "first day" what is an apparent problem with the Confederate leadership?

In Chapter Six, we learn that Lee was not happy that Ewell didn't take Cemetery Hill. When Lee learns that Early influenced Ewell, Lee sends for Ewell to discuss the situation. Ewell confesses that he believes that he can take the hill the next day and apologizes for his caution. This episode emphasizes the confusion between the leaders of the Confederacy during the battle at Gettysburg as foreshadowed in the previous chapter and further complicates the events of this day which opens the battle on a sour note, foreshadowing the eventual outcome of the battle.
