I've always found it interesting that Hooker was never actually fired by Lincoln. He quit due to an argument with headquarters over troops positioned at Harpers Ferry. For the sake of discussion, let's say that for once in life Hooker is less impulsive and decides to stay on as leader of the Army of the Potomac. Does he pursue Lee into Pennsylvania, or does he focus on simply staying between the Army of Northern Virginia and Washington? Once a pitched battle occurs, does Hooker agressively attempt to get revenge against Lee, or does he go into the defensive mode that Meade did? (what's funny is that this was the perfect startegy at the time, as Lee was far too confidant in his forces after Chancellorsville)
I'll offer my interpretation shortly.
