What was the significance of the battle of sherman's march?

From November 15 until December 21, 1864, Union General William T. Sherman led some 60,000 soldiers on a 285-mile march from Atlanta to Savannah, Georgia. The purpose of this "March to the Sea" was to frighten Georgia’s civilian population into abandoning the Confederate cause. Sherman’s soldiers did not destroy any of the towns in their path, but they stole food and livestock and burned the houses and barns of people who tried to fight back. The Yankees were "not only fighting hostile armies, but a hostile people," Sherman explained; as a result, they needed to "make old and young, rich and poor, feel the hard hand of war." General Sherman’s troops captured Atlanta on September 2, 1864. This was an important triumph, because Atlanta was a railroad hub and the industrial center of the Confederacy: It had munitions factories, foundries and warehouses that kept the Confederate army supplied with food, weapons and other goods. It stood between the Union Army and two of its most prized targets: the Gulf of Mexico to the west and Charleston to the East. It was also a symbol of Confederate pride and strength, and its fall made even the most loyal Southerners doubt that they could win the war. ("Since Atlanta," South Carolinian Mary Boykin Chestnut wrote in her diary, "I have felt as if ... we are going to be wiped off the earth.")
