Sherman's March to the Sea is the name commonly given to the military Savannah Campaign in the American Civil War, conducted through Georgia from November 15 to December 21, 1864 by Maj. Gen. William Tecumseh Sherman of the Union Army. The campaign began with Sherman's troops leaving the captured city of Atlanta, Georgia, on November 15 and ended with the capture of the port of Savannah on December 21. His forces destroyed military targets as well as industry, infrastructure, and civilian property and disrupted the Confederacy's economy and its transportation networks. Sherman's bold move of operating deep within enemy territory and without supply lines is considered to be revolutionary in the annals of war.
