I meant in the Eastern Theater the Confederate Forces in the Western Theater were pretty weak considering their defeat at Shiloh a year earlier.
What does that matter? The West effects the East and it wasn't short after Chattanooga that Grant attacked Lee. Nor did Meade just sit there. There was the https://en.wikipedia.org/wiki/Bristoe_Campaign and https://en.wikipedia.org/wiki/Battle_of_Mine_Run after which Meade went into winter quarters which is common in war.
