Had nothing to do with usage. Meade (at Gettysburg) and then Grant were the first in the East who were willing to pay the Butcher’s Bill.
When Meade and then Grant got hit hard, they didn’t fall back, they kept moving.
Lincoln gave Meade a hard time about letting Lee get away after Gettysburg, but, the weather had more to do with that than Lee or Meade. Meade followed as fast as he could get the army to move. He still had 2 fresh Corps in his Army, while Lee had nothing left.
Meade gets the short stick on a lot of things that happened because Grant was the overall Commander of the US forces. He should be remembered better.
Meade was a very capable General. You are correct, Grant’s decision to co locate his headquarters near the Army of the Potomac overshadowed Meade’s accomplishments as Commander of the Army of the Potomac
