Name me one major Civil War battle where the Union Army had a four or five to one manpower advantage.

Your attempted point would be relevant if the entire war was one battle. You know very well that Grant ground down Lee because the South couldn't simply replace the losses as the North could.

4 to 1 manpower will always win in the end.

at no time in the Civil War did the Union Army have a 4 to 1 manpower advantage over the Confederate Army.
