Final answer:
Confederate commanders would adjust troop movements during battles by trying attacks on the opponent's flanks and then going up the middle if the flank attacks failed.
Step-by-step explanation:
In battle, when adjusting or changing troop movements to compensate for the other side's actions, Confederate commanders would employ various strategies and tactics. One common strategy was to attempt attacks on the opponent's flanks. If these flank attacks failed, they would then try to go up the middle. This approach allowed the Confederates to adapt to the movements of the Union troops and exploit any weaknesses or gaps in their lines.
