William TecumsehSherman

Explanation:

American soldier, businessman, educator, and author. He served as a general in the Union Army during the American Civil War (1861–65), receiving recognition for his command of military strategy as well as criticism for the harshness of the scorched earth policies he implemented in conducting total war against the Confederate States. British military theorist and historian B. H. Liddell Hart declared that Sherman was "the first modern general.

Born in Ohio to a politically prominent family, Sherman graduated in 1840 from the United States Military Academy at West Point. He interrupted his military career in 1853 to pursue private business ventures, and at the outbreak of the Civil War he was superintendent of the Louisiana State Seminary of Learning & Military Academy (now Louisiana State University). Sherman distinguished himself at the First Battle of Bull Run in 1861, before being transferred to the Western Theater.
