Scorched-earth defense
The scorched-earth defense is a form of risk arbitrage and anti-takeover strategy.
Western Theater of the American Civil War
Sherman's Savannah Campaign is more popularly known as the March to the Sea. He and Grant believed that the Civil War would end only if the Confederacy's strategic, economic, and psychological capacity for warfare were decisively broken. Sherman therefore applied the principles of scorched earth, ordering his troops to burn crops, kill livestock, consume supplies, and destroy civilian infrastructure along their path. This policy is one of the key tenets of a strategy of total war.
