William Tecumseh Sherman was a prominent Union general during the American Civil War. He is best known for his "March to the Sea," a military campaign in which he led Union forces from Atlanta to Savannah, Georgia, destroying infrastructure and resources along the way. This strategy aimed to demoralize the Confederate army and civilian population. Sherman's tactics and aggressive approach to warfare made him a controversial figure, but he is widely recognized for his significant impact on the outcome of the Civil War. After the war, Sherman served as Commanding General of the United States Army and was involved in various military and political activities during the Reconstruction era.
