How did the actions of union generals grant an sherman affect the outcome of civil war

The actions of the Union general’s Grant and Sherman did have a direct effect on the outcome of the civil war. During this civil war general Grant was considered the best soldier and he did prove his name right by capturing both the Fort Donelson and Vicksburg. On the other hand General Sherman marched through Georgia and Carolinas and this resulted in weakening the enemies logistically and psychologically.  This team is considered the main reason behind the Union’s winning of the civil war.

Both countries had to aprove annexation.
