How did the generals on both sides perform in the civil war?

During the Civil War, Union generals like Ulysses S. Grant and William Tecumseh Sherman proved effective through their aggressive tactics and ability to coordinate large-scale operations, ultimately leading to the Union's victory. Meanwhile, Confederate generals such as Robert E. Lee and Stonewall Jackson demonstrated remarkable military skill and strategic ingenuity, achieving significant victories despite resource limitations. However, the persistent pressure of Union resources and manpower ultimately overwhelmed Confederate forces, highlighting the contrasting effectiveness of leadership under differing circumstances. Overall, leadership performance varied significantly, impacting the war's outcome.
