Forcing the Confederate army to surrender and shortening the Civil War was all a result of the General Grant's plan of attrition. Since Grant's plan involves fighting battles constantly without rest that meant the Rebel Army had to also deal with the same disadvantages.
The dissimilarity between Confederacy and the Union in the matter is that Grant had more men to make use of and dispose of while Lee had the same men who would have to endlessly fight.
Since Grant's troops were well rested once moved they were able to attack with 110% but the same could not go for the Confederates who will have to use troops that are fatigued.
Therefore whenever the Union regained their troops and stirred the Confederates were collapsing as a threat and force to Grant. There would soon be tiny amount left of the Confederate troops to fight which will later make them surrender.
