10. Ulysses S. Grant
Ulysses S. Grant commanded Union forces with unyielding aggression during the American Civil War. His willingness to engage in costly battles—such as Shiloh and the drawn-out siege of Petersburg—resulted in staggering casualties on both sides. Grant’s strategy of relentless offense earned him criticism for perceived ruthlessness, yet it proved decisive in breaking Confederate resistance. His leadership, though marked by immense bloodshed, was instrumental in preserving the Union and ending the conflict.
