General William T Sherman explained that his aim was to relentlessly pursue the confederates and make them fear and dread him and the Union army. Which wartime strategy is represented by this idea?

Sherman's strategy can be classified as total war. Total war involves not only engaging in military battles, but also targeting the enemy's economic, social, and civilian infrastructure in order to break their will to fight. Sherman's brutal "march to the sea" and his scorched earth tactics in the Confederate states exemplify this approach to warfare.
